A new type admixture was developed for super workable concrete in water-cement ratio of 40-55%. The cost of concrete using this admixture will be less expensive because of using less powder and admixture content. This admixture is the polycarboxylate type water-soluble copolymer composed of the cement dispersing component and the water reducing component which effect segregation resistance. Since these components have closely chemical structures, the solution of this admixture is very stable. Super workable concrete using this admixture has as same fluidity and segregation resistance as usual super workable concrete, though having less viscosity. The properties of this hardened concrete, -strength, shrinkage, durability and fire resistance-, and influence of mix proportion were made clear by investigation in comparison with conventional concrete that has same water content, same water-cement ratio and slump of 18cm. And the appropriate mix design method of this concrete was proposed.
