Study of the Influence of Capillary Water Surface Tension on Drying Shrinkage and Self-Shrinkage Deformation of Concrete
By analyzing and simplifying the force status about the concave water surface and wall of concrete capillary pores,the model for force calculation of capillary walls is established.When the concave water surface is going down,capillary walls will contract. Concrete volume shrinkage strain at different surface tension is approximately calculated out by using finite element software ANSYS,from which the relationship between the surface tension of capillary water and drying shrinkage,early self-shrinkage of concrete is obtained.
