Detailed Description
Grey Color Water Permeable No fines Concrete for Walkingways
Introduction
No fines concrete (also called porous concrete, permeable concrete, pervious 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.
Usage
In no fines concrete, carefully controlled amounts of water and cementitious materials are used to create a paste that forms a thick coating around aggregate particles. A no fines concrete mixture contains little or no sand, creating a substantial void content. Using sufficient paste to coat and bind the aggregate particles together creates a system of highly permeable, interconnected voids that drains quickly. 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.
Advantages
-Increase the compressive strength, tensile resistance and crack strength;
-Increase the cement paste quantity, increase the compactness;
-Reduce the cement dosage, reduce the hydration heat and the shrinkage and the crack;
-Increase 3~7days early strength;
-Increase the freeze-thaw resistance property to above 200 circles;
-Bonding strength is above 220psi;
-Resistant hydraulic pressure of above 220psi, water proof performance;
-Inhibition of alkaline reaction, avoid the crystallization and sand out.
-Resistant of erosion of chloride ion
