HEAT OF HYDRATION AND DEVELOPMENT OF MOISTURE CONTENT

HYDRATATIONSWAERME UND FEUCHTIGKEITSENTWICKLUNG

From the chemically bound water which can be determined simply and accurately, it is possible to find a direct connection between all portland and blast furnace cements with the heat of hydration determined by the method for the heat of solution, and it is possible further to calculate the degree of hydration and from this the density of the colloid and the capillary volume. The relationships between the hardening time, the tensile strength in bending and strength of compression as well as the dynamic e-modulus with the colloidal density enable calculations to be made for final strength as well as the required hardening time. It is possible to calculate the highest possible degree of hydration for each water-cement ratio from the limiting value for water that can be chemically bound, and also the water-cement ratio which just permits complete hydration. The results of these calculations for various cements and water-cement ratios were checked and confirmed. /TRRL/
