The National Ready Mixed Concrete Association has released 2PE003 — Guide to Improving Specifications for Ready Mixed Concrete which uses Master Specification CSI format Section 03300 for cast-in-place concrete to propose specification clauses and provides accompanying commentary as guidance. The discussion helps initiate specification revisions for sustainable and optimized concrete mixtures for improved performance.

The publication evolved through comments provided to actual specifications used for commercial projects. The commentary essentially emphasizes the fundamental concepts of specifications for ready mixed concrete addressed in industry standards published by ACI or ASTM International. Provisions of ACI 318-08, Building Code for Structural Concrete, as it relates to requirements, concrete ingredient materials and mixtures, production and delivery, are incorporated in this document. The guidelines have been reviewed and approved by the NRMCA Research Engineering and Standards Committee.

The NRMCA member price is $25; non-members, $40.

NRMCA, based in Silver Spring, MD, represents the producers of ready mixed concrete and the companies that provide materials, equipment and support to the industry. It conducts education, training, promotion, research, engineering, safety, environmental, technological, lobbying and regulatory programs.
