RESULTS FOR PERMEABILITY OF CONCRETE

Definition: the ability of a given concrete to permit liquids or gases to pass through.- ACI Concrete Terminology


Permeability is a measure of the amount of water, air, and other substances that can enter the concrete matrix. Concrete contains pores that can allow these substances to enter or depart. Permeability of concrete can be a primary reason for concrete deterioration due to reinforcing steel corrosion and other deterioration mechanisms. On a macro scale, permeability also refers to “porous” slabs used to drain pavements, sidewalks, and parking areas of water, eliminating the need for drainage slope, structures, and piping. This technology—sometimes called “no-fines concrete”—is gaining popularity again with the desire to reduce surface run-off from pavements, sidewalks, and parking areas.
