Abstract

The CP method is extended in order to give more precise prediction of the expansive cement effects on thermal cracking prevention for early age concrete. The feature of the extended CP method is based on the conservation law of chemical energies, which is quite different concept than the initial strain calcula- tion that has been used extensively in the past. Then, the formulation for thermal stress analysis based on the law is proposed. Finally, the effect of expansive cement on reducing thermal stress is numerically clarified us- ing the extended CP method.
