摘　　要：为解决锰渣和蛋壳对环境造成的污染问题,为实现锰渣和蛋壳资源的回收利用。本文对锰渣和蛋壳粉对混凝土的力学性能的相关影响进行了实验探究。在保证混凝土抗折抗压强度均大于对照组的情况下,实验得出了混凝土中可掺入的锰渣和蛋壳粉的最合适掺量:锰渣复合蛋壳粉掺入时,因养护龄期的不同,蛋壳粉的最佳掺量分别为3%和5%;蛋壳粉掺量为0时,锰渣的最佳掺量为5%,最大掺量为10%。In order to solve the environmental pollution caused by manganese residue and eggshell,it is necessary to recycle manganese residue and eggshell resources.In this paper,the effects of manganese slag and eggshell powder on the mechanical properties of concrete are experimentally investigated.Under the condition that the flexural and compressive strength of concrete is greater than that of the control group,the optimum content of manganese slag and eggshell powder inconcrete is obtained by experiment:when manganese slag composite eggshell powder is added into concrete,the optimum content of eggshell powder is 3%and 5%respectively according to different curing ages;when the content of eggshell powder is 0,the optimum content of manganese slag is obtained 5%,and the maximum content is 10%.
