Concrete, repair materials: Water diffusion (NT BUILD 369)

Abstract

SCOPE

The water diffusion coefficient of concrete repair materials and protecting coatings is determined by a laboratory test in which transfer of water occurs under the influence of differences in relative humidity. The diffusion coefficient is calculated on the basis of the loss of weight from a diffusion cell.

FIELDS OF APPLICATION

The method can be used to evaluate concrete repair materials, both mortars and coatings.
