Abstract
Glass, who is found as a waste in nature, seems to be among the causes of fires in forest areas and landfills, especially with the increase in temperature in recent years. Within the scope of the study, waste soda glass bottles collected from waste sites and natural environment were separated by passing through 0.25-0.5 mm sieves after grinding. The self-compacting concrete (SCC) produced with this glass sand were replaced with the natural sand inside. Natural sand and glass sand were substituted in increments of 5% between 5% and 35% by volume. SCC were tested with fresh feature tests where it provides regulatory standards. Stress-strain relationships were obtained for 7- and 28-days old samples from the mixtures obtained. These relations were evaluated by comparing them with the concrete model, which is frequently used in the literature. It was observed that the resulting stress-strain relations converged well to the model chosen especially at the age of 7 days but diverged from the model used at the age of 28 days, especially in the initial part.
