    Abstract

    Calcium chloride (CaCl2) is a well-known accelerator of the hydration of concrete. Its activity is very complex, and a meaningful mechanistic interpretation requires an assessment of the effect of CaCl2 on each of the individual clinker mineral components. This paper reviews the considerable literature associated with hydration acceleration of calcium silicates, aluminates, and ferrites in the presence of CaCl2. It attempts to cover all of the most meaningful data and observed effects and to relate these effects to various proposed mechanisms. Where appropriate, the reviewed work is critiqued, and suggestions for potentially important new fields of research are offered.
