Permeable Concrete Pavements - Enviromental Concrete

Pervious concrete is delivered to the jobsite by conventional ready-mix trucks and placed within standard forms. Because pervious concrete is thicker in consistency than regular concrete, a vibrating mechanical screed is used to level it off. Vibration is followed by compaction with a heavy steel roller to attain greater strength.

19.4.2 Pervious geopolymer concrete. Pervious concrete, porous concrete, or water permeable concrete is a concrete with a high void content to allow water or air to permeate. In general, pervious concrete has pores with sizes in the range of 2–8 mm, the void content is 18%–35% and the compressive strength is 2.8–28.0 MPa ( ACI 522, 2010 ).
