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

Article Preview

Abstract:

For concrete double mixing with slag powder and fly ash, in order to more accurately measure the temperature and crack, the calculation model of transient temperature field is established by finite element method, as taking the temperature controlling of massive concrete mixing with slag powder and fly ash of pile cap in Dongsha Bridge for example. The effect of cooling water temperatures and pouring temperature on temperature field of pile cap are analyzed. The results show that the cooling water temperature has less effect on central maximum temperature in early days, but more effect on cooling rate in late stage. The pouring temperature has more effect on maximum temperature. The temperature peak will rise with pouring temperature increasing, but the time of temperature peak arising is invariant.
