Abstract The problem of low disposal and utilization rate of bulk industrial solid waste needs to be solved. In this paper, a
high-activity admixture composed of steel slag-phosphate slag-limestone powder was proposed for most of the
solid waste with low activity and a negative impact on concrete workability, combining the characteristics of each
solid waste. The paper demonstrates the feasibility and explains the principle of the composite system in terms of
water requirement of standard consistency, setting time, workability, and mechanical properties, combined with
the composition of the phases, hydration temperature, and microscopic morphology. The results showed that the
steel slag:phosphate… More >
