Expansion characteristics of a compounded-expansive additive and pre-hydrated high alumina cement based expansive additive
The expansion characteristics of a newly developed compounded-expansive additive (CEA) and a pre-hydrated high alumina cement based particulate expansive additive are reported. Effect of temperature during pre-hydration and drying of high-alumina cement is studied. The quick setting mechanism and volume stability of expansive cements containing different types of expansive additives are also discussed. It is apparent that high temperature treatment, an integral step in the production of pre-hydrated high alumina cement, will significantly reduce the expansion value and delayed expansion development. The compounded-expansive additive has desirable expansion characteristics with potential industrial application.
