SIMULATION OF HYDRATION AND CRACKING PROPAGATION WITH TEMPERATURE EFFECT BAWSED ON FUZZY LOGIC THEORY

Abstract

This paper deals with the influence of temperature and temperature history on the development of hydration heat in concrete structures and on evaluation of temperature distribution in earlyage concrete. The main objective of this work is estimation of temperature influence on hydration progress in concrete during hydration reaction, then the evaluation of hydration rate, cumulative hydration heat and evolution of actual material strength. Further, the risk of cracking in concrete structure due to shrinkage and linear thermal expansion is estimated and based on results of crack risk analysis, the depth and geometry of the crack is obtained.
