Explained: Cement vs. concrete — their differences, and
Apr 03, 2020What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration. "Hydration occurs when cement and water react," says Ulm. "During hydration, the clinker dissolves into the calcium and recombines with water and silica to form calcium silica hydrates."

:: Pervious Pavement :: Pervious Concrete for Green, Sustainable
Typically, between 15% and 25% voids are achieved in the hardened concrete, and flow rates for water through pervious concrete are typically around 480 in./hr (0.34 cm/s, which is 5 gal/ft/ min or 200 L/m/min), although they can be much higher.
