Engineered Cementitious Composite - an overview ...

7.6.1 Engineered cementitious composites (ECC) One way to minimize crack widths in concrete is through the use of engineered cementitious composites (ECC) as developed by Li (2003, 2005) and by Li and Stang (2004). ECC is a fibre reinforced cementitious composite, containing typically about 2% fibres by volume.

Engineered cementitious composite - Wikipedia

Engineered Cementitious Composite (ECC), also called Strain Hardening Cement-based Composites (SHCC) or more popularly as bendable concrete, is an easily molded mortar-based composite reinforced with specially selected short random fibers, usually polymer fibers. Unlike regular concrete, ECC has a strain capacity in the range of 3–7%, compared to 0.01% for ordinary portland cement (OPC) paste, mortar or concrete. ECC therefore acts more like a ductile metal material rather than a brittle glassmateri
