Shape factors for concrete shrinkage and drying creep in model B 4 refined by nonlinear diffusion analysis

Abstract

The source of shrinkage and drying creep is the drying process. From the diffusion analysis of drying one can estimate the shrinkage strain. Same as drying, the shrinkage times scale as the square of the effective specimen thickness (or size), D, commonly characterized by the volume-surface ratio. But there is also an additional effect of cross section… (More)
