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