Modern concretes lay emphasis on high strength in order to reduce structural member sizes to reduce materials used; high early strength to promote fast construction; high durability to reduce maintenance costs; and the incorporation of industrial and agricultural wastes to reduce environmental degradation. The incorporation of industrial and agricultural wastes into concrete as cement replacement materials reduces the amount of cement used in the production of concrete and the CO2emissions arising from cement production. Sugarcane bagasse is a waste product from the extraction of juice from sugar cane. It is estimated that 1.7 million tons of bagasse are produced worldwide every year. Much of the bagasse is used as boiler fuel and to produce electricity, and the ash is dumped in earth fills, resulting in critical environmental pollution that requires immediate attention. Available literature shows that when burned under controlled conditions, a pozzolanic ash of high silica content ...

Effect of use of Sugarcane Bagasse Ash by partial replacement of Cement in Concrete
2019
The composition of concrete is cement, aggregate and water. With time and use of technology, the scientists discovered the benefits that came with use of admixtures in the concrete production. This project focuses on how Sugar Cane Bagasse Ash (SCBA) can be used to replace cement partially in order to improve the performance of concrete. Recycling of waste construction materials saves natural resources, saves energy, reduces solid waste, reduces air and water pollutants and reduces greenhouse gases. In addition to this, the effective use of recycled waste will act as a substitute for the materials that are conventionally purchased new and by adopting a policy such as this will be able to reduce the cost materials, save energy and help conserve resources. This will also lead to the possibility of reducing costs for companies, even though they will have to pay for the recycled materials. The Silica present in the Bagasse ash reacts with components of cement during hydration and impart...
In developing countries, accumulation of unmanaged agricultural waste has resulted in an increased environmental concern. Recycling of such agricultural wastes is the viable solution not only to pollution problem, but also the problem of land filling. In view of utilization of agricultural waste in concrete and mortar, the present paper reviews, utilization of sugarcane bagasse ash (SCBA) in different compositions that were added to the raw material at different levels to develop sustainable concrete and mortar. Various physico-mechanical properties of the concrete and mortar incorporating sugarcane bagasse ash are reviewed and recommendations are suggested as the outcome of the study. The study in turn is useful for various resource persons involved in using SCBA material to develop sustainable construction material.
An Examination the Use of Sugarcane Bagasse Ash as Cement Partial Substitutes in Concrete
International Journal of Innovative Research in Computer Science and Technology (IJIRCST), 2023
The strength and shrinkage of concrete that is combined with sugarcane bagasse ash particles are influenced by the size of the particles, as analyzed in this research article. A higher amount of water is required when utilizing Sugarcane Bagasse Ash (ScBA) in concrete. The strength of the mixture created with fine ScBA can be comparable to or greater than that of standard concrete. The ScBA waste produced from sugarcane contracts substantially as a consequence of the presence of minute components within it. In this study, the researchers utilized a material known as Sugarcane Bagasse Ash (ScBA) to substitute cement in concrete. The experiment involved testing the effectiveness of ScBA (at different percentages: 0%, 5%, 10%, 15%, and 20%) in strengthening M20 concrete over a period of 28 days. They compared it to regular concrete. The extent to which it could resist pressure and strain without snapping was measured. The reason behind burning Sugarcane waste (ScBA) for fuel is its ability to produce significant amounts of heat. Cement can be supplemented with the remaining ash after it has been burnt.
Materials
Cement production is environmentally unsustainable due to the high anthropogenic carbon emissions produced. Supplementary cementitious materials (SCMs), derived from the by-products of different industries, have been deemed an effective way to reduce carbon emissions. The reduction in carbon emissions is achieved by lowering the clinker factor of cement, through a partial replacement with an SCM. Sugarcane Bagasse Ash (SCBA) is produced as an agricultural waste from the sugarcane industry and has gained a lot of attention for being a feasible and readily available pozzolanic material, underutilised as an SCM. This study evaluates alkali-activated sugarcane bagasse ash’s mechanical and durability performance, at varied contents, in binary blended cement concrete and ternary blended cement concrete containing silica fume (SF). Potassium Hydroxide (KOH), used as the alkali activator, is intended to enhance the reactivity of the ash, with the possibility of a high-volume SCBA content. T...
The Mechanical Behavior of Sustainable Concrete Using Raw and Processed Sugarcane Bagasse Ash
Sustainability
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...
AN EXPERIMENTAL STUDY ON MECHANICAL PROPERTIES OF CONCRETE BY USING SUGARCANE BAGASSE ASH
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.
