Durability analysis of partial replacement of ordinary Portland cement by white glass waste concrete

Abstract

Concrete consists of cement, water, fine aggregate, coarse aggregate, and air. The cement manufacturing process is responsible for a large carbon dioxide emission. Therefore, several researches have been conducted to find advantageous substitute materials, even if only partially. Waste glass emerges as an alternative because it is a non-biodegradable inert material, with a high recycling rate and low cost. Several studies on recycled glass as a partial substitute for cement in concrete have already been conducted in terms of workability, strength and properties, but few have reviewed the durability properties of concrete incorporating glass waste. It is a fact that durability is of great importance for the performance of concrete, because compromising it can lead to the emergence of pathologies. This article aims to carry out a study on the durability of concrete with the replacement of cement by glass waste, in order to verify its performance in relation to conventional concrete, identifying the advantages that attest to its use in civil construction as an alternative to concrete to be used in buildings, whether in new constructions or in the process of rehabilitation or maintenance.
