Transport of water in concrete under real environment was analyzed by the hybrid model of capillary suction and nonsaturated diffusion. While concrete surface was subjected to liquid water, the water transport phenomenon was modeled by capillary suction process into concrete pores. The water loss or gain, while concrete surface was exposed to the air, was described by nonsaturated diffusion model considering capillary condensation and diffusion of vapor and liquid water in concrete pores. The analytical results were verified with the experimental results under real environment. |
