Development and Testing of Chemically-Based Self-Consolidating Concrete

Abstract:

Self-consolidating concrete (SCC) has the potential to significantly reduce costs associated with concrete construction. SCC is a highly flowable, nonsegregating concrete that has a variety of advantages over conventional concrete (CC). However, SCC is not without its problems, which can include increased creep and shrinkage, as well as decreased bond and shear strength. The goal of this research project was to evaluate the creep, shrinkage, and shear behavior of a chemically-based SCC mix. One of the benefits of a chemically-based approach is the potential to eliminate the negative side effects of many SCC mixes. The investigation included development of the mix design, construction and testing of creep and shrinkage specimens, and construction and testing of full-scale beam specimens to evaluate the shear behavior. The results indicate that a chemically-based SCC performs as well or better than conventional portland-cement concrete.
