Abstract
To decrease the cement and SF content of RPC by using ultra-fine fly ash (UFFA) and steel slag powder (SS), the effect of these mineral admixtures on compressive strength of RPC were investigated. The experimental results indicate that the utilization of UFFA and SS in RPC is feasible and has prominent mechanical performance. The microstructure analysis (SEM and TG-DTG-DSC) demonstrated that the excellent mechanical properties of RPC containing SS and UFFA were mainly attributed to the sequential hydration filling effect of the compound system.
