Preparation and application of the cement-free steel slag cementitious material

In order to utilize the steel slag effectively, the steel slag, compound agent, fine sand, gravel and admixture are used to prepare cement-free steel slag cementitious material. The compressive strength of the mortar can reach 70 MPa. The performance tests are conducted on the C50 grade of the material. The experimental results indicate that the relative dynamic modulus of elasticity maintains at 66% and the mass loss is 1.1% at 300 cycles, so...
