Abstract

This study aims to investigate the effect of incorporating waste glass powder (WGP) and quarry waste sand (QWS) on the properties of eco-friendly self-compacting mortar (SCM). Ordinary cement was replaced with WGP at rates of 0%, 10%, 20% and 30% by weight and the properties of the QWS-based SCM are compared to those of natural sand (NS)-based SCM. In this study, slump flow, superplasticizer requirement, mechanical strength, rheological parameters and hydration heat were investigated. The results obtained show that the use of WGP with different types of sand mixtures increases the fluidity of the SCM. After curing, SCM with 10% WGP exhibited higher compressive and flexural strengths after 28 days for both type of sand. The best performance was obtained with SCM mixes prepared with QWS sand compared to that of NS sand. Adequate relationships have been established to predict slump flow and mechanical strengths as a function of test parameters with high correlation coefficient and low root mean square error.
