Strength and Workability Studies on Slag Sand Concrete Blended with Flyash and Glass Powder

Abstract

The depletion of naturalresources and the environmental impact caused by conventionalbuilding materials have led to the exploration of sustainable alternatives. The use of industrial wastes and its by-products in the construction industries has becomewidely popular in recent yearsbecauseof their beneficial propertiesand potential for reducing the environmental impact. This study investigates the effects of fly ash,glass powder and slag sand in M30 grade concrete.In this process, cement is partially replaced by flyash at a percentagesof 0,10,20 and 30% and addition of glass powder at a percentage of 0,10 and 20%.This eco-friendly concrete was made using slag sand instead of natural sand. The main objective of this research is to evaluate the mechanical properties of slag sand concrete with various combinations of cement, flyash and glass powder. In order to evaluate the concrete specimens' performance, strength and workability tests were conducted on them. The hardened properties,including compressive strength were assessed after a curing period of 28days and 90 days,whilesplit tensilestrength and flexuralstrength were assessed after curing period of 28days. The results are encouraging in producing sustainable M30 grade concrete.
