Parametric Investigation of Green Concrete for Optimal Utilization

Abstract

The research is focused on determine the ideal proportions and combinations of waste newlinematerials to enhance the mechanical properties and sustainability of concrete while newlineminimizing environmental and economic impact. In order to check the physico-chemical and newlinemineralogical behaviours of waste material, characterization of each and every waste material newlinehas been conducted by using standard methods. Si-O bonding, availability of CaO and sign of newlineagglomeration with pozzolanic properties in each and every sample implies their utilization in newlinethe concrete applications. The study employs a comprehensive testing regimen, including newlinevarious strengths, compaction factor and slump test to evaluate the performance of green newlineconcrete. newlineIt has been observed that Mix design of M 25 comprising of 10% WGP, 5% of SF in place of newlinecement and 20% FA, 10% of IW in replacement of sand and 5% of coconut shells as an newlinealternate to coarse aggregates provided higher compressive, flexural and split tensile newlinestrengths than the normal concrete for 7,14 and 28 days of curing period. The compressive newlinestrength after 28 days of curing period was observed as 44.78N/mm2 which is around 54% newlinemore than the strength produced by conventional concrete of grade M-25.The flexural newlinestrength that came from the tests after 28 days was 5.25 N/mm2 which is around 28% more newlinethan the normal concrete and the split tensile strength which was observed as 2.96 N/mm2 newlineis newlinealmost equal to the strength provided by the conventional concrete. So this mix is optimal, newlinecheap and can be applicable in construction sector. newlineThe results of this investigation contribute a deeper understanding of waste materials which newlinecan be effectively integrated into concrete mixes resulting better environmental and structural newlineperformance. newline
