Waste management in the world has come to the fore in recent years. Like many materials used as alternative raw materials, glass waste has become an increasingly important situation. It is very important in terms of sustainability that these wastes are used as alternative raw materials in the production of new materials for various industries. Recycling of glass, which is produced and consumed in a wide range, contributes to many different sectors. For this purpose, the use of materials obtained in two different forms, namely powder and fiber produced from waste glass, in cement mortars was investigated. There are three factors, including glass powder (GP) amount with four levels of 0, 45, 90 and 135 g, glass fiber (GF) amount with two levels of 0 and 13.37 g, and curing period (CP) with three levels of 7, 28 and 56 days. Compressive, flexural strengths and abrasion resistance of cement mortar samples were determined. In addition, acceptable regression models were derived by using multiple regression analysis. Analysis of variance (ANOVA) showed that the effects of all three factors on the mechanical properties and, GP and CP factors on abrasion resistance of cement mortars are significant. Improvements in mechanical strength and abrasion resistance were observed in the use of glass fiber and glass powder added cement mortars produced at appropriate rates. The study shows that the use of glass fiber and glass powder separately or together in the production of cement-based materials such as concrete, which is exposed to abrasion, is beneficial. As a result, the properties expected from the produced concrete will be met. The use of glass waste will contribute to the realization of an economical and environmentally friendly concrete production. |
