Pervious Concrete Additive

We are prominent manufacturer and exporter of Pervious Concrete Additive in Jinan, Shandong, China. Pervious concrete (also called porous concrete, permeable concrete, no fines concrete and porous pavement) is a special type of concrete with a high porosity used for concrete flatwork applications that allows water from precipitation and other sources to pass directly through, thereby reducing the runoff from a site and allowing groundwater recharge. Pervious concrete is made using large aggregates with little to no fine aggregates. The concrete paste then coats the aggregates and allows water to pass through the concrete slab. Pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and greenhouses. It is an important application for sustainable construction and is one of many low impact development techniques used by builders to protect water quality.

Dosage:

10 to 15 kilograms per cubic metre of pervious concrete to reach 20Mpa compressive strength.

Using Instruction
Firstly add the cement, aggregate, then add half of the water dosage, stirring for 30s;
Secondly add the pervious concrete cementing admixture (pigment),stirring for 60s;
Thirdly add the remaining water, stirring for 120s.
