Permeability concrete
WebFeb 7, 2024 · Permeable concrete is considered an environmentally friendly construction material, and has been quickly gaining recognition as a green building component. WebPermeability is the ability of a given sample of concrete to permit liquids or gases to pass through it. It is the measurement of the amount of water, air, and other such substances that can enter the concrete through its pores. Concrete contains some pores in its structure. These pores are the route for substances to enter the concrete element.
