摘　　要：为研究锂渣掺量对混凝土相关力学性能的影响,开展了单掺锂渣混凝土的抗压强度和抗折强度试验。结果表明:掺入锂渣能改善混凝土的密实性,锂渣起到了较好的填充作用;混凝土试件养护28 d后,其抗压强度和抗折强度随锂渣掺量增加而呈现出先增后减的变化趋势,且锂渣掺量为20%时混凝土试件的力学性能发挥最佳。基于试验数据,建立了锂渣混凝土抗折强度和抗压强度之间的关系式,供工程应用参考。This experiment is to study the effect of lithium residue on the mechanical properties of concrete,and the compressive strength and anti-compensation test of single doped residual concrete were carried out.The results show that during lithium residue can improve the conflict of concrete,lithium slabs have played a better filling effect.After 28 d of condensation,the compressive strength and flavoring of the resistance and the resistance to increase the change in the increase of the lithium residue trend,and the mechanical properties of concrete test pieces when the lithium residue is 20%.Based on the test data,a linear regression model was established between the flexural strength and compressive strength of lithium slag concrete.
