ECC Mortar
Engineered Cementitious Composite (abbreviated as ECC) is a new type of fiber-reinforced cementitious composite developed based on micro-mechanism design theory. This product is compounded with well-graded cement, quartz sand, admixtures and high-performance polymer fibers (PVA fibers) with special surface treatment. Compared with traditional mortar or concrete, ECC mortar exhibits remarkable strain-hardening performance and multiple micro-cracking behavior under tensile and flexural loads. Its ultimate tensile strain can exceed 3%, far higher than ordinary concrete, and it boasts ductility similar to metal, hence it is known as "bendable cement".
