초록

γ-dicalcium silicate (γ-C2S) is characterized by its strong carbonation reactivity and has the prospect to be utilized as a building material with the added benefit of CO2 capture. This paper aims to point out the impact of γ-C2S on the microstructure characteristics and mechanical properties of GGBFS paste, and mortar samples. Three curing conditions including un-carbonation, natural carbonation, and accelerated carbonation were applied to the research. Besides, hydration products after the carbonation process are also detected. What's more, the carbonation treatment method also meets the requirement of capture more greenhouse gas and recycles the waste products of metallurgy.
