Abstract

In this study, certain mechanical behaviors of concretes that were added e-waste instead of fine aggregates under high temperature were investigated. The total binder was kept constant at 340 kg / m3 and the water / binder ratio was 0.51 in all mixtures. Cocnrete samples in which e-waste were substituted for fine aggregate in the ratios of 5%, 10%, 15% and 20% by weight were produced as well as control samples that do not contain e-waste so that a comparison could be performed. Cube concrete samples produced with the dimensions of 15x15x15 cm were subjected to standard hydropathy for 28 days, and then each sample was weighed for unit weight. After the samples were exposed to different temperatures, compressive strengths, bending tensile strengths were measured and water and water volume tests were performed. The samples produced were subjected to 100 ° C and 500 ° C temperature effects including the room temperature (25 ° C). As E-Waste ratio increases, compressive strength decreases. The observed decrease in strength increases with increasing temperature. Tensile strength increases as the E-Waste ratio increases, while the compressive strength ratio of the compressive strength increases as the E-Waste ratio increases. This shows that E-Waste increases the ductility even if the material pressure decreases. Unit Weights are measured each time E-Waste ratio increases and unit weights decrease. Water absorption rates by weight and volume were measured according to the TS 12390-7. Water absorption by volume and weight increases with the e-waste ratio.
