Abstract: A hydraulic composition comprises a water soluble polymer, a superplasticizer, and a hydraulic powder. Because it becomes possible to secure a high flowability, a segregation resistance of aggregate, and a strength, a method for using concrete and a method for applying concrete are markedly improved. Particularly in the production of concrete products, large repercussion effects to noise prevention and production rationalization are expected.

Abstract: Polysaccharide derivatives in which some or all of the hydroxyl groups have been substituted by hydrophobic substituent(s) (A) having as the partial structure a C8-43 hydrocarbon group, and ionic hydrophilic substituent(s) (B) having as the partial structure at least one group selected from the group consisting of sulfonate, carboxyl, phosphate and sulfate groups and salts thereof, which have an average degree of substitution per constituting monosaccharide residue by the substituent (A), determined by Zeisel's method or the diazomethane method, of at least 0.0001 but less than 0.001 and an average degree of substitution per constituting monosaccharide residue by the substituent (B), determined by the colloidal titration method, of from 0.01 to 2.0. These derivatives are useful as chemical admixtures for hydraulic materials and give hydraulic compositions excellent in dispersibility and stability.

Abstract: A hydraulic composition containing a water-soluble polymer comprising a polyalkylene oxide derivative having a hydrophobicity of 50 KOHmg/g or less in terms of the hydroxyl value of the terminal hydroxyl groups, a surfactant having a weight-average molecular weight of 5,000 or less, a superplasticizer, and a hydraulic powder. As the composition ensures high fluidity, segregation resistance and strength, it brings about remarkable improvements in the methods of using and placing concrete, and it has particular effects on the noise reduction and process rationalization in the production of concrete products.
