Abstract

In order to explore the difference in the performance of recycled aggregate produced by different strength of parent concrete, six groups of test blocks with different compressive strength were used as parent concrete to prepare recycled aggregate, and relevant experimental analysis was carried out. The test results show that the higher the strength of the parent concrete, the higher the content of needle and flake in the recycled aggregate, and when the strength is greater than 40, the aggregate gradation does not meet the requirements of the specification; The water absorption rate of recycled aggregate increases first and then decreases with the increase of the strength of parent concrete (C25 ~ C55); The strength of the parent concrete increases, and the crushing value of the recycled aggregate decreases.
