ELEVATED TEMPERATURE EFFECTS ON CONCRETE PRODUCED WITH RECYCLING AGGREGATE OBTAINED FROM CONCRETE SPECIMENS

Abstract

With the use of recycled aggregates (GDA) in concrete, it is aimed to protect natural aggregate resources, to reduce the demand for landfills, and as a result, to contribute positively to the environment in terms of sustainability. Except for the control group, during the concrete production phase, GDAs obtained from concrete wastes, which were subjected to 28-day strength test in ready-mixed concrete laboratories, were used as aggregate. GDAs were substituted for concrete by replacing 25%, 50%, 75% and 100% crushed stone aggregate. Within the scope of the experimental study, cylindrical samples of 100 mm x 200 mm dimensions were produced. The unit weights of the produced samples were determined. In addition, the compressive strength and capillary permeability results were determined after the samples were exposed to room temperature and temperatures of 100°C, 250°C, 500°C and 750°C. As a result, the use of GDAs produced from concrete wastes did not cause a significant decrease in the concrete compressive strength determined at room temperature. It was determined that the compressive strength results of the samples produced with GDA after high temperature (250°C, 500°C and 750°C) were higher than the kontrol sample.
