Like in reaction ii the calcium silicate hydrates contribute to the strength of the cement paste. This reaction generates less heat and proceeds at a slower rate meaning that the contribution of C 2 S to the strength of the cement paste will be slow initially. This compound is however responsible for the long-term strength of portland cement concrete.

Portland Cement Hydration An Overview Sciencedirect

Portland Cement Hydration An Overview Sciencedirect

Portland cement hydration results in the formation of a large amount of portlandite 20–30 of the hydrated mass of cement according to the respective amounts of C 3 S and C 2 S in the clinker. In concretes having a high wc this portlandite appears in the form of large hexagonal crystals as shown in Figure 3.12. These portlandite crystals have a marginal impact from a mechanical point of view so

Investigation Of The Co2 Sequestration By Indirect Aqueous

Mineral carbonation of CO2 with fine-grained waste cement was investigated using NH4Cl as a recyclable extracting agent. The amount of calcium extracted with NH4Cl was not as high as with more commonly used extraction agents such as HCl and CH3COOH. NH4Cl also exhibited high selectivity in the calcium extraction process such that calcium ions comprised over 99 of the leaching solution.
