To attain desirable strength of soil, soil reinforcement has been playing a pivotal role since many decades. Although there are many well established methods to reinforce the soil, but now-a-days people are looking for low-cost reinforcing materials. In Bangladesh jute waste is not being used effectively, although jute production is quite good in amount. From this point of view, in this study jute fiber is selected as reinforcing material and focused on improvement of compressive strength of soil with this. Varying proportions of Jute fiber as 1%, 2%, 3% and 4% have been mixed with soil to make the samples to be tested. The result indicated that the sample prepared with 3% of jute fiber gives the highest value in Unconfined Compressive Strength (UCS) test, and adding more than 3% of jute fiber tends to decrease the UCS value. As this study has been done keeping in mind about the embankment construction process in the coastal zones of Bangladesh, where grass turfing is done to protect soil from erosion and inorganic fertilizer is used to grow up the grass which has long term adverse effect on environment. On the other hand jute is 100% biodegradable, when it comes to contact of moist soil, after a certain period it acts as natural fertilizer that helps to grow up the grass and make the root of grass stronger to hold the soil.

Jute is very important natural fibre whose production, usage and global consumption if only second to cotton. The fibre which is obtained from the corchorus of the hibiscus family is used for the production of several products globally of which ropes and cordages are chief among them. The study sort to investigate the cultivation and usage of the jute fibre in the Upper East region of Ghana. Use was made of questionnaires and interviews in gathering the data for the ethnographic study and the areas visited for the investigation includes Sumbrungu, Bolgatanga, Yikene and Kulbia in the Bolgatanga Metropolitan area as well as Navrongo, Pungu, Nayania and Vunania in the Kassena-Nankana Municipal area. In the Upper East region, the fibre is used for products such as ropes, mats for burial, door mats, and bags among others. It was revealed that the sale of products made from jute is facing a stiff completion from other products made from synthetic materials such as nylon. The study therefore recommends training of manufacturers to know how to integrate jute with other synthetic fibres to improve on the performance as well as the aesthetic appeal of the products.

In the present era, a number of researchers are using either industrial or agricultural priceless products as a basic source of raw materials for the construction industry. ese waste products are economical and helpful in producing a sustainable environment and reducing environmental pollution, which is called handling waste products. However, this research work was conducted on concrete containing 0.25%, 0.50%, 0.75%, and 1% of jute fiber as reinforcement material and 10%, 20%, 30%, and 40% of wheat straw ash (WSA) as replacement for fine aggregates. Moreover, the separate and combined effect of jute fiber and WSA as a replacement for sand ingredient in concrete is to determine the fresh and hardened properties of concrete. In this research, a number of concrete samples were prepared with 1 : 1.5 : 3 mix proportion at 0.54 water-cement ratio and cured at 28 days. e experimental outcomes displayed that the compressive, splitting tensile, and flexural strengths improved by 32.88 MPa, 3.80 MPa, and 5.30 MPa at 0.50% of jute fiber along with 30% of WSA at 28 days consistently. Similarly, the modulus of elasticity was developed while the dosages of jute fiber and WSA increased together in concrete. Moreover, the permeability and workability of concrete were reduced while utilized jute fiber and WSA increased together in concrete.

There is a huge need for new materials in all fields of engineering; this invites the development of new materials which suits the need. Utilization of biodegradable materials i.e. natural fibers for various applications to preserve the environment from synthetic fibers invites the development of natural fiber reinforced polyester composites. In a country like India which is producing an enormous amount of agricultural solid waste (in the form of leaf, fruits, stems etc.) there is lack of marketing for the above-said wastes if this can be improved the farmers may get benefited. Natural fiber reinforced composites are preferred than conventional materials because of their advantages like low density, lightweight, high strength to weight ratio, low cost, high toughness, and biodegradability. The present investigation deals with the preparation of jute, pineapple leaf fiber and jute-pineapple leaf fiber (Hybrid) reinforced polyester composite and to determine the tensile, flexural and impact properties with increase in percentage weight fraction of the fiber and to compare the properties of the composites.Further, the experimental results will be validated through ANSYS software.

Nowadays, bio-derived cellulose nano-fibrils based nanocomposites is gaining utmost interest in the area of barrier films for food packaging, as reinforcing filler to make biodegradable nanocomposites with different biopolymers for various applications such as transdermal drug delivery, edible packaging and tissue scaffolding. Ultrasound-assisted preparation of hydroxypropylmethylcellulose based nanocomposites with cellulose nano-fibrils were carried out following solution mixing technique. The crystalline nature of cellulose nano-fibrils has been scrutinized by X-ray diffraction study. The field emission-scanning electron micrographs of cellulose nano-fibrils revealed a network of nano-fibrillar morphology. The Fourier transform infrared spectroscopy results of cellulose nano-fibrils confirmed the removal of lignin and hemicellulose from raw jute (Corchorus olitorius L.) fibres. The storage modulus and tensile properties of hydroxypropylmethylcellulose films increased up to the addition of 1.00 wt% cellulose nano-fibrils. The moisture affinity of hydrophilic hydroxypropylmethylcellulose has also been reduced at 1.00 wt% cellulose nano-fibrils loading. The impact of cellulose nano-fibrils loading on the cumulative percentage of drug release from prepared nanocomposites films has been explored accordingly. By utilizing these versatilities of cellulose nano-fibrils, the fabricated nanocomposites are expected to be highly promising in the area of packaging and transdermal drug delivery system.

In the case of polymer composites reinforced with natural fiber woven fabrics, microstructural calculations are extremely difficult to perform due to their characteristic variability, among others their mechanical properties. The aforementioned scientific problem has not been thoroughly investigated, hence the purpose of this work was to assess the possibilities of predicting the properties of a composite reinforced with flax woven fabric by micromechanical calculations using the Mori-Tanaka and the double inclusion homogenization models. In addition, the second important utilitarian problem that was undertaken in the work was assessment of the impact of the size of the representative volume element (RVE) on the obtained results. The analyses were carried out for composites based on epoxy resin reinforced with flax fabrics: plain, 2x2 twill and 3x1 twill types. Based on the performed calculations, it was found that the obtained results depend on the type of weave in the fabric used, the size of the RVE, the number of yarn bands in the RVE and the appropriately selected homogenization method. Guidelines useful for evaluating the optimal RVE size depending on the type of weave were formulated. WPŁYW PARAMETRÓW GEOMETRYCZNYCH W REO NA WŁAŚCIWOŚCI SPRĘŻYSTE MATERIAŁÓW KOMPOZYTOWYCH ŻYWICA EPOKSYDOWA-TKANINA LNIANA W przypadku kompozytów polimerowych zbrojonych tkaninami z włókien naturalnych przeprowadzanie obliczeń mikro-strukturalnych jest wyjątkowo trudne do wykonania z uwagi na charakterystyczną dla nich zmienność, m.in. właściwości me-chanicznych. Wspomniany problem naukowy nie jest dokładnie zbadany, stąd celem niniejszej pracy była ocena możliwości prognozowania właściwości kompozytu wzmacnianego tkaniną lnianą poprzez obliczenia mikromechaniczne z wykorzysta-niem modelu homogenizacji Mori-Tanaka oraz Double Inclusion. Ponadto drugim istotnym problemem utylitarnym, który podjęto w pracy, była ocena wpływu wielkości reprezentatywnego elementu objętościowego (REO) na uzyskane wyniki. Ana-lizy przeprowadzono dla kompozytów o osnowie żywicy epoksydowej zbrojnej tkaninami lnianymi o splocie: płóciennym, sko-śnym 2x2 oraz skośnym 3x1. Na podstawie przeprowadzonych obliczeń stwierdzono, że uzyskane wyniki zależą od rodzaju splotu w zastosowanej tkaninie, wielkości REO, ilości pasm przędzy w REO oraz odpowiednio dobranej metody homogeniza-cji. Sformułowano wskazówki przydatne do oceny optymalnego wymiaru REO w zależności od rodzaju splotu. Słowa kluczowe: REO, kompozyty wypełnione włóknami naturalnymi, Digimat, len, MES, homogenizacja

The need for a "systemic" approach to reduce both carbon footprint and seismic vulnerability of the built environment is clearly evident nowadays. Therefore, the use of bio-based materials, is gaining consensus as a sustainable solution due to their low environmental impact and promising properties as a construction material. This paper investigates the performance of the raw jute fiber and jute threads in view of their possible use as thermal insulation and structural reinforcement in composite systems with inorganic matrices. Specifically, the physical, chemical and mechanical properties of the jute fibers, threads and diatons are investigated. They show that they have potential to be used as a construction material. In fact, water absorption of jute fibers, threads and diatons has been almost similar, ranging in between 1.83-2.50 g(water)/g(fiber), while the specific mechanical performance of fibers worsens as sample size grows from fibers to threads and diatons. Based on the results reported in the present paper, further studies are already under development with the aim to assess the actual thermal and mechanical response of jute-reinforced Textile-Reinforced Mortars (TRM) as a sustainable technology to thermal and seismic upgrading of existing masonry buildings.

The primary objective of this study to investigate the strength of cement mortar. Cement is part replaced by Rice Husk Ash up to 30%. Jute fiber were added in the percentage of 0.5%, 1%, 1.5%, and 2% by total weight of cement mortar. Jute fiber enhances the mechanical properties of cement mortar and also avoid crack propagation. The mixed specimen is cured for 7, and 28 days for observing compressive strength test results. Addition of small closely spaced, uniformly distributed fibers act as crack arrester, substantially increase static and dynamic properties with increasing water content. This paper results in the experimental study on the behavior of plain and fiber reinforced cement mortars with jute fiber. It has been resulted that the tested fiber reinforced mortars had no greater static and impact strength compared to plain mortar.

Soil is used as a building material in different parts of the world. Earth construction, with the least demand for resources, is economically the most efficient means for house construction in developing countries. The recent flood in Kerala (August 2018) resulted in a huge loss of lives, many lost their homes, houses partially destructed, landslides occurred, many animals died. The overall effect was devastating. Post-flood Kerala saw huge deposits of waste and clayey soil accumulated in lands, which needs to be cleared and life should be brought back to normal. Why can’t we use these deposits as raw material for construction? To study this possibility, deposited soil from the areas of Periyar, Kerala, where the most amount of deposits were found and several tests were conducted on it to check its efficiency. Different types of blocks were prepared from this soil with and without adding stabilizers. Tests such as compressive strength and total water absorption were conducted on these blocks to evaluate their strength and durability. Finally, the values and properties of prepared sample blocks were compared and its efficiency to be used as a construction block is proved. The block can be made in low-cost and is energy efficient. This paper is a review of the construction of such clay blocks produced from flood deposits. It’s an overview to demonstrate the scope of building walling using these clay bricks. Its advantages are realized in terms of rescuing the heritage and as a rediscovered environmentally friendly building material.

Now a days traditional metallic and alloy material are replaced with the fiber based composite material in numerous engineering application. The effect of stacking sequence on tensile and flexural properties of epoxy-based carbon and jute fiber composites has been investigated experimentally and numerically in this paper. Six layers of woven unidirectional jute fiber and four-layer of carbon fiber has been fabricated by vacuum assisted resin infusion process with five different stacking sequences. The tensile and water absorption behaviors of the prepared composite samples were experimentally studied as per the standard of ASTM. The obtained results from the experiments revealed that the stacking sequence of the fiber has a great effect on the tensile and water absorption properties of the composite. To validate the experimental result of the tensile test, the exact 3 D model of the composite laminates were imported to a Finite Element Analysis (FEA) software with the exact experimental condition. The predicted FEA results were compared with the experimental results and a good similarity between them has been observedxact experimental condition. The predicted FEA results were compared with the experimental results and a good similarity between them has been observed.

Triblock poloxamer copolymer (PM) has been extensively utilized to deliver various ophthalmic pharmaceutical compounds. The aim of efficient ophthalmic drug delivery strategy is to attain the longer precorneal resident time and good bioavailability of drugs. In this pursuit, the influence of cellulose nanocrystals (CNC) on the in situ ge-lation behavior of PM and in vitro release of pilocarpine hydrochloride from the nanocomposites formulations was studied. The critical concentration of gelation of PM being 18% (wt/v) was dropped to 16.6% (wt/v) by the addition of a very low percentage of CNC. The reinforcing nature of CNC via H-bonding in the in situ nanocompos-ite gel also led to an increase in gel strength along with the sustained release of loaded drugs when compared with the pure PM gel. All formulations revealed that the drug release mechanism is controlled by the Fickian diffusion. Thus, the CNC has a significant effect on the gelation behavior, gel strength, and drug release kinetics of PM-CNC formulations.

One field experiment was conducted to study the effect of applied nitrogen with different nitrogen doses i.e 40 kg/ha 80 kg/ha and 120 kg/ha and micronutrients application viz. control, foliar spray of 0.2% ZnSO4 and 0.2% FeSO4, soil application of ZnSO4 @ 25 kg/ha + FeSO4 @10 kg /ha,with three replication to enhance the yield and nutritional value of leafy vegetable jute. Significantly higher foliage yield and nitrogen content in leaves were recorded with 80 kg/ha. Protein content, micronutrient contents were at par with all nitrogen doses.Micronutrient application did not increase significantly either N or protein concentration in jute leaves, but higher values recorded with this application. Foliar application of Zn and Fe recorded higher value of Zn and Fe content in leaves compared to soil application. Therefore it may be concluded that application of 0.2% foliage spray of ZnSO4 and FeSO4along with recommended 80 kg of N/ ha not only enhanced the yield but also enriched the jute leafy vegetable with protein and Fe and Zn enrich will help to control malnutrition in human being.

The natural fibers such as jute, coir, hemp, sisal etc. are randomly used as reinforcements for composite materials because of its various advantages such as low cost, low densities, low energy consumption over conventional fibers. In addition, they are renewable as well as biodegradable, and indeed wide varieties of fibers are locally available. In this study, glass–jute fiber reinforced polymer composite is fabricated, and the mechanical properties such as tensile , flexural and impact behavior are investigated. The materials selected for the studies were jute fiber and glass fiber as the reinforcement and epoxy resin as the matrix. The hand layout technique was used to fabricate these composites. Fractured surface were comprehensively examined in scanning electron microscope (SEM) to determine the microscopic fracture mode. A numerical procedure based on the finite element method was then applied to evaluate the overall behavior of this composite using the experimentally applied load. Results showed that by incorporating the optimum amount of jute fibers, the overall strength of glass fiber reinforced composite can be increased and cost saving of more than 30% can be achieved. It can thus be inferred that jute fiber can be a very potential candidate in making of composites, especially for partial replacement of high-cost glass fibers for low load bearing applications.

The technique of fibre-reinforced polymers (FRP)-strengthening of concrete columns has emerged in recent years as an excellent alternative to the iron plate reinforcement and strengthening using reinforced concrete cover. That is because the mechanical properties of fibre-reinforced polymers (FRP) being (lightweight, has excellent tensile resistance, has high corrosion resistance) and finally speed of work execution. In this research, the behaviour of short reinforced concrete columns with circular sections and strengthened with treated natural jute and non-treated jute fibres was studied. The practical program includes casting and testing 24 specimens of short circular tubed reinforced concrete columns where laboratory testing was carried out under axial compression load. All columns were 700 mm in height and 150 mm in diameter. Regarding fibre treatment, there are four methods used in this research; chemical treatment, thermal treatment, red iron oxide treatment and epoxy treatment. The results showed that the columns strengthened by jute fibres, in general, have higher durability than the unstrengthened columns. Moreover, it was shown that the treatment of jute fibres in the four different ways has a significant effect on improving the performance of jute fibres in the process of strengthening in different proportions depending on the nature of the treatment, where the strengthening of the regular untreated fibres led to an increase in ultimate load capacity by 24.8%. Besides, the process of jute fibre treatment (chemical, thermal, red iron oxide and liquid epoxy) resulted in an increase of ultimate load by 35.6%, 39.28% 48.56% and 59.07% respectively compared with reference columns. The results also showed that the strengthening of jute fibres reduced the agitation and longitudinal deformations of the columns at the same load values as well as increased both ductility and toughness with the increase of ultimate load.

Biodegradable plant fiber reinforced poly (lactic acid) (PLA) composites are potential replacements for traditional synthetic fiber reinforced composites. These may experience hygrothermal aging from the combined effects of moisture and heat. The effects of aging in water at 50°C on water absorption, chemical degradation of the fibers and matrix, and the tensile properties of a jute fiber/PLA composite have been correlated with changes in the internal structure, observed by high-resolution computed 1 This is the authors' copy of a paper accepted for publication in the journal Composite Science and Technology https://doi.org/10.1016/j.compscitech.2019.01.018 2 X-ray tomography. Water absorption during aging causes fiber/matrix interface failure and then matrix embrittlement, and these are detrimental to the tensile strength, stiffness and ductility.

Productivity progress and learning in manufacturing have been widely discussed in the literature. A typical time-graph of manufacturing productivity starting from the commencement of a manufacturing process shows a period of continuous increase before it eventually levels off. The rising phase is popularly known as the "start-up" phase. It is generally believed that learning is the principal contributor to productivity increase in this phase and is likely to be confined to this phase. In other words, it is widely believed that learning is a finite process and once it stops, the productivity level stabilizes and remains roughly stationary thereafter. The purpose of this paper is to estimate learning and productivity progress in the start-up phase of jute manufacturing plants in Bangladesh.

Experiments were conducted on jute fiber reinforced polypropylene (PP) composites
to optimize the content of fiber in the composite. It was found to be 40wt%. In the present
study, effects of hybridizing glass fibers and carbon in the optimized jute fiber reinforced
PP composite have been studied. The properties such as tensile, flexural and impact with
respect to randomly oriented jute, glass and carbon fiber variations in the PP matrix are
considered. Jute, glass and carbon fibers reinforced PP matrix composites with different
fiber contents were prepared by injection molding. Matrix content is kept as 60wt%. The
hybridization of the fibers considered by weight fraction for jute and glass is 20:20, for
jute and carbon is 20:20 and jute, glass and carbon is 20:10:10. Results showed that
tensile, flexural and impact properties have been improved with glass fiber hybridization
and further improvement in these properties are observed with carbon fiber hybridization.
When glass and carbon fibers are added in 10:10 weight percentage the considered
mechanical properties have been found to be nearer to the composite with 20 wt% of
carbon.

Jute is an important natural fibre occupying second place in economic importance only to cotton. More importantly it is a commodity on which many households in the country depend for their cash earnings. However, the contribution of jute fibres for technical applications is limited at present. In this research, the suitability of jute fiber when incorporated into epoxy matrix was studied in an investigative series of experiments with a view to widen the share of jute fibers for engineered applications. Composite specimens containing nonwoven jute mat and alkali treated short jute fibers with different weight percentages (1, 2 wt%) were prepared and subjected to thermal analysis in order to study the effect of fiber geometry on thermal behavior of composites.

Short jute fiber (2-3 mm) reinforced polypropylene PP-based composites (20% fiber by weight) were fabricated using compression molding and the mechanical properties were evaluated. Tensile strength (TS), tensile modulus (TM), elongation at break (Eb%), flexural strength (FS), flexural modulus (FM), impact strength (IS), and hardness of the composites were found to be 32 MPa, 850 MPa, 12%, 38 MPa, 1685 MPa, 18 kJ/m 2 and 96 shore-A, respectively. Then short E-glass fiber (2-3 mm) reinforced PP-based composites (20% fiber by weight) were fabricated and mechanical properties were compared with short jute-based composites. Short jute-based composites showed excellent mechanical properties and comparable to short E-glass-based composites. Soil degradation test of both types of composites indicated that jute/PP composites significantly lost much of its mechanical properties but E-glass/PP composites retained major portion of its original integrity. Interfaces of the degraded composites were investigated by scanning electron microscopy and supported the biodegradation properties of jute/PP composites.

In this study, jute fiber was used as fibrous material in concrete to improve the overall strength. Jute fiber of different lengths and percentages were selected. Three percentages of jute fibers were implemented here, such as 0.1%, 0.25% and 0.5% of the volume of plain concrete. Again, three lengths of jute fiber were selected such as 10 mm, 15 mm and 20 mm for each percentage to find out the best potential percentage along with length. All these were done to compare the compressive strength and split tensile strength of jute fiber reinforce concrete (JFRC) with plain concrete to find out the best results. Total 30 numbers of cube were prepared for compressive strength tests and 30 numbers of cylinder for split tensile strength tests. They were loaded in 7, 14 and 28 days respectively and the strengths were noted and compared with each other. The cube has shown maximum improvement over compressive strength for 0.25% jute fiber of 10 mm length. The compressive strength was increased by 22.51%, 29.56% and 26.15% for 7, 14, and 28 days respectively compared to plain concrete. The cylinder also has shown maximum enhancement over split tensile strength for 0.25% jute fiber of 10 mm length. The split tensile strength was increased by 14.09%, 26.23% and 25.48% for 7, 14, and 28 days respectively compared to plain concrete. Here, the improvement was little for 0.1% jute fiber compared to 0.25%. However, the strengths has been dramatically reduced for 0.5%.
