Experimental Study on the Cubic Compressive Strength of Recycled Sand Concrete

Abstract

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