Abstract：The recycled cement mortar is prepared by using the recycled sand of construction waste instead of natural sand, and the effects of different cement contents on the mechanical properties of recycled cement mortar are studied. The results of compressive strength and flexural strength of 3 d recycled cement mortar show that the compressive strength and flexural strength of recycled cement mortar are basically similar to those of common cement mortar, and all of them increase with the addition of cement content. Its 28 d compressive strength is 9.8 ～ 57.5 MPa, and the drying shrinkage goes up with the addition of cement content. The more the cement content is, the longer the drying shrinkage age is, and the drying shrinkage of recycled cement mortar is more than that of ordinary cement mortar.
