  • Nano-hybrid Concrete Chemical Admixture for Chloride Invasion Resistance Consisting of Layered Double Hydroxide/Polyurethane Copolymer
    Publication number: 20120046393
    Abstract: The present invention relates to a chloride penetration resistant nano-hybrid concrete chemical admixture comprising layered double hydroxide and polyurethane copolymer. More specifically, nano-hybrid concrete chemical admixture obtained by combining the two compounds at a nano-scale, the layered double hydroxide which exhibits resistance to chloride penetration, and polyurethane copolymer which entails an excellent water reducing ability, durability and workability. In addition, the inorganic/organic hybrid material described herein exhibits high water reducing ability, improved resistance to chloride penetration, and thus can be used as chloride penetration resistant concrete chemical admixture for marine concretes.
