characteristics of the individual cements employed, and on the water/solid ratio of the
mix. After setting, the OPC+CAC blend exhibits rapid strength development, and
measurable strength values may be achieved within less than 1 hour. The final strengths,
however, are lower than those of either the Portland cement or the calcium aluminate
cement alone. Figure 17.2 shows typical strength development of OPC+CAC blends as a
function of their composition.
