permeability of concrete Topic

Sep 01, 2021 · 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 ...
