Prediction of temperature and aging effects on the properties of concrete

Abstract

For the sustainable concrete structures, it is necessary to exactly predict the material properties of concrete with age and each place of structures. This paper investigates prediction models estimating the temperature and aging effects on the hydration properties of concrete, such as the compressive strength, the splitting tensile strength, the elastic modulus, and the autogenous shrinkage. A prediction model is suggested on the basis of an equation that is formulated to predict the compressive strength. Based on the assumption that the apparent activation energy is a characteristic property of concrete, a prediction model for the compressive strength is applied to hydration-related properties. The hydration properties predicted by the model are compared with experimental results, and it is concluded that the prediction model properly estimates the splitting tensile strength, elastic modulus, and autogenous shrinkage as well as the compressive strength of concrete.
