Temperature Effects on Strength Evaluation of Cement-Based Materials with Ultrasonic Wave Reflection Technique

Curing temperature has an effect on the hydration kinetics, and resulting strength gain, of Portland cement. This article reports on a study in which the temperature effects on the relationship between the compressive strength of paste, mortar, or concrete and the reflection loss obtained with ultrasonic shear-wave reflection (UWR) measurements were observed. In the study, three different constant curing temperatures (15, 25, and 35 deg C) were used for a given paste or mortar. The established correlations between the two studied parameters were then verified by applying alternating curing temperatures to the mortar. As a third component, the temperature dependence of the relationship between the two studied parameters was further verified by observing concrete cured under various conditions. The results determined that, for a given material, the relationship between the reflection loss and the compressive strength is independent of curing temperature. The authors conclude that the temperature independence of the established linear relationship between reflection loss and compressive strength enhances the potential of the UWR method for strength prediction of concrete in the field.
