Research on the Intensity Formula of Recycled Concrete Based on Crushed Index

Abstract:

In order to obtain the intensity formula of recycled concrete, effects of crushed index of recycled aggregate, crushed index of natural aggregate and replacement rate of recycled aggregate on compressive strength of recycled concrete are discussed in this paper. Based on the results of recycled concrete with different replacement rate of recycled aggregate, the intensity formula of recycled concrete is proposed. It can provide references for engineering applications.
