The National Ready Mixed Concrete Association's "Concrete In Practice" (CIP) Series is a popular 1-page discussion sheet on a variety of technical topics written in a "What, Why and How?" format. They are intended to provide information in a non-technical format.

The CIP's are written by members of the NRMCA Research, Engineering and Standards Committee. Several new CIPs have been added: CIP37-Self Consolidating Concrete, CIP38-Pervious Concrete, CIP39-Concrete Maturity, CIP40-Aggregate Popouts, and CIP41-Acceptance Testing of Concrete.

CIP of the Month:

Pervious concrete, also known as porous concrete, is a no-fines mix produced with little or no sand or fine aggregates, allowing water to drain down into a crushed stone reservoir. It can be colored for a more asthetically pleasing appearance. Pervious concrete is an integral part of a stormwater management system, and important conditions like the amount of water runoff and subsurface soil conditions are important factors for successful implementation.
