Influence of Machine-Made Sand Performance on Concrete

Abstract

This paper studied the influence of various performance indexes of machine-made sand on concrete work performance and admixture adaptability. The experimental results show: The MB value of machine-made sand has obvious negative effects on concrete performance and admixtures. The rock-powder content and the fineness module have relatively little influence on the working performance of concrete. The negative effect can also be reduced by adjusting the sand ratio, but the amount of external additives has a certain influence.
