A novel method to produce a ceramic paver recycling waste glass
Abstract
The present work studies the incorporation of the waste glass in ceramic paver, containing clay, one plentiful raw material in the earth’s crust. Ceramic paver has a huge capacity of use and, consequently too, of recycling of the waste glass. A more sustainable process is presented here, since there is the use of waste which give more energy efficiency during ceramic firing, because of the fluxing protagonism of the waste glass. Formulations using clay up to 60% by weight of the waste glass were evaluated. The pressing method is used to produce pavers for its firing in temperatures between 900 and 1000 °C. As a main result, the waste glass acts as fluxing in formulations, improving pavers properties. Pavers produced at 900 °C present properties for application in industrial floors, light vehicular and pedestrian traffic, and when fired at 950 °C, are suitable for use in heavy vehicle traffic. The waste glass makes it possible to produce novelty ceramic pavers with high properties from lower firing temperatures when compared to formulations without waste glass.
