Application Of Zeolitized Glass Powder In Cement-Based Materials

Rational use of waste by applying new technological solutions can significantly reduce energy consumption and emissions into the environment. This article presents the research of colourless ground waste glass used as a substitute for Portland cement. Glass powders were zeolitized to improve the pozzolanic properties of the material. Research showed that hydration temperature and compressive strength of the specimens with 5 and 10% of the cement replaced by zeolitized admixture is similar or higher compared with the specimens where non-zeolitized glass powder is used. To summarise, it can be concluded that zeolitization of ground glass powder is feasible only in the production of specialized concrete products.
