    Both the low mortar content and high porosity also reduce strength compared to conventional concrete mixtures, but sufficient strength for many applications is readily achieved.

    While pervious concrete can be used for a surprising number of applications, its primary use is in pavement.

    ASTM C192 provides procedures for evaluation of different mixtures in laboratory conditions.

    It is usually used in the initial stage of the project, or for research purposes.

    This site focuses on the pavement applications of the material, which also has been referred to as porous concrete, permeable concrete, no-fines concrete, gap-graded concrete, and enhanced-porosity concrete.

    By capturing stormwater and allowing it to seep into the ground, porous concrete is instrumental in recharging groundwater, reducing stormwater runoff, and meeting U. Environmental Protection Agency (EPA) stormwater regulations. In fact, the use of pervious concrete is among the Best Management Practices (BMPs) recommended by the EPA—and by other agencies and geotechnical engineers across the country—for the management of stormwater runoff on a regional and local basis.There are three main functions of curing: 1) Maintaining mixing water in concrete during the early hardening process Ponding and immersion Ponding is typically used to cure flat surfaces on smaller jobs.Care should be taken to maintain curing water temperature at not more than 20 degrees Fahrenheit cooler than the concrete to prevent cracking due to thermal stresses.Roanoke Cement, a Titan America company, provided support to museum to ensure strong representation for pervious.Museums such as this provide ongoing education to state residents and especially help children get an early understanding of how applications such as pervious concrete are of benefit to their lives and world.
