Experimental study on compressive strength of manufactured sand concrete

Abstract. Compressive strength is one of the important mechanical properties of conerete, and the indicator of compressive strength of manufactured sand concrete is more important to be promoted. This paper presents the results of the compressive strength tests on concrete specimens using the manufactured sand, the replacement ratios of manufactured sand by mass to the natural sand are 0, 30%, 50%, 70 % and 100 % respectively. The optimum replacement ratio the concrete is suggested. This could be used as a reference for the applications of the concrete using the manufactured sand in engineering
