Abstract:
Two methods of estimation of 7- and 28-day heats of hydration of portland m e cement from analytical data are studied by statistical analysis. In Method I, the heats of hydration are correlated with the calculated compound content, i.e., CJS, C2S, C3A, and C4AF as the independent variables, and in Method II, they are correlated with the corrected C3S and C2S and glass content as calculated by the series of equations derived by Dahl, as the independent variables. Comparisons with observed values show that predicted values calculated bv Method II compare favorably with those by Method l, so that estimatibns can be more accurately and reliably made.
