The material ingredients which make up ECC are similar to FRCs that is it contains cement, sand, water, and admixtures. However, coarse aggregates are not used in ECCs (hence it is a mortar rather than concrete). Additionally, ECC uses low amounts, typically 2% by volume, of short, discontinuous fibers.
