    A pervious concrete street in 2005. Pervious concrete (also called porous concrete, permeable concrete, no fines 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.

  4. Permeable paving - Wikipedia

    en.wikipedia.org/wiki/Permeable_paving

    Permeable pavement surfaces may be composed of; pervious concrete, porous asphalt, paving stones, or interlocking pavers. [1] Unlike traditional impervious paving materials such as concrete and asphalt, permeable paving systems allow stormwater to percolate and infiltrate through the pavement and into the aggregate layers and/or soil below. In ...

    en.wikipedia.org/wiki/Types_of_concrete

    Pervious concrete, used in permeable paving, contains a network of holes or voids, to allow air or water to move through the concrete This allows water to drain naturally through it, and can both remove the normal surface-water drainage infrastructure, and allow replenishment of groundwater when conventional concrete does not.

    It is usually not recommended to replace more than 20% of the lime content with cement when rendering the facade, and it is a matter of contention whether adding any concrete is ever appropriate in order to maintain the benefits of lime over concrete. Lime plaster is permeable and allows for the diffusion and evaporation of moisture.

    It also flows much better than ordinary concrete, having the consistency of a milkshake. The first known use of CLSM was in 1964. [ 2 ] CLSM is typically a ready mix concrete rather than soil cement which is a low strength cement made using local soil, and is similar to a slurry .

    The rebuilt upper reservoir of the Taum Sauk plant, nearing completion in this photo, is the largest RCC dam in North America. [1]Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for portland cement.
