Nano-hybrid concrete chemical admixture for chloride invasion resistance consisting of layered double hydroxide/polyurethane copolymer |
摘要 |
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. |
