摘要：

In Europe, massive concrete elements often are made with blast-furnace slag cements. To better deal with the problem of early-age thermal cracking in these cases, a new hydration model for blast-furnace slag cements is developed, which is based on isothermal and adiabatic hydration tests. In the hydration model, the heat production rate is calculated as a function of the degree of hydration and the temperature. The accuracy of temperature simulations using this new hydration model is evaluated by tests on hardening massive concrete cylinders made with blast-furnace slag cement.
