Using glass wastes and bentonite to produce a new ceramic tile

Abstract

This paper discusses the recycling of glass waste as a compound in the production of ceramic tiles. The present study aims to investigate the effects of glass waste (with two different granulometries) on the physical and mechanical properties of ceramic tiles, in order to demonstrate their suitability for the production of ceramic materials. A series of ceramic tiles was prepared based on bentonite (B) by adding 70, 65, and 60 wt% glass wastes (GW1 and GW2 with two different granulometries) into the batch composition. The ceramic tiles were sintered at a constant temperature of 900 °C following the same production protocol. The physical-mechanical properties and chemical durability of all ceramic tiles produced were evaluated. The results show that ceramic tiles can be produced from a basic mixture of 35% bentonite and 65% glass waste, with good physical, mechanical, and thermal properties (the local Algerian bentonite is considered a clay binder and has excellent plasticity).
