β¦ Synopsis
A wide range of inorganic and organic admixtures have been investigated using isothermal conduction calorimetry. The results are presented as a series of maximum rate of heat evolution (Q max) versus reciprocal to peak height (i/t max) plots. Using equivalent molar concentrations of admixture under controlled conditions a comparative ranking system of inorganic and organic admixtures has been devised. Some general conclusions are drawn about the mechanism of action of accelerating and retarding admixtures.
