The tensile strength and ductility of normal concrete are dissatisfactory and these lead to some durability problems for reinforced concrete structure. On the other hand, China’s production and consumption of concrete is the largest in the world, and with the rapid economic development the number also continue to increase. A new class of more sustainable cement-based materials is urgently needed in China. This paper reports on the development of engineering cementitious composites (ECC), and a unique green high-performance fiber-reinforced cementitious composite (GHPFRCC) with high volumes of fly ash and PVA fiber is proposed. The detailed procedure of GHPFRCC is presented. The calculated equations of the load-bearing capacity of the reinforced concrete column retrofitted by GHPFRCC are proposed.
