| Abstract: | Based on a new model for heat of hydration of cement,which takes the influence of temperature and the concentration of reactant into account,the temperature field was analyzed.The finite element program simulates the transient temperature field in massive concrete constructed layer by layer by controlling the contribution of each element to global stiffness matrix and load vector.The law of temperature field was illuminated through a simple example. |
