【 摘 要 】

Basing on the theories of compound mixtures, considering the development of the microscopic pore structure of concrete at early age, and the dynamic balance of adsorbed water, free water, and water vapor within the pores, the thermo-hygro-mechanical coupling model was established with temperature, humidity, hydration degree and capillary pressure as main variables.
