STUDY ON EFFECT OF PORE WATER BEHAVIOR AND VISCO-ELASTIC BEHAVIOR ON CREEP MECHANICS OF CONCRETE

Abstract

The analytical model for creep mechanism of concrete as a porous permeable material was established. In the analytical mode, the diffusion phenomenon and seepage phenomenon for pore water were introduced in detail and then the model was expanded so as to be able to be taken the visco-elastic behavior of pore water and cement paste into account. The effect of water migration on the creep phenomenon was estimated due to the analytical and experimental study. Moreover, the degree of water migration behavior effect and visco-elastic behavior effect of cement paste on the creep phenomenon was estimated due to the analytical and experimental study and then the creep mechanism was probed.
