Out of the various methods proposed for cutting down the amount of CO2 produced, mineral sequestration, where CO2 is chemically stored in the form of solid carbonates by the carbonation of minerals, provides a permanent and safe solution since the formed carbonates are thermodynamically stable with a large sequestration capacity available worldwide.
Reactive MgO hydrates at a similar rate to PC, thereby eliminating the expansion problems observed in the case of dead-burned MgO.
the increase in carbonation depth as the RH or the amount of water in the pore structure increases. The reduced permeability coefficient and lower diffusion rate in the case of lower water contents was studied by Powers et al.
The strength requirement for common commercially distributed masonry blocks is 7MPa.
relatively wet mixes with a w/c of 0.9 included pores saturated with water, thereby hindering the transport of CO2 through the samples and delaying the formation of HMCs, which eventually led to low UCS results within the presented time frames.
