The Effect of Waste Marble Powder on the Engineering Properties of the Brick in Kırşehir Region

Abstract

In this study, it is aimed to investigate the usability of waste marble dust from Kırşehir region in the production of environmentally friendly bricks. In line with this goal, it is aimed to produce environmentally friendly bricks with superior physical and mechanical properties compared to normal bricks by using waste marble dust. Within the scope of the study, blended brick was produced by substituting waste marble dust extracted from Kırşehir region at the rates of 10%, 20%, 30%, 40% and 50%. The water-saturated unit weight, porosity, water absorption (by weight), freeze-thaw effect, sulfate effect, compressive strength and bending tensile strength tests were performed on the produced samples. As a result, with the increase in the amount of waste marble dust, a decrease was observed in the saturated unit volume weight, while the values of porosity, water absorption (by weight), freeze-thaw effect and sulfate effect increased. In the mechanical tests, it was determined that while the compressive strength decreased, the tensile strength value increased in bending. In addition, it was concluded that appropriate amounts (10%) of waste marble dust substitute can improve brick properties.
