Experimental study on replacement of fine aggregate by gold tailings for concrete preparation
Based on the standard concrete mix ratio,gold tailings are used to replace fine aggregates in the preparation of concrete,and the compressive strength and flexural strength of concrete are tested.The results show that the effect of gold tailings replacement rate on concrete strength is non-linear,and there is an optimal replacement rate between 20%and 30%.When the replacement rate of gold tailings is between 10%and 30%,the strength of gold tailings concrete is higher than that of concrete without gold tailings,which meets the relevant standard requirements.
