Materials Structure Temperature Fissure Analysis of Reinforced Concrete Structure

摘要

The temperature fissure of high building concrete structure and mass concrete was attentioned increasingly. The essence of which must be understood before studying the temperature fissure of concrete material. So the heat transfer mechanism in cement based materials was discussed in different ways. The source of heat, which induces temperature fissure of cement-based material is analyzed in this paper. The heat transfer mechanism of different states of matter affected by the thermal conductivity is also involved. Based on that the cement-based material is a three-phase composite, it can be concluded that the heat transfer must be studied considering conduction, convection and radiation comprehensively, and being combined with general theory of statistics.
