What is Prediction of Compressive Strength of Fly Ash Concrete by New Apparent Activation Energy Function about?

A new prediction model using apparent activation energy is proposed to estimate the variation of compressive strength of fly ash concrete with aging. After analyzing the experimental result with the model, fly ash replacement content and water -binder ratio influence on apparent activation energy was investigated. According to the analysis, the model provides a good estimation of compressive strength development of fly ash concrete with aging. As the fly ash replacement content increases, limiting relative compressive strength and initial apparent activation energy increase. Concrete with water -binder ratio smaller than 0.40 gives nearly constant limiting relative compressive strength and initial apparent activation energy when analyzed with various water -binder ratios. However, concrete with water -binder ratio larger than 0.40 increases limiting relative compressive strength and initial apparent activation energy.
