Abstract: Glass fiber-reinforced concrete premix technology is becoming increasingly popular worldwide for manufacture of precast concrete products used in industrial, architectural, civil engineering, and construction applications. Glass fiber-reinforced concrete premix products provide a useful balance of properties such as strength, toughness, durability, moisture resistance, dimensional stability, fire resistance, and aesthetics. This report summarizes the current knowledge of materials, manufacturing methods, engineering properties, and applications of glass fiber-reinforced concrete premix.
