Abstract :
    Today, with the proliferation of massive concrete structures in the country and the use of cement with high doses, there is the possibility of thermal cracking.The heat generated increases the temperature of the concrete structure and thermal gradient and heat transfer between the concrete and the concrete will occur.Thermal stress caused by the bound volume changes can cause thermal cracks in massive concrete structures. Therefore, it is necessary to check the profiles of temperature of this type of structures. Given that the supplementary cementations materials in concrete forming temperature is reduced ,In this essay, the influence of silica fume concrete and cement replacement on the increase or decrease heat generation and finally effect the decrease or increase the cracks in massive concrete structures is investigated. This is a compilation of a series of activities to help ABAQUS software is experimental and numerical.
