Ychwanegu Tag | Crynodeb: | The purpose of this research is to address the significant pollution problem generated by construction waste, particularly demolition and debris generated in cities, by applying the reuse of these materials to decrease the volume sent to landfills and contribute to a sustainable construction model. To achieve this, the percentage of recycled concrete aggregate that can be partially replaced with coarse natural aggregate and its influence on compression strength was determined. Recycled concrete was collected from tested cylinders, and sidewalk waste, among others and the aggregate properties were determined according to INEN and ASTM standards. Subsequently, the dosing was carried out by the Optimum Density Method for a strength of 210 kg/cm2 with replacement percentages of recycled aggregate ranging from 10, 15, 30, 60, and 100% according to the weight of the coarse aggregate. Concrete specimens were also prepared in the traditional way to compare their strength. Therefore, it was identified that compression strength decreases as the amount of recycled aggregate increases, demonstrating that replacements with percentages lower than 30% are feasible since 10% and 15% show favourable design values of 214.54 and 211.57 Kg/cm2 at 28 days. |
