Influence of the MB Value of Manufactured Sand on the Mechanical Property of Concrete

Abstract:

In this paper, influence of micro-fines on the manufactured sand and influence of manufactured sand containing micro-fines on concrete is studied. Using the MB value of manufactured sand to control the content of micro-fines in manufactured sand. The experimental results show that if MB value is less than 1.0, content of micro-fines is less than 15%, concrete keeps a high level of compressive strength ; both the content and property of micro-fines have a certain influence on the compressive strength of concrete; the fineness of micro-fines has influence on the early strength of concrete, but little influence on the later strength of concrete.
