Developing Advanced Construction Materials to Improve, Repair, and Maintain Reclamation's Concrete Structures

Project ID: 362
Principal Investigator: Kurt Von Fay
Research Topic: Repair and Maintenance
Funded Fiscal Years: 2004, 2005 and 2006
Keywords: None

Project Abstract

There are many modern concrete construction materials that are introduced onto the market every year. Many of these products will have beneficial application to Reclamation facilities. However, many Reclamation facilities are unique and were built with a variety of materials and technologies that are not well represented in other sectors of the large civil works community. Because we must protect, maintain, and improve these critical facilities, the suitability of new technologies for use on Reclamation structures should be evaluated before we specify their use.Because thin repairs to concrete have poor track record, a main component of this program is to evaluate those
materials. From previous S&T work, a good start has been made on developing new test procedures to measure important material properties. We have also identified desired values for those properties. This program will extend that work by evaluating new test procedures, and testing repair materials.

Development of a Test Method to Evaluate Cracking Tendency of Repair Materials, Phase I Report (final, PDF, 2.2MB)
By Benoit Bissonnette, Tim Dolen, Alex Vaysburd and Kurt Von Fay
Report completed on March 30, 2005

This project focuses on the performance of cementitious repair materials in concrete surface repairs with the main goal of minimizing cracking. The specific objectives of the project are to:

• Develop a laboratory/field reliable test method to evaluate the long-term performance of repair materials and, particularly, their sensitivity to cracking

• Assess the reliability of some of the existing test methods for evaluating the cracking tendency of repair materials

• Contribute to the dev

Development of Test Methods to Evaluate Cracking Tendency of Repair Materials—Field Study Phase II (final, PDF, 1.7MB)
By Benoit Bissonnette, Alex Vaysburd and Kurt Von Fay
Report completed on May 28, 2009

The objectives of the Phase II study of the CREEP project is to correlate results from selected test methods from Phase I and the ASTM ring test to experimental repairs. The scope of the work of the Phase II study is to establish the correlation, if any, between:

• Ring test (ASTM C1581) material evaluations and its in-situ performance

• Baenziger block test and experimental repairs

• Free shrinkage (ASTM C157) and experimental repairs
