为探索锂渣掺量、再生粗骨料掺量以及龄期对混凝土抗拉性能的影响规律，采用标准立方体试件进行劈裂抗拉试验研究．结果表明，在再生混凝土中掺入锂渣可以有效提高其抗拉强度．当再生粗骨料掺量为70%，锂渣掺量为15%时，28 d的混凝土劈裂抗拉强度最大，较同龄期下未掺入锂渣的普通混凝土的抗拉强度增加了57.40%．

In order to explore the impact of the lithium slag content, recycled coarse aggregate content and age on tensile properties of concrete, we have a test study on specimen splitting by using standard cube. The results show that the recycled concrete which incorporated lithium slag can effectively improve the tensile strength. When the recycled coarse aggregate content is 70%, the lithium slag content is 15%, the splitting tensile strength of 28 d concrete is the largest, increased by 57.40%than the tensile strength of the ordinary concrete which is not incorporated lithium slag in the same age period.
