Compressive strength, permeability, and porosity of pervious concrete with variation of w/c and compaction methods

Pervious concrete is known as permeable concrete, no-fine concrete, and porous concrete. This innovation is to create concrete which can be passed by water with the result that can be used for rigid pavement. Variation of water-cement ratio and compaction methods are used for this research. Compaction with rodding stick, proctor Hammer, and vibrator are conducted to each 0,28, 0,30, and 0,32 of water-cement ratio mix. Compressive strength, permeability, and porosity test is taken on 10 x 20 cm cylinder specimen. For the measurement of permeability testing setup is developed based on falling head method. Result of this research shows that compressive strength increases as the increase of water-cement ratio, while the permeability is decreasing. This paper reports the impact of water-cement ratio and compaction methods variation on compressive strength, permeability, and porosity of pervious concrete.
