| Abstract: | Aiming at the main problems in application of RPC,i.e.,high production costs and energy consumption,steel slag powder(SS) as well as ultra-fine fly ash(UFFA) and silicon fume(SF) were used as reactive powder component to product RPC,and meanwhile,fine river sand was used as aggregate instead of quartz sand.The influence of the composition of cementitious materials,i.e.,the dosage of SS,the total dosage of and the dosage ratio of SS and UFFA were investigated.The results showed that RPCs whose compressive an... |
