Vacuum Concrete: Meaning, Applications, Advantages and Disadvantages

https://www.constructioncost.co/vacuum-concrete.html

Vacuum concrete, also known as pervious concrete or porous concrete, is a type of concrete that has a highly porous structure. It is created by leaving out or reducing the number of fine aggregates such as sand in the mix, which allows for voids or pores to form in the hardened material. The voids or pores in the concrete create a network of interconnected channels, allowing water to pass through the concrete instead of pooling on the surface. This makes vacuum concrete ideal for areas that experience heavy rainfall or flooding, as it helps to prevent water buildup and reduce runoff.
