An Experimental Study on the Engineering Property and Durability of Concrete With Replacement Ratio of Crushed Sand

Recently, Trouble of sand supply is occurred according to exhaustion of natural sand resources. therefore, various measures are proposed for solution of trouble of sand supply also the government settled trouble of sand supply through application of crushed sand. but because both crushed sand are poor against general sand, they lead to lowering of qualify of ready-mixed concrete. Therefore, this study evaluated engineering property and durability of concrete using crushed sand and applied evaluation result to fundamental data for quality control of concrete using crushed sand. The results of this study have shown that quality of concrete using crushed sand independently is poor against general concrete. but, the workability, compressive strength and durability of concrete mixed crushed sand with genera can improve on those of concrete used general sand.
