Key Points

The research aims to investigate the effects of curing temperature on the carbonation reaction of cement paste mixed with a CO2 fixing admixture.
Used CO2 fixing admixture containing γ-phase 2CaO·SiO2
Tested carbonation under different temperature conditions
Measured carbonation rate and calcium carbonate polymorph production
Carbonation rate increased slightly with temperature, but the difference was limited.
No significant temperature dependence observed for carbonation rate.
The amount of thermodynamically stable calcium carbonate increased with temperature.

Implication

Examines how curing temperature affects carbonation reaction in cement paste, suggesting limited temperature dependence.
