Pervious concrete can also reduce the impact of development on trees.

Slump and air content tests are not applicable to pervious concrete because of the unique composition.

The section is notable for the first use in British construction of the slip form paver using pervious concrete.

Pervious concrete is made using large aggregates with little to no fine aggregates.

Pervious concrete consists of cement, coarse aggregate and water with little to no fine aggregates.

Concerns over the resistance to the freeze-thaw cycle have limited the use of pervious concrete in cold weather environments.

Pervious concrete is widely available, can bear frequent traffic, and is universally accessible.

Pervious concrete was first used in the 1800s in Europe as pavement surfacing and load bearing walls.

Pervious concrete can significantly reduce noise, by allowing air to be squeezed between vehicle tires and the roadway to escape.

The addition of a small amount of fine aggregate to the mixture increases the durability of the pervious concrete.

Pervious concrete is traditionally used in parking areas, areas with light traffic, residential streets, pedestrian walkways, and greenhouses.

Pervious concrete is a mix of specially graded coarse aggregate, cement, water and little-to-no fine aggregates.

Pervious concrete also naturally filters storm water and can reduce pollutant loads entering into streams, ponds and rivers.

Pervious concrete, used in permeable paving, contains a network of holes or voids, to allow air or water to move through the concrete.

Pervious concrete is installed by being poured into forms, then screeded off, to level (not smooth) the surface, then packed or tamped into place.

An alternative solution today is to use permeable paving surfaces, such as brick, pervious concrete, Rock (geology), special paving blocks, or tire-tread woven mats.

In order to save water, the park collects rain water, has a composting toilet, Clivus multrum that uses no potable water, waterless urinals, and pervious concrete.

Alternatively, preconditioned absorptive lightweight aggregate as well as internal curing admixture (ICA) have been used to effectively cure pervious concrete without waste generation.

The most popular is to incorporate land-based solutions to reduce stormwater runoff through the use of retention ponds, bioswales, infiltration trenches, sustainable pavements (such as pervious concrete), and others noted above.

- The TCA is also known to be a supporter of environmentally friendly methods of using concrete in paving, among these the use of pervious concrete for permeable paving.

The proper utilization of pervious concrete is a recognized Best Management Practice by the U.S. Environmental Protection Agency (EPA) for providing first flush pollution control and stormwater management.

Whether pervious concrete, porous asphalt, paving stones or concrete or plastic-based pavers, all these pervious materials allow stormwater to percolate and infiltrate the surface areas, traditionally impervious to the soil below.

Pervious concrete (also called porous concrete, permeable 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.

The city is still working on how, and how often, to clean porous concrete.

This concrete is also known as "no-fines" or porous concrete.

This not only provides a better key for the render but prevents the porous concrete from sucking the water from it.

'Porous concrete', like porous asphalt, can bear frequent traffic, and is universally accessible.

The state Department of Environmental Protection, which oversees state parks, plans to pave the dirt trail with a porous concrete and replace its wooden staircase with stone steps.

Salt water migrating into the porous concrete caused the rusting of the rebar steel reinforcements resulting in expansion of the steel and causing cracking of concrete.

At least a liter of blood marked the point of impact, so fresh that a portion had still not soaked into the porous concrete but glistened in small, red, shallow puddles.

Most nuclear reactors use thick concrete shields to create a bioshield with a thin water cooled layer of lead on the inside to protect the porous concrete from the coolant inside.

Scarpetta gets out a presumptive blood kit and swabs areas of the wall where she saw the luminol react, working the cotton tip into the porous concrete where blood might lurk, even after washing.

Monolithic structures consist of a single continuous porous medium such as porous concrete or porous pavement (asphalt) while modular structures include porous pavers individual paving blocks that are constructed so that there is a gap in between each paver.

The astringent scent of pine disinfectant masked but didn't entirely conceal a sour odor, which was probably milk that had dripped from a punctured carton on delivery and then soaked into the porous concrete, but which smelled to Dusty like curdled blood or old puke, evidence of cruelty or crime.

Pervious concrete (also called porous concrete, permeable 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.

Care must be taken in doing so, however, as water from the damp ground, water vapour (entering from crawl space vents), and moisture seeping through porous concrete can create a perfect environment for mould/mildew to form on any surface in the crawl space, especially cardboard boxes, wood floors and surfaces, drywall and some types of insulation.
