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.
