Modeling Hydration of Cementitious Systems

Abstract

heat loss is measured and minimized by the use of insulation. The concrete adiabatic temperature rise is then back-calculated with the increased heat of hydration rate from the higher temperatures in adiabatic conditions taken into account. Semiadiabatic calorimetry is much easier to perform than adiabatic calorimetry, and it can even be performed in the fi eld. The infl uence of temperature on the hydration rate can be accounted for by the use of a maturity function. The equivalent age maturity function is commonly used with strength or degree of hydration calculations, as shown in Eq. (
