Sažetak
Temperature of the mixture has a very large influence on the rate of hydration in cement- based materials. Therefore, temperature is often measured during experiments if there is the need to compare properties of material which undergoes different temperature history. Broadly accepted approach for considering influence of temperature on the rate of hydration is maturity principle. Different maturity functions are used which require at least one parameter which characterizes temperature sensitivity of the mixture. In this paper a numerical modelling approach in used for evaluation of hydration rate which is based on the heat flow within the sample being tested. Temperature measured within the sample serves as an input parameter for modelling and the temperature field throughout the specimen is reconstructed. Calculation procedure also evaluates amount of heat generated at each time step. An example calculation is presented which deals with the heat generation in cement paste sample during ultrasonic pulse velocity test.
