- Abstract
- The relationships between the chemical characteristics of portland cements and the heat of hydration at 7 and 28 days and at 1 year were studied by computing multivariable regression equations with the aid of a digital computer and determining which of the independent variables appeared to have a significant relationship to the heat of hydration values. The computed equations verified to a reasonable degree effects usually attributed to the major potential compounds. Other commonly determined variables, such as fineness and loss on ignition, were associated with the heat of hydration at all ages; K2O and SO3 with the 7 day; and Na2O with the 1-year heat of hydration. Of the other minor constitutents Cu and P appeared to be associated with the heat of hydration at all ages. In addition, Cr and Zr were associated with heat of hydration at 7 days; Co, Zr, and SrO at 28 days; and V and Ba at 1 year.
