Abstract
Recent developments in admixture technology can dramatically modify and control both the rheological and hardened properties of concrete. Using the right combination of specific admixtures and appropriate mixture proportions are the first steps towards producing concrete with the desired performance attributes. For example, a system of innovative admixtures can now produce a novel concrete mix that facilitates the rapid repair of concrete pavements that permits opening to traffic within just 4 hours after concrete placement. This paper provides a description of the concrete system and its components, includes test data, and contains a review of successful projects, and demonstrations for local and national transportation agencies.
