A simple method for characterizing and predicting temperature behavior of ternary cementitious systems

The present study is aimed at developing a simple method for characterizing and predicting temperature behavior of ternary cementitious system. Mortar mixes produced with different combinations of various cement and supplementary cementitious materials (SCMs) were investigated. The temperature rises of these mortars were measured using a thermocouple. The slopes of the major temperature peak, maximum temperature, time to the maximum temperature, and area under the curve were used to characterize the heat generation behavior of the mortars. The initial and final set time of the mortars were measured according to ASTM C403. The results indicate that the mortar temperature curves can be well characterized. The parameters and the mortar set time can be well predicted.
