Abstract:
A few test data are offered to show the exceedingly slow rate of penetration of drying shrinkage into a mass of concrete. From these data, support is obtained for the view that the loss of moisture from concrete can be computed by applying the laws of diffusion, just as the loss of heat from a cooling body is computed. For a typical case, drying is shown to penetrate only l about 8 in. into a mass of concrete after a ful year of continuous drying at 50 percent relative humidity. Substantially no moisture is shown to .be lost beyond the depth of 8 in, at the end of the year.
