ICRI Releases New Technical Guidelines

Comment | More

Specifiers, applicators, producers and other concrete repair professionals can find updated guidance on critical topics in several new resources published by The International Concrete Repair Institute.

ICRI has released two new technical guidelines and updated a third for the concrete repair industry.

The new Technical Guidelines are:

• No. 320.5-2012, Pictorial Atlas of Concrete Repair Material Mixing Equipment; and

• No. 320.6-2012, Guide for the Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures.

The revised Technical Guideline is 320.3R-2012, Guide for Inorganic Repair Material Data Sheet Protocol.

Pictorial Atlas of Concrete Repair Material Mixing Equipment

The goal of this eight-page publication is to provide a single-source common guide that can be used in the trade when describing or specifying mixing equipment.

Pictorial Atlas of Concrete Repair Material Mixing Equipment

Specifying equipment for mixing concrete repair materials is extremely difficult, because the industry uses multiple names for the same equipment and the same names for different equipment.

The problem has been that different types of mixing paddles and mixers can produce different consistencies and properties in concrete repair products. ICRI sees this guide as the solution to ensuring that the appropriate equipment is properly described or specified.

The atlas does not advocate one type of paddle or piece of equipment over another or discuss mixing efficiency or other properties.

The Pictorial Atlas of Concrete Repair Material Mixing Equipment is available only for purchase as a downloadable PDF file from the ICRI web site. The cost is $30 for ICRI members; $49, for nonmembers.

Guide for the Evaluation and Repair of Unbonded Post-Tensioned Concrete Structures

The product of a collaboration between ICRI and the Post-Tensioning Institute (PTI), this guide provides an introduction to the techniques and procedures used to evaluate and repair existing concrete structures post-tensioned with unbonded single-strand tendons.

Guide for the Evaluation and Repair Of Unbonded Post-Tensioned Concrete Structures

The 54-page guide demonstrates how the strength and serviceability of a structure that has experienced deterioration can be evaluated and restored to its original—or greater—strength and serviceability.

Post-tensioning design, evaluation, and repair require specialized knowledge. There is no substitute for experience and knowledge in working with post-tensioned structures. An experienced contractor and licensed design professional team are essential when working with post-tensioned structures.

The publication can be ordered ($46 for members; $74 for nonmembers) by calling 248-848-3809 or visiting ICRI Guidelines are available in printed form or as a downloadable PDF.

Guide for Inorganic Repair Material Data Sheet Protocol

Updated for 2012, this 13-page publication is designed to provide a consistent, logical, and systematic methodology for testing and reporting information for cement-based repair materials.

Guide for Inorganic Repair Material Data Sheet Protocol

The data sheet protocol allows specifiers to choose verifiable properties optimized for their selected requirements of a particular repair situation. Applicators can obtain useful information about yield, working time, surface preparation, application temperature range, curing, and compatibility, as well as verify the material performance. Material producers can optimize products based on market needs and technology improvements, rather than concentrating on closely passing acceptance levels of an existing specification in a commodity-based market.

This free ICRI Guideline is only available as a downloadable PDF file from the ICRI web site.

ICRI, a nonprofit association with more than 2,000 members worldwide, is a leading resource for education and information to improve the quality of repair, restoration and protection of concrete and other structures.

Might be a transposition error on the costs otherwise it is better to be a non-member.

Bill, thanks for the pickup! The article has been corrected.
