The Influence of Sand Ratio on Concrete Performance in the Case of Fixed Powder Paste

Abstract:

In the case of fixed powder paste, changes in the sand ratio have an impact on the workability of concrete. According to Mehta and Aitcin’s ideas for the preparation of HPC, regard the powder as cementing material and the powder paste as cementing material paste. Investigate the influence of sand ratio on concrete performance when the powder paste reaches the fixed number 350L, the concrete optimum performance. When the sand ratio is 37%~41%, in the case of causing minimal impact on the strength, you can get optimum workability of concrete.
