摘要：
This paper deals with the characteristics of a temperature-time function to account for the combined effects of temperature and time on the strength development of concrete. Starting with a differential equation to describe the rate of strength gain under isothermal curing conditions, it is shown that the product of age and the rate constant is the sought-after function. By using the Arrhenius equation to represent the variation of rate constant with temperature, a function, called 'effective age', is proposed which better describes the effects of temperature and time on strength development for isothermal curing.
