An Investigation of Cement Mortars Containing Glass Powder as A Partial Cement Replacement

Abstract

Lately, because of the pollution caused by cement production waste materials that can be used instead of cement aroused interest by researchers. Glass is one of these waste materials. Glasses due to their nonbiodegradable properties, cause serious environmental risks and recycling this waste material would minimize these environmental concerns. Therefore, finely granulated glass powders, due to their high silicious content are being used as pozzolanic admixture. In this study, glass powders are replaced with cement (by weight) at 0%, 5%, 10% and 15%. And mechanical and durability performances are investigated. Compressive and flexural strength, flow test, abrasion resistance, sulfate resistance and capillary water absorption test were conducted. Results indicated that an increase in glass powder dosage in cement mortars leads to decrease in mechanical properties.
