混凝土立柱早期性能演变规律研究
摘要
The mathematical model of adiabatic temperature rise of concrete structure under the action of hydration heat is established, the generation and change law of hydration heat is obtained through finite element analysis. Through the field temperature measurement, the center temperature of column section appears the peak value of 72 when pouring 63h, and then the temperature decreases slowly. The result is basically consistent with the simulation analysis. Finally, the relationship between hydration degree and early performance of concrete is obtained by concrete performance test. The research results provide a reference for the curing time and technology of concrete structure.
