Effects of Micro Fines Content on Workability and Mechanical Properties of Manufactured Sand Concrete

Abstract

Natural sands are gradually depleted and manufactured sand concrete in engineering is becoming increasingly important. However, manufactured sands generally have the higher micro fines content, which limits wide applications of manufactured sands. This paper aims to study the effect on the Stone powder content on concrete workability, compressive strength, flexural strength. Results show that manufactured sand concrete mixed with a certain percentage of stone powder can improve the workability and mechanical properties. When mixed with 13% of Stone powder, manufactured sand concreted shows the best performance.
