Mechanism of interaction between hydration–carbonation of C2S
The physical and microscopic properties of γ-C 2 S and β-C 2 S under hydration, carbonation , and hydration–carbonation cycle reactions were investigated. The hydration–carbonation cycle reaction facilitated the carbon sequestration of C 2 S, and the generation of CaCO 3 filled the pores of the matrix and enhanced the matrix density in the carbon fixation reaction process. In the subsequent hydration and reaction process, the formation of hydration products increased the number of pores in the matrix and reduced the matrix density. Post-hydration, γ-C 2 S slurry became powder and had no mechanical strength . However, after carbonation reaction and two carbonation–hydration cycles, γ-C 2 S exhibited better mechanical properties than β-C 2 S.
