Abstract：Steel slag concrete with nano-SiO2 is a new environment-friendly building materials,compressive strength and split-ting tensile strength of concrete were studied based on different content of steel slag and different type of nano SiO2. The change rule of mechanical properties of steel slag concrete with nano SiO2 was achieved. The test results show that the 28 d compressive strength and splitting tensile strength of steel slag concrete reaches the maximum value with 20% dosage of steel slag,which were 38.4 MPa and 2.54 MPa;the nano SiO2 could effectively improve the steel slag concrete compressive strength and splitting tensile strength;according to the ability of improving the strength of concrete,the order of three kinds of nano SiO2 from large to small in turn is:SP15>SP30>SP50;the compressive strength and splitting tensile strength of steel slag concrete with nano-SiO2 reached the maximum with 30% dosage of steel slag.
