Use of Isothermal Conduction Calorimetric Method for Measuring the Heat of Hydration of Cement

CODEN: JAIOAD

Abstract

In the present study, an extensive test program is conducted to measure and compare the heat of hydration obtained from both calorimeter and ASTM C186-05 test methods. A statistical analysis is performed to evaluate the variations of the test data. The results indicate that the isothermal conduction calorimeter method is a more reliable, less time-consuming, and less labor-intensive method than the ASTM C186-05 test method. The heat of hydration at 3 days showed the least variation in all calorimeter tests. These suggest that ASTM shall consider adopting the isothermal conduction calorimeter method for measuring the heat of hydration of cement. The 3-day heat of hydration value can be used for specifying the limit of heat release for type II cements.
