Heats of hydration and pozzolan content of portland-pozzolan cements
Journal of Research of the National Bureau of Standards, 1952 Methods are described for the measurement of the approximate heat of solution in acid of portland-cement^-pozzolan mixtures. Examples are given of the estimation of the heat of hydration of portland-pozz olan cements. Determinations of the amount of material undissolved in the calorimeter, as well as the heats of solution, were applied to the problem ...
