Optimization of time and temperature of dam construction for thermal analysis of RCC dam
In RCC dams, usually large amounts of concrete are poured in a short time that the heat generated by the cement hydration has led to an increase in temperature in the dam body. In this research, Abacus software, which is a finite element software, has been used for thermal analysis of the dam during construction and concreting. This is how thermal changes are applied. For the structure of 50 c...
