    Abstract: PROBLEM TO BE SOLVED: To provide a ground improvement method capable of suppressing the underwater diffusion of soil by hardening the inland and the marine ground at a proper rate.
    SOLUTION: In this ground improvement method, (1) the soluble salt of the (co) polymer of an ethylenic unsaturated carboxylic acid, (2) soluble bicarbonate, as necessary, (3) an organic acid (salt) and a polyphosphoric acid (salt), and (4) an additive including a defoaming agent are mixed in a cement-containing hardening material at 0.1 to 25/100 mass ratio. The water slurry of the thus obtained cement compound is filled in the ground and hardened so that the volume ratio thereof becomes 0.1 to 1.5.

    Abstract: PROBLEM TO BE SOLVED: To provide a dispersant which can give better workability and filling property than usual through a year to, in particular, ultrahigh strength concrete by keeping fluidity in a short time after kneading.
    SOLUTION: The dispersant for a hydraulic composition uses two kinds of copolymers containing a polyalkylene glycol (meth)acrylate-based monomer (a) in which the mean additional molar number of an alkylene oxide is in a specific range and an unsaturated monomer (b) whose specific rate is specified as structural units so that the product of the mean additional molar number of each alkylene oxide and the weight percentage of (b) to the sum of (a) and (b) expressed in terms of acid type has a specific relation.

    Abstract: PROBLEM TO BE SOLVED: To degas the air of a working face and obtain a smooth surface scarcely having bubbling trace by laying a self-leveling floor material after aqueous solution of surfactant having specific surface tension is applied on the working face. SOLUTION: An aqueous solution is obtained from a surfactant whose surface tension is 65-15 mN/m, after spray is applied on a concrete face after hardening, a self-leveling material is poured, and hardening is performed without smoothing with trowel. The air of the working face is degassed by applying surfactant aqueous solution on the working face of a concrete slab or the like, and the smooth surface scarcely having bubbling trace can be obtained. In other words, the permeation effect of the self-leveling material are expressed by lowering interface tension between the working face and the self-leveling material, degassing action is improved, and adhesion with a finishing member is excellent.

    Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition useful as an admixture for a hydraulic composition capable of suppressing the material separation of water, gravel or the like and improving the operating efficiency by including a specific copolymer and a ligninsulfonic salt or its derivative in a specific proportion. SOLUTION: This composition is obtained by including (A) a copolymer prepared by polymerizing a monomer mixture containing a monomer represented by formula I (R1 and R2 are each H or methyl; m1 is 0-2; AO is a 2-3C oxyalkylene; n is 2-300; X is H or a 1-3C alkyl) [e.g. an esterified substance of methoxypolyethylene glycol with (meth)acrylic acid] and one or more kinds of monomers represented by formula II or III [R3 to R5 are each H, methyl or the like; R6 is H or methyl; M1 and Y are each H or a cation] [e.g. (meth) acrylic acid or (meth)allylsulfonic acid] and (B) a ligninsulfonic salt or its derivative in (10/90) to (90/10) weight ratio of the components A/B.

    Abstract: PROBLEM TO BE SOLVED: To produce centrifugally molded concrete while remarkably controlling the amount of sludge discharged and the solid content of the sludge. SOLUTION: A polyoxyalkylene (2-3C)-containing polymer is added to fresh concrete containing an aromatic dispersant during or after charging the concrete into a molding flash. The aromatic dispersant is preferably a water-soluble salt of a naphthalenesulfonic acid-formaldehyde condensation product. The polyoxyalklene (2-3C)-containing polymer is preferably a water-soluble copolymer obtained by polymerizing a monomer mixture containing one or more vinyl monomers (a) having 2-300 mol 2-3C oxyalkylene groups added on the average and one or more vinyl monomers (b) having a carboxy, sulfo or amide group.
