Hydration of blended cement with high alite content

Abstract

We have produced a trial high alite cement in a cement plant and have researched the hydration reaction of the high alite cement with blended materials. The high alite blended cement has a higher heat of reaction and produces a more hydrated product than ordinary Portland cement, as confirmed by heat liberation from a calorimeter. The amount of Ca(OH)₂ (or CH) was confirmed to be higher than that of ordinary Portland cement. In this research, we focused on measuring the properties of blended high alite cement in the early hydration period. Results were obtained for hydrated samples at up to 28 days to ascertain the possibility of using high alite cement and its potential improvement in blending.
