Abstract

Through benchmark concrete proportion to material composed of adaptability and efficiency test, add special preparation of concrete admixture, mechanism of different stone powder content of sand sand mechanism of C55 high performance concrete performance impact study. The test results show that the special additive for different stone powder content adaptability is stronger, the mechanism of sand preparation by 28 days compressive C55 concrete compressive strength of 70 Mpa, the air content is 3%, satisfies the requirement of pumping.
