An elaborate research foray on the strength parameters of concrete using glass powder, waste foundry sand and copper slag

Abstract

This research paper presents the design of concrete mix prepaid with Glass powder as fractional substitution of cement, Waste Foundry Sand (WFS) and Copper Slag as a fractional substitution of fine aggregates. Glass powder is a waste material obtained during polishing of glass. Generally glass is mainly composed of silica and when it is finely grounded into particle size less than 75 microns it exhibits pozzolanic reaction with cement and helps in formation of good secondary Calcium Silicate Hydrate (C-S-H) gel. Waste Foundry Sand (WFS) and Copper slag are obtained from foundry and copper industry. In this research work glass powder is partially replaced at five different substitution rates (5%, 10%, 15%, 20% and 25%) with cement, On the other hand waste foundry sand is replaced at (50%, 40%, 30%, 20% and 10%) and copper slag is replaced at constant percentage of 30% with fine aggregates. It was obtained that the strength parameter values of concrete having glass powder, waste foundry sand and copper slag is obtained maximum at concrete mixture of S4 containing 20% Glass Powder +20% Waste Foundry Sand and 30% Copper slag gives satisfactory results.
