Summary: | This work is aimed at carbonation resistance of steel slag concrete based on maximum utilization of industrial waste residue. The investigation is conducted to study the carbonization resistance of concrete which containing steel slag aggregate (SSA), steel slag powder (SSP) and blast furnace slag (GSP). The ordinary concrete as baseline group, the other concrete are fabricated with the 25% SSA, in combination with 30% SSP and 20% GSP by total binder content. The microscopic properties are analyzed by XRD, SEM, micro-hardness tests etc. Experimental results indicate that the carbonation depth of concrete which adding 25% SSA, 30% SSP and 20% GSP, have lower carbonation depth significantly than the reference at 28 day and 56 day. The substitution of natural aggregate and cement are 25%, 50% respectively by industrial waste residue, that can improving microstructure of aggregate-cement stone interface, optimizing cementitious materials hydration environment, concrete presents better durability performance. |
