Temperature Sensitivity Analysis of Temperature Control Parameters for Massive Concrete Mixing with Slag Powder and Fly Ash

Abstract:

In order to make the temperature controlling measure of massive concrete mixing with slag powder and fly ash effectively. Taking Guangzhou East Bridge sand cap-based temperature control project for example，the pile caps transient temperature field calculation model is established by finite element method. The different water cooling time and hydration rate are analyzed. The results show that the cooling time extending has less effect on central maximum temperature of double-doped concrete in early stage, but the times arriving corresponding stable temperature is earlier. The hydration rate has more effect on maximum temperature.
