ASTM International Committee to consider standards for pervious concrete

ASTM Committee C09 on Concrete and Concrete Aggregates
will hold a planning meeting for proposed new standards
activity on pervious concrete on December 4 at the C09 meeting
in Atlanta, Ga. The committee is especially seeking researchers
who have been experimenting with different types of
tests for pervious concrete, as well as specifying engineers, concrete
technologists and contractors.
“Many concrete industry experts consider pervious concrete
to be the next big thing in the marketplace,” says Karthik
Obla, senior director of research and materials engineering,
National Ready Mixed Concrete Association. Although pervious
concrete has been available since the 1970s, primarily in
Florida, Obla attributes newfound interest in the material to the
Environmental Protection Agency’s recent recognition of pervious
concrete as a best-management practice for storm water
management.
In addition, an increasing focus on sustainability has generated
interest in pervious concrete. For example, the Leadership
in Energy and Environmental Design Green Building Rating
System, a voluntary, consensus-based national standard for developing
high-performance, sustainable buildings, now recognizes
pervious concrete and offers points for using storm water
management in a building project.
Obla says that proposed new standards to be considered
will be used to qualify pervious concrete mixtures and to facilitate
product acceptance testing of pervious concrete in projects.
Possible standards to be developed include permeability and
density tests, as well as standards for making pervious concrete
cylinders for strength.
