Finite Element Simulation of Hydration Heat Using Fuzzy Logic Model of Hydration

Abstract:

This paper deals with heat of hydration in a concrete structure at the early age. The influence of temperature on development of hydration heat in the concrete structure is implemented through a fuzzy-logic model of the degree of hydration. The transient heat transfer problem was solved as a three-dimensional finite element simulation. The whole process of calculation is implemented in MATLAB Environment. The result of this work provides temperature distribution in the structure for each time step, the maximum temperature in the structure, and the time when it occurs.
