Pervious Concrete | Porous Concrete | Permeable Concrete

06-Sep-2021

Based on the definition given by American Concrete Institute (ACI,2010) “pervious concrete” typically describes as a near zero-slump, open-graded material consisting of Portland cement, coarse aggregate, little or no fine aggregate, admixtures, and water. With the little or no fine aggregate, it will produce pores ranging in size from 0.08 to 0.32 in. (2 to 8 mm) that allowed the water partials to pass through easily. The increasing of pores size increases the void contain by 15 to 35%, with typical produce the compressive strengths of 2.8 to 28 MPa.

Applications Of Porous Concrete:

  • Residential roads, streets and driveways.
  • Low-volume pavements.
  • Sideways and avenues.
  • Parking area.
  • Tennis Court.
  • Sub-base for traditional concrete pavements.
  • In Well linings.
  • Swimming pool decks.

Advantage of Pervious Concrete:
1. ENVIRONMENTAL BENEFITS:

  • It reduces storm water runoff replenishes water tables and aquifers.
  • It eliminates detention ponds that are costly for storm water management practices.
  • It permits extra environment-friendly land growth.
  • It prevents warm and polluted water from getting into streams.

2. SAFETY BENEFITS:
  • Minimizes flash flooding and standing water.
  • Skidding is lowered.
  • Light reflectivity is greater than asphalt surfaces; therefore reduce the heat island effect.
  • Glare from the wet pavement is virtually eliminated.

Disadvantages of Pervious Concrete:
  • Runoff from adjacent areas onto pervious concrete needs to be prevented.
  • The parking areas are generally limited to auto parking and occasional trucks.
  • If reinforcement is required, epoxy-coated bars should be used.
  • Concrete has variable permeability;
  • Over-vibration significantly reduces permeability.
