INNOVATIONS FORUM : Engineered Cementitious Composites for Structural Applications

In the last several years, the University of Michigan has been investigating a composite material known as Engineered Cementitious Composites (ECC). In many respects, this material has characteristics similar to medium- to high-strength concrete. However, the tensile strain capacity generally exceeds 1% with the most ductile composite in the 6-8% range. This article briefly reviews these emerging materials and also reports on some ongoing developmental application studies. The relatively small amount of fibers (less than or equal to 2%) utilized ensures economic feasibility in practical applications, whether in precast elements or on-site constructions. Results of the studies provide confidence in the widening use of ECC in a broad range of new and retrofitted concrete structures.
