| Abstract: | In this paper, the effect of binder content, sand ratio and limestone powder content on the working performance and mechamical performance of self-compacting concrete （SCC） with manufac- tured sand were experimental studied, the preparation technique of SCC was studied, and the drying shrinkage of SCC was measured. Test results showed that the working performance and mechanical per- formance of SCC could satisfy the requirement of highway project, and the addition of limestone powder could improve the drying shrinkage of SCC. |
