How to make permeable concrete
Web2 mrt. 2024 · Properties of Permeable Concrete. A permeable concrete mix is generally prepared by restricting the water-to-cement ratio to 0.28 to 0.4 with a void content of 15 to 25 percent. The average flow rate of water through permeable concrete is 0.34 cm/s. WebWhen people talk about green pavement, they are usually referring to permeable pavement. Unlike traditional asphalt or concrete, permeable pavement is porous; it allows water to run through it rather than pool on top or run off of it. Water percolates, as in a coffee pot, when it seeps through the pavement to a cleansing layer of gravel.
