On early Mechanical Properties of Artificial Sand Concrete

Abstract:

This paper studies the early mechanical properties of artificial sand concrete, we found by comparison with natural sand concrete that the slump of artificial sand concrete were increased by 85%, and the strength 0f 16h and 1d and3d were increased by 23.4% and 20% and 11%. Therefore, artificial sand can significantly improve the workability of concrete mix, improve the early strength of concrete. It has guidance significance to the early strength of concrete engineering.
