Abstract:
The author argues that there is a common misunderstanding that viscosity is the primary or sole property defining the flow or penetrability of a liquid. While viscosity is an important parameter, equally important is the liquid’s affinity for surfaces with which it comes into contact. While this property is well known in the field of surface science, it’s often overlooked by engineers and contractors in the concrete industry. Existing test standards used for evaluating the wetting behaviors of liquids in contact with solids are proposed as potential guidelines for the development of standards for use in the concrete industry.
