Impact of construction & demolition waste and slag sand on the properties of high strength self - compacting concrete

Abstract

This Research mainly focuses to explore the characteristics of High Strength self-compacting concrete developed using industrial waste steel slag sand and construction demolition waste. The purpose of this study is to examine both rheological and hardened properties by incorporating steel slag sand and C&D waste as a substitute to M−Sand in different proportions along with comparison of the three sands in equal quantities. The test results exhibited good flow ability, passing and filling abilities for all the combinations adopted which satisfied the EFNARC Guidelines. The results showed that compression, split-tensile and flexural strength of High-performance self -compacting concrete has declination with higher percentages of steel slag sand and C&D Waste. The maximum declination was observed at complete replacements of slag sand with respect control mix. Utilization of adopted materials in equal proportions exhibited promising results compared to control concrete and this can be considered optimum.
