Abstract
A nano-modified dry-mixed alkali-activated cementitious, or one-part geopolymer cement (OPgC), material with high early strength is provided for rapid repair of cement-based infrastructure components. The OPgC may include an aluminosilicate rich material, an alkali material and a nano-modifier, and optionally include other functional admixtures and fibers. The OPgC can be freshly mixed with water to obtain a repairing material. The OPgC may mix with water and fine or coarse aggregate to form mortar or concrete. The OPgC can be an alternative binding matrix for the development of an environmentally friendly and cost effective rapid repair material.
