Abstract

Wind accelerates drying shrinkage of concrete in early age, but this mechanism of acceleration is unknown yet. Then, this article tried to make clear the mechanism of water evaporation under air turbulence condition using model of boundary surface of concrete. From this article, it is made clear that not only wind but also air turbulence accelerates water evaporation from concrete surface by considering RH on concrete surface and the thickness of boundary surface of concrete. And, it is known that when water to cement ratio is large, namely, concrete is porus, air turbulence the effect of air turbulence to drying is great.
