Research on Properties of Recycled Coarse Aggregate

Abstract:

The performance of recycled coarse aggregate has significant effects on recycled concrete. The performance of recycled coarse aggregate were tested according to Recycled coarse aggregate for concrete (GB/T 25177-2010). The Result showed that the recycled coarse aggregate grading in accordance with regulation requirements, and compared with the natural coarse aggregate: high powder content and water absorption, low needle and plate particle content, low apparent density, compression capability as low as soundness. And the property of recycled coarse aggregate after cleaning has the performance of guaranteeing the quality by using. Through the test results and consult the national regulation, the recycled coarse aggregate in Xinjiang can be preliminary division to the categories of I and II.
