EFFECT OF FOUNDRY SAND ON GEOTECHNICAL PROPERTIES OF MARINE CLAY

Soil stabilization means the improvement of stability or bearing capacity of soil by the use of controlled compaction, proportioning and/ or addition of suitable admixtures or stabilizers. The main objective of this study is to investigate the effect of foundry sand on the geotechnical properties of marine clay. The experiments were done on marine clay. The tests were conducted on soil admixed with foundry sand at different percentages and the results were compared with that of blank soil. Data presented includes maximum dry density, optimum moisture content, California bearing ratio and unconfined compressive strength. The study reveals that the CBR value of soil increases with the addition of foundry sand. The proposed technique can be used as an effective method in the field of soil stabilization and an effective disposal technique for foundry sand.

EFFECTS OF INDUSTRIAL WASTES ON GEOTECHNICAL PROPERTIES OF CLAYEY SOIL

The present work focused on studying the effects of liquid industrial waste on the geotechnical properties of clayey soil. The intact clayey soil samples, disturbed and undistutbed had been obtained from countryside city of Alexandria in 2013, which is located to the north of Babylon Governorate. While, the liquid industrial waste is side product disposed from of Al-Musayyib Thermal Electric Power Station, which includes solutions of acidic, alkaline and hydrocarbons. The clayey soil samples were contaminated artificially with four percentage (10, 20, 40 and 100) % by weight of water used in soaking process. The soaking process continued for 30 days. Based on the results of tests, the following observations are obtained: the different percentages of contaminant have slight effects on the chemical and physical properties of soil, but have significant effects on the mechanical properties such as shear strength parameters, where the shear strength parameters decreased by (5-35) %, and consolidation properties, where the coefficient of vertical consolidation increased by (7-28) % in compare with the properties of intact soil. The modulus of subgrade reaction decreased by (4-27) %.

Foundry sand and fly ash both are waste materials obtained from different industries imposing hazardous effect on environment and human health. Although utilization of foundry sand and fly ash are continuing to grow, but still there is substantial quantity that remains unutilized. The inherent properties of foundry sand and fly ash can be used to obtain an effective sub-grade material with combination of clayey soil and the problems of their disposal can be solved to some extent. The results show that with addition of foundry sand and fly ash to clayey soil, its strength and compaction characteristics are improved.

Influence of Contamination on Geotechnical Properties of Clayey Sand Soil

International Journal of Advances in Structural and Geotechnical Engineering

Generating large quantities of contaminated soil annually in all parts of the world poses a great threat to the environment and humans. In recent times there have been multiple sources of soil contamination. One of the most famous of these contaminants is the used engine oil. In this research, the effect of waste engine oilon some geotechnical properties of soil were studied. Laboratory tests including compaction and California bearing ratio (CBR tests were conducted on clean and contaminated soil. Contaminated soil samples were prepared by adding the waste engine oilat ratios of 4%, 8%, 12% and 16% of the dry weight of the samples. The results revealed a positive effect of the waste engine oilon the maximum dry density (MDD) and CBR values, but this improvement continued until the contaminant ratio of 8%. These values were decreased with further increase in the contaminant ratio to 16%.

Improve Geotechnical Properties of Soils Using Industrial Wastes: A Review

Civil Engineering Beyond Limits, 2020

The engineering problems of problematic soils are mainly related to their mechanical, physical, and mineralogical properties. Extensive efforts have been directed to mitigate damages that may happen for structures constructed on, or in these soils' types. Both conventional materials (e.g. cement, lime, etc.), chemical and produced materials were blended, mixed, or added to soils to improve their geotechnical properties. In the last years, different additives from the wastes of industrial processes have been adopted in engineering researches to improve soils. This paper reviews different industrial wastes materials (e.g., fly ash, blast slag, rice husk ash) as soil stabilizers, where the use of them has economic and engineering benefits. The effect of these materials on physical properties, compaction characteristics, compressive strength, and bearing ratio of soils have been presented, studied, and discussed. The contents of these materials are widely varied from reference to re...

STABILIZATION OF SUB GRADE SOIL BY USING FOUNDRY SAND WASTE

Due to various construction development projects undertaken all over the world there is a substantial increase in the production of waste materials like concrete, fly ash, plastic, rice husk, foundry sand etc. which create disposal problems. Foundry waste sand is produced in large quantity in foundry industries and is disposed in open land. Therefore use of foundry waste sand in foundation of buildings and in road constructions to improve bearing capacity of soil and to reduce the area of open land needed for its disposal and to preserve environment through resource conservation.Soil is a base of a structure which supports the structure from beneath and distributes the load effectively. The present study deals with stabilization of soil by using foundry waste sand in different proportion in original soil. In this study laboratory tests such as Atterberg's Limit Test, Direct Shear Test and California Bearing Ratio (CBR) Test were carried out for both modified and unmodified soil. The results show that Maximum Dry Density and CBR values were improved after addition of foundry waste sand to the soil.

Effects of Ground Granulated Blast Furnace Slag & Lime on the Engineering Properties of Clayey Soil: A Review

International Journal of Technical Innovation in Modern Engineering & Science, 2019

Clayey soils are problematic due to the reactions of their minerals, which gives them an exhibition of shrink-swell properties. The shrink-swell property obtains clayey soils as inappropriate material for direct utilisation in construction. In underdeveloped nations due to the remarkable development in road infrastructure, soil stabilisation has become the most efficient solution in construction industries. To make these soils more workable for construction, various methods (mechanical, chemical) and materials have been used. Cement, Lime, fly ash, and ground granulated blast furnace slag (GGBS) has usually used us stabiliser for developing the engineering properties of soil. The main focus of this review paper is on the utilisation of GGBS by-product and lime to enhance the geotechnical properties of the clayey soil. Experimental results of different tests like strength, microstructure, and compaction of various stabilizers and their percentages are evaluated and discussed. Lime and GGBS as local natural and industrial sources implied for chemical stabilisation. However, the reduction of waste material and its usage in construction has become an area of potential and promise.

Improvement of the geotechnical properties of a clay–sand mixture treated with lime

Innovative Infrastructure Solutions

The use of lime or sand as stabilizers gave satisfactory results in improving the physical and mechanical properties of the expansive soils. The main aim of this research is to study the effect of adding dune sand, lime and their combination on the behavior of an expansive clay soil. Dune sand and lime were added to the high plasticity clay soil (CH) within the percentage of 0-30% and 0-9%, respectively. According to tests results, it can be noted that both of dune sand and lime can improve the geotechnical properties of the expansive soil by reducing their plasticity and increasing their unconfined compressive strength. The combination of lime and dune sand can appreciably improve the studied properties of the clay soil compared to the use of dune sand or lime alone, especially with the optimal combination which consists of 20% dune sand and 3% lime. Denser soil structure with more flocculated soil particles and additional cementation products are observed when adding dune sand to the lime-treated soil compared to using lime alone.

Some engineering properties of stabilized clayey soils incorporating natural pozzolans and industrial wastes

Construction and Building Materials, 2011

Clayey soils are stabilized with various dosages of cement kiln dust, volcanic ash and their combinations. The influence of stabilizers is evaluated through Atterberg limits, standard Proctor compaction, unconfined compressive strength, splitting tensile strength, modulus of elasticity and California bearing ratio (CBR) tests. The durability properties of 14 stabilized soil mixtures are also investigated by studying the influence of water immersion on strength, water sorptivity and drying shrinkage. Correlations between strength, modulus of elasticity and CBR are also established. Developed stabilized soil mixtures have shown satisfactory strength and durability characteristics and can be used for low-cost construction to build houses and road infrastructures. The use of stabilized soils with locally available soils, volcanic ash and cement kiln dust can provide sustainability to the local construction industry.
