Enhancement of high temperature performance of cement blocks via CO curing.

Carbonation for the curing of cement-based materials has been gaining increased attention in recent years, especially in light of emerging initiatives to reduce carbon dioxide (CO) emissions. Carbonation method or CO curing is founded on the basis of the reaction between CO and cement products to form thermally stable and denser carbonate, which not only improves the physical and mechanical properties of cement-based materials, but also has the ability to utilize and store CO safely and permanently. This study aims to assess the effect of CO curing technology on the high-temperatures performance of cement blocks.
