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.
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.
Effect of Sugarcane Bagasse Ash as Partial Replacement of Cement on Mortar Mechanical Properties
Brazil being the most producer of sugarcane in the world, this commodity plays an important role in the country economy, especially in its northeastern region. The most attractive waste from sugarcane industry is its bagasse, which can be used in several manners. One of these ways is the electric energy cogeneration, a process that involves burning at high temperatures operations often producing a significant amount of waste referred as sugarcane bagasse ash. This type of ash is also generated in pizzerias that uses this material replacing the wood in its ovens. Recent researches indicates that the major chemical component of such ash is the SiO2 that exhibits great potential to be used as a mineral addition in concrete or mortars. The main objective of the research is to analyze the potentialities of using sugarcane bagasse ash come from sugarcane industry and pizzerias as a partial substitution of Portland cement to produce mortars. The mechanical properties of interest were the c...
Suitability of Sugar Cane Bagasse Ash as a Replacement for Cement in Concrete
International Journal of Advances in Scientific Research and Engineering (ijasre), 2019
This study is aimed at investigating the compressive strength of concrete using Sugarcane Bagasse Ash (SCBA) as a replacement for cement in concrete using two grades of concrete; grade 20, and 30 respectively. Sugarcane bagasse ash is the waste product of the combustion of bagasse for energy in sugar factories and is also by-products of agricultural waste, sugar cane bagasse ash are disposed of in the landfill and are now becoming an environmental concern. The concrete cube cast was; control (0%) 2%, 4%, 6% and 8% respectively, the cube was cast, cured and tested at 7days, 14days, and 28days. Although the results of this study have shown a significant reduction in compressive strength of concrete utilizing SCBA than normal concrete, it can be concluded that optimum amount of sugarcane bagasse ash that can be replaced with cement is 6% by weight without any admixtures.
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.
Characterization of Compressive Strength of Concrete Blended with Sugarcane Bagasse Ash
2015
A number of researchers today are focusing on ways of utilizing either industrial or agricultural waste as a source of raw materials for production of construction products. Presence of silica in Sugar Cane Bagasse Ash (SCBA) contribute to improved Pozzolanic activity, but the silicate content may vary from ash to ash depending on the burning conditions of bagasse and the properties of soil on which the sugarcane is grown. The main objective of this research was to characterize the compressive strengths of concrete by varying the SCBA and (Ordinary Portland Cement) OPC contents. The SCBA used for this research was sampled from Nzoia Sugar Company (NSC), one of the key players in Kenya’s Sugar Industry. The two variables; cement and SCBA content were applied to establish the concrete’s workability and compression strength at different curing periods (7, 14 and 28 days). Non-probability technique of sampling, specifically purposive sampling was applied in selecting the units that was ...
