CRSI Standards Documents

The Concrete Reinforcing Steel Institute (CRSI) is an approved Standards Development Organization (SDO). The scope of CRSI’s standards activities will be to develop and maintain consensus standards for design, detailing, fabrication, placement, and construction of assemblies consisting of steel reinforcement and associated products used in concrete and masonry construction.

Supports for Reinforcement Used in Concrete

$39.95/non-member
$9.95/members

This specification covers the design, use, and material requirements of reinforcement supports used in concrete to support various types of reinforcement, including but not limited to plain and deformed reinforcing bars, prestressing steel, post-tensioning tendons, steel wire, and plain and deformed steel welded wire reinforcement. Reinforcement supports shall be made of material that is structurally sound and inert in concrete, such as metal, cementitious (precast), or a composite (plastic) material. Any type of reinforcement support may be selected, provided the support maintains the required concrete cover and that it meets specific project required.



The proposed standards appear in ANSI's Standards Action newsletter. Standards Action is ANSI's key public review vehicle. Published weekly, it provides members and the public with timely, accurate information and enables effective participation in the standards development process -- both in this country and internationally.
