摘要：The utilization of recycled aggregates can minimize environmental impact, and decreases the consumption of natural resources used for concrete applications. However, recycled aggregates are not suitable for use in the production of High Performance Concrete (HPC) due to their relatively high absorption capacity, instable properties and weaker strength. Such difficulties can be overcome through selection and partial substitution of aggregates. In this paper, recycled aggregates generated from demolished-construction wastes were selected and different perceptual were substituted through natural aggregates for application in the HPC. Results show that specimens containing partially recycled aggregates are optimum for producing normal strength recycled aggregates concrete.
