Effect of Sugarcane Bagasse Ash on bagasse fiber reinforced concrete properties
As one of most consumed resources in the planet, different new technologies are highly being implemented recently to enhance both fresh and harden properties of concrete. Insertion of fibers, use of admixtures and utilization of substituting materials are among the technologies being exercised to create special concrete contributing to improve strength and setting time properties which in turn helps to reduce environmental and economic impacts faced while working with concrete. Bagasse fiber-reinforced concrete is one type of special concrete that can be made by way of inserting well-prepared bagasse fiber in to a concrete mix to enhance the tensile properties of concrete. But researchers found that, its utilization reduces compressive strength although the condition might be adjusted using a mineral admixture. The general objective of this study was to assess effects of sugarcane bagasse ash on fresh and harden properties of bagasse fiber-reinforced concrete. This experimental study carried out preparing five different mixes to check compressive, split tensile and flexural strength tests after each 7, 14 and 28 days of curing. For this study, cement replaced by weight with bagasse ash in 5%, 10% and 15%. The effects of each percentage mix have finally been compared with FRC mixture with constant 0.5% sugarcane bagasse and conventional C- 35Mpa concrete. Economic analysis for best mix has also been one of the objectives for study undertaken. Result of the research shows that, among fiber reinforced concrete mixtures, maximum strength of harden concrete achieved from M2 i.e. a mix with 5% replacement level and incorporation of 0.5% bagasse fiber. based on the investigation, 19.6%, 6.05% and 6.67% more strength have succeeded for computed compressive, split tensile and flexural strength tests respectively at 28 days of curing by this mix relative to control FRC mix with only 0.5% bagasse fiber content. Similarly, the tensile and flexural strength of M2 shows an increment resulting further 15.27% and 13.33% computed value at 28 days of curing with respect to M1 despite a slight reduction in compressive strength as compared with conventional concrete M1. And based on economic comparison, preparation of ordinary concrete mixture takes additional 0.61% increase in price than cost incurred to prepare B.F.R.C. with 5% bagasse ash to replace cement.
