Wollastonite is a naturally occurring mineral that is a chemical combination of calcium, silicon and oxygen. Wollastonite is formed when limestone or other high-calcium rocks undergo high temperature and pressure changes sometimes in the presence of silica-bearing fluids such as in skarns or contact metamorphic rocks.
Huang et al. (2019) has shown numerically that cement which is partially replaced by wollastonite in CO 2 cured 1 m 3 of cement block has Global Warming Potential (GWP) of 292 kg- CO 2 eq. compared to steam cured ordinary Portland cement block has GWP of 419 kg- CO 2 eq.. This result was found with a 20% replacement of wollastonite; with higher wollastonite …
