Possibility of using waste glass powder and ceramic tile as an aggregate on the flexural behavior and strength properties.

Abstract

The study discusses the results of the experiment carried out about the effects of incorporation of waste ceramic tiles aggregate combined with waste glass powder on the performance of cementations mixtures. Crushed gravels in concrete mixes were replaced by ceramic tile (CT). Their ratios were 15%, 30%, 45%, and60%. On the other hand, glass powder was used to replace fine aggregate at a percentage of 15%, 30%, and 45%. Ten different forms of concrete incorporated waste ceramic and glass powder was designed and prepared. The mixtures were examined in their fresh and hardened states in terms of workability, density, compressive, tensile strength, and flexural beam tests. The water/binder ratios and cement content of all mixtures remain constant. The results pointed out that by applying waste glass powder in concrete mixture that contained waste ceramic tiles have enhancement the strength properties. Additionally, both waste materials are considered as a good potential for integrating them in the concrete mixture as compared to the conventional concrete. As a corollary, the best result was obtained with a mix containing 25% glass powder and 15% ceramic tile. These alternatives have many benefits environmentally, economically and show positive effects on the characteristics of concrete mixtures.
