Abstract

Abstract

The strength of recycled concrete was studied whose recycled coarse aggregate was preprocessed by DSP grout. At the same time,the strength of recycled concrete added DSP grout as part of the concrete directly in the mixing process was also studied,but also with a comparison of the basic recycled concrete. The results show that for the cube compressive strength and prism compressive strength,the strength of recycled concrete improved by DSP grout is the highest,respectively,increased by 25. 6% (or 26. 7% ) as compared to the prism compressive strength of the basic recycled concrete. And for DSP grout pretreatment recycled aggregate concrete,7 d cube compressive strength is higher than the basic recycled concrete,28 d cube compressive strength is lower than the basic recycled concrete, 28d prism compressive strength is high and low. In addition,the failure mechanism of the recycled concrete is analyzed.
