ACI 212.3R-10 Report on Chemical Admixtures for Concrete
Calcium chloride should not be used with calcium aluminate cement because it often retards the hydration of the aluminates. Similarly both calcium chloride and potassium carbonate retard the setting time and decrease the early strength development of rapid-hardening cements based on calcium fluoroaluminate (C 11 A 7 -CaF 2 ).

Quicklime–both high calcium and dolomitic is extensively used as a flux in purifying steel particularly removing phosphorus sulfur and silica and to a lesser extent manganese in the electric arc furnace (EAF) and basic oxygen furnace (BOF). Slags consist of a mixture of silica calcium oxide magnesium oxide and aluminium and iron oxides.

Numerical Data for Some Commonly Used Solid State Reaction
Many solid state reactions can be represented by equations of the type F(α) =kt where α is the fraction of material reacted in time t. These equations can be expressed in the form F(α) =A(t/t 0.5) where t 0.5 is the time for 50 reaction and A is a calculable constant depending on the form of F(α).

Blends of ordinary Portland cement (OPC) and calcium aluminate cement (CAC) exhibit a very fast setting over a wide range of OPC/CAC ratios. Figure 1 shows a typical example of such behavior but the exact setting time will also depend strongly on the characteristics of the individual cements employed and on the water/solid ratio of the mix.
