Everything you need to know about Pervious Concrete
A key component of structural strength and essential building material is concrete. By virtue of its name, we automatically assume that concrete must be impenetrable, leak- and damp-proof, and strong enough to support the load. Concrete must be impermeable to water since, in RCC constructions, it will cause steel to corrode.
As a result, the name "pervious concrete" is misleading and unclear. So why should previous concrete be utilized? We are talking about previous concrete here. Yes, at first glance, concrete and that transparent material seem inappropriate and nonsensical.
The concrete industry does, however, employ one significant environmentally friendly substance as an eco-friendly industrial practice for tackling pollution control, stormwater management, and sustainable design.
Cement, coarse aggregates, water, and, if necessary, admixtures and other cementitious ingredients, make up the unique form of concrete known as pervious concrete. No fine aggregates, which are typically employed in the concrete matrix, are present in this form of concrete.
Because there are more vacant spaces in the material, water may move more easily through it. As a result, pervious concrete is also known as porous concrete or permeable concrete.
Open cell structures made of porous concrete enable rainfall to permeate the pavement and seep into the underlying soils. In other words, the environment and pavement surface on which it rests are both protected by this concrete.
The same components that go into making regular concrete also go into porous concrete. A network of linked voids that make up 15–30% of its volume allows water to travel through the concrete.
Applications of Pervious Concrete
1. Low-traffic pavement
2. driveways, lanes, and roads in residential areas
3. paths and sidewalks
4. places for parking
4. low-water bridges
5. courts for tennis
6. underpinning for traditional concrete pavements
7. stability of slope
8. linings of wells
9. hydraulic systems (where permeability is accepted)
10. Decking of swimming pools
11. sidewalk tree grates and pavement edge drains
12. Seawalls and groins
