Development of fiber-reinforced reactive Mgo cement composites

Fiber-reinforced strain-hardening cementitious composites (SHC) exhibit ultra-high tensile strain capacity and are used in both modern construction and repairing a deteriorating building. One major disadvantage of SHC is its high Portland cement (PC) content, which is associated with high energy req...
