Sustainable concrete: Potency of sugarcane bagasse ash as a cementitious material in the construction industry (original) (raw)

Increasing demand and consumption of cement investigators, researchers and scientist made in examination of alternate binders that are biodegradable and contribute towards waste management. The construction industry is the foremost consumer of natural resources which led to exhaustion of good quality natural sand (fine aggregate). This situation constrains us to explore alternative materials for cement and fine aggregate. Sugarcane bagasse ash is a left-over industrial byproduct which is used as a replacement of both natural sand and cement. The use of industrial and unindustrialized(agricultural) waste produced by industrial processes has been the attention on waste reduction. Juice is dig out(extracted) from sugar cane then ash is produced by burning. This research scrutinizes the possibility of using sugarcane bagasse ash as partial replacement of specific ingredients in concrete. In this paper SCBA has been chemically and substantially categorized and partially replaced fine aggregate in the ratio of 0%, 10%, 20%, 30% and 40% and 10% by the weight of cement in concrete. The mix proportion for M25 grade concrete was derived. Our study gave an effective result for the replacement. We could get a satisfactory concrete with SCBA content of 10% and 30% replacement for cement and fine aggregate respectively.

Sugarcane is one of the main cash crop grown in around 115 countries. The waste produced after its use as raw material is dumped on open lands. Detail estimation of sugarcane bagasse ash (SCBA) production on basis of sugarcane production all over as well as mainly in India is carried out in this study. Use of SCBA as a supplementary cementitious material adds sustainability to concrete by reducing the CO2 emission during cement production. The positive effects of SCBA as a partial replacement of cement on the mechanical properties of concrete are recognized through different researches; however, the overall improvement depends on the durability properties of SCBA in cementitious medium. In this study, durability properties of conventional concrete utilizing SCBA sourced from sugar factory site have been investigated. Concrete mixtures with SCBA content ranging from 0% to 30% of total binder were used. The compressive strength, ultrasonic pulse velocity and loss in weight of the conc...

The disposal of solid waste in open environment is a serious alarming concern that needs immediate attention from the researchers. The hazardous solid agro-industrial wastes which include: wheat straw ash, rice husk ash, corn cob ash and sugarcane bagasse ash (SCBA), having pozzolanic properties, have a versatile use in concrete. The solid pozzolana enhances the various concrete properties by the reaction of silicates with calcium hydroxide in the presence of water, which in result generate a saturated zone of calcium silicate hydrate (CSH) gel. This C-S-H gel reduces the amount of calcium hydroxide C(OH)2 during the hydration process of cement. Very limited research works have been done on concrete by partially replacing cement with SCBA. This research work was focused on evaluating the properties of concrete by partially replacing cement with SCBA at 0, 5, 10, and 15 percentages. Compressive strength, Strength activity index, and water absorption of all mixes were examined. And it was observed that all SCBA mixes showed an increase in compressive strength and at 10% replacement the strength activity index was at a peak of 115.67%, but all the SCBA mixes showed a strength activity index greater than 75% which satisfied the standard specification. The water absorption test for all SCBA mixes showed a slight increase in water absorption.

This paper presents the use of sugarcane bagasse ash (SCBA) as a pozzolanic material for producing high-strength concrete. The utilization of industrial and agricultural waste produced by industrial processes has been the focus on waste reduction. Ordinary Portland cement (OPC) is partially replaced with finely sugarcane bagasse ash. In this research physical characteristics, chemical combination (XRF test), TG-DTA were investigated and compared with cement.The concrete mixtures, in part, are replaced with 0%, 10%,15%, 20%,25% and 30% of BA respectively. In addition, the compressive strength, the flexural strength, the split tensile tests were determined. The bagasse ash was sieved through No. 600 sieve. The mix design used for making the concrete specimens was based on previous research work from literature. The water –cement ratios varied from 0.44 to 0.63. The tests were performed at 7, 28,56 and 90 days of age in order to evaluate the effects of the addition SCBA on the concrete. The test result indicate that the strength of concrete increase up to 15% SCBA replacement with cement.

With the increasing demand and more consumption of cement in construction and improper waste management, researchers are always in search of different cement replacing materials. Due to the vast production of sugar cane in India, huge amount of sugarcane bagasse is being produced and which is a waste product coming out of sugar industries. Sugarcane bagasse ash is a byproduct of sugar factories found after burning sugarcane bagasse. Sugarcane bagasse is a fibrous waste product of sugar refining industry along with ethanol vapor. The utilization of industrial and agricultural waste produced by industrial process has been focus to waste reduction. The present study has been focused on assessing performance of SCBA concrete in different curing environments by the partial replacement of ordinary Portland cement with different weight percentages of SCBA (0%, 5%, 10%, 15%, 20% and 25%). The tests were conducted on cubes and cylinders and prisms at various ages of concrete i.e., 7, 28 and 56 days to assess the strength aspects of SCBA concrete. From the present study it is evident that, utilization of waste material sugar cane bagasse ash can be advantageously used as a replacement of cement up to 5% without reduction in strength of concrete. Also, it can be observed that, SCBA concrete performed better even in aggressive environments when compared to ordinary concrete even at later stages.

Sugarcane bagasse ash is a byproduct of sugar factories found after burning sugarcane bagasse which itself is found after the extraction of all economical sugar from sugarcane. The disposal of this material is already causing environmental problems around the sugar factories. On the other hand, the boost in construction activities in the country created shortage in most of concrete making materials especially cement, resulting in an increase in price. This study examined the potential use of sugarcane bagasse ash as a partial cement replacement material. In this study, bagasse ash sample was collected from Wonji sugar factory and its chemical properties were investigated. The bagasse ash was then ground until the particles passing the 63μm sieve size reach about 85% and the specific surface area about 4716 cm2/gm. Ordinary Portland cement and Portland Pozzolana cement were replaced by ground bagasse ash at dif erent percentage ratios. Normal consistency and setting time of the pastes containing Ordinary Portland cement and bagasse ash from 5% to 30% replacement were investigated. The compressive strengths of dif erent mortars with bagasse ash addition were also investigated. Four dif erent C-35 concrete mixes with bagasse ash replacements of 0%, 5%, 15% and 25% of the Ordinary Portland cement were prepared with water to cement ratio of 0.55 and cement content of 350kg/m3 for the control mix. The test results indicated that up to 10% replacement of cement by bagasse ash results in better or similar concrete properties and further environmental and economic advantages can also be exploited by using bagasse ash as a partial cement replacement material.

There are lots of environmental impacts of cement on our ecology. Cement industry creating environmental problem by emission of CO2 during manufacturing of cement. Present time many researchers are more focusing towards the environment issue globally. Portland cement is the conventional building material that actually is responsible for about 5%-8% of global CO2 emissions. On the other side Sugarcane Bagasse ash (SBA) generated in sugar mill creating environment issue as most of the part is used as a land fill. In this research work the suitability of sugarcane bagasse ash (SBA) in concrete used as partial replacement with fine aggregate and cement as well. The cement and fine aggregate was partially replaced by SBA at 10%, 20%, 30% and 40%, by weight in normal strength concrete. Sugarcane bagasse ash which is taken from one of the sugar mill of Madhya Pradesh used in M 25 grade of concrete by replacing cement and fine aggregate in percentage by weight and compare with conventional concrete and to check the feasibility of sugarcane bagasse ash in concrete. Fresh concrete tests like compaction factor test and slump cone test must examined as well as hardened concrete tests like compressive strength at the age of 7, 14 and 28 days , and flexural strength at the age of 7 and 28 days is to be obtained.

The test result indicate that the strength of concrete increase up to 15% SCBA replacement with cement.

Sugarcane Bagasse Ash (SCBA) is one of the most common types of agricultural waste. By its availability and pozzolanic properties, sugarcane bagasse ash can be utilized as a partial replacement for cement in the production of sustainable concrete. This study experimentally investigated the impact of employing two types of sugarcane bagasse ash as a partial substitute for cement up to 30% on the compressive strength, flexural strength, and Young’s modulus of the concrete mixture. The first type of bagasse ash used was raw SCBA, which was used as it arrived from the plant, with the same characteristics, considering that it was exposed to a temperature of 600 °C in the boilers to generate energy. The second type of bagasse ash utilized, called processed SCBA, was produced by regrinding raw SCBA for an hour and then burning it again for two hours at a temperature of 600 °C. This was done to improve the pozzolanic activity and consequently the mechanical properties of the concrete mixtur...
