| Abstract: | Through optimizing the percent of coarse aggregate and sand, and using the 525# common silicate cement and compound high-powered water-reducer, the practicable high-strength concrete with the cubic compress strength of 75～85 MPa is mixed. The effects of the cement consumption, water-reducer, water cement ratio and the percent of sand on the performance of concrete mixture and mechanical properties of solid concrete are investigated. It may be used as research basis and references for mix proportion design of high-strength concrete. |
