| Sumario: | Nowadays considering the growth of the population and increasing the need for housing, construction activities have been booming more remarkably than the past. So, the volume of construction waste has increased which has caused many environmental problems. These derbies have potation to reuse in construction activities. Recycling is one of the best ways to manage this debris. Because it reduces the volume of waste. It also confirms to reusing, and it reduces the need to extract and uses natural resources. Considering the importance of this, this waste can be used as replacement of aggregates in concrete. In this study, the effect of different percentages of replacement of construction and demolition waste as coarse aggregate on mechanical properties of concrete has been investigated, and the effect of using these debris on compressive strength, tensile strength and flexural strength concrete was studied. The percentages of replacement are 0%, 10%, 20%, 30%, and 50%, and the water to cement ratio is 0.49. Tests were done for two curing time 7 and 28 days. Also, in order to analysing the results, statistical analysis of one-way ANOVA was carried out. The results show that with increasing the replacement rate, compressive strength, tensile strength and flexural strength are decreased, but these decreases aren’t significant |
