Engineered cementitious composites: design, performance and applications
This paper gives a brief overview of Engineered Cementitious Composites (ECC) as an emerging construction material. ECC is a fiber reinforced cement based composite material systematically engineered to achieve high ductility under tensile and shear loading. Emphasis is placed on the accumulated knowledge on durability, safety, and sustainability of reinforced ECC (R/ECC) structures, recognizing that the concrete of the future must meet these characteristics. A number of current applications of this material technology are highlighted. In light of these recent full-scale field applications of ECC, the limited studies on long-term performance of ECC are also summarized. Materials like ECC, with ultra ductility and tight crack width control, however, show characteristics that may meet the demands of next generation construction. A large amount of research remains to be conducted to fill the knowledge gaps of this relatively new construction material. However, ECC has already emerged from the laboratory into full-scale field applications. These applications will provide useful feedback into the re-design of ECC to meet specialized requirements for different applications. The micromechanics based materials engineering of ECC will aid substantially in further tailoring of this material, as is already happening in green ECC design for sustainability and in lightweight ECC for applications where dead-load needs to be minimized. The recent applications also generate extremely important structural design knowledge.
