    Abstract: Compuesto hidráulico, que comprende un material hidráulico y un derivado de polisacárido preparado por sustitución de la totalidad o una parte de los átomos de hidrógeno del hidroxilo de un polisacárido o derivado de polisacárido por (A) un sustituyente alquil gliceril éter, en el que el grupo alquilo tiene de 12 a 36 átomos de carbono como estructura parcial y (B) un sustituyente hidrofílico iónico que tiene, como mínimo, un miembro seleccionado entre el grupo que consiste en grupos sulfónico, carboxílico, fosfórico, y sulfato y sales de los mismos como estructura parcial, en el que el grado de sustitución por el sustituyente (A) es de 0, 001 a 1 por residuo de monosacárido constituyente determinado por espectrometría NMR; y el del sustituyente (B) es de 0, 01 a 0, 5 por residuo de monosacárido constituyente determinado por titulación coloidal.

    Abstract: A CONCRETE ADMIXTURE IS PROVIDED, WHICH IS EFFECTIVE IN IMPARTING FLUIDITY TO A HYDRAULIC COMPOSITION SUCH AS CEMENT PASTE, MORTAR OR CONCRETE, PARTICULARLY IN MAINTAINING THE FLUIDITY OF THE COMPOSITION AND WHICH HARDLY RETARDS THE HARDENING PROPERTY OF THE COMPOSITION. SAID CONCRETE ADMIXTURE COMPRISES A COPOLYMER COMPRISING, AS STRUCTURAL UNITS, UNITS DERIVED FROM AN ETHYLENICALLY UNSATURATED MONOMER (A) HAVING 25 TO 300 MOLES OF C2-C3 OXYALKYLENE GROUPS AND UNITS DERIVED FROM A MONOMER (B) OF AN ALKYL, ALKENYL OR HYDROXYALKYL ESTER OF AN ETHYLENICALLY UNSATURATED MONO- OR DI- CARBOXYLIC ACID.

    Abstract: THE INVENTION PROVIDES A PROCESS CAPABLE OF EASILY PRODUCING A WATER-SOLUBLE SALT OF A NAPHTHALENESULFONATE FORMALDEHYDE CONDENSATE WITH A REDUCED AMOUNT OF UNREACTED FORMALDEHYDE. WHEN NAPHTHALENESULFONIC ACID IS SUBJECTED TO CONDENSATION REACTION WITH FORMALDEHYDE TO PRODUCE A NAPHTHALENESULFONATE FORMALDEHYDE CONDENSATE, A SULFITE IS ADDED TO THE REACTION SYSTEM AFTER THE CONCLUSION OF THE CONDENSATION REACTION. WHEN A CEMENT DISPERSANT COMPOSITION IS OBTAINED, THE PROCESS INCLUDES A STEP OF NEUTRALIZING THE CONDENSATE.

    Abstract: PCT No. PCT/JP97/02095 Sec. 371 Date Feb. 20, 1998 Sec. 102(e) Date Feb. 20, 1998 PCT Filed Jun. 18, 1997 PCT Pub. No. WO97/48656 PCT Pub. Date Dec. 24, 1997A concrete admixture is provided, which is effective in imparting fluidity to a hydraulic composition such as cement paste, mortar or concrete, particularly in maintaining the fluidity of the composition and which hardly retards the hardening property of the composition. The concrete admixture comprises a copolymer comprising, as structural units, units derived from an ethylenically unsaturated monomer (a) having 25 to 300 moles of C2-C3 oxyalkylene groups per mole of copolymer and units derived from a monomer (b) of an alkyl, alkenyl or hydroxyalkyl ester of an ethylenically unsaturated mono- or di-carboxylic acid.

    Abstract: PCT No. PCT/JP94/02097 Sec. 371 Date Jun. 13, 1996 Sec. 102(e) Date Jun. 13, 1996 PCT Filed Dec. 14, 1994 PCT Pub. No. WO95/16643 PCT Pub. Date Jun. 22, 1995An admixture for concrete comprising, as an essential component, a copolymer prepared by copolymerizing (a) a polyalkylene glycol monoester monomer having 110 to 300 mols of an oxyalkylene group(s) each having 2 to 3 carbon atoms, with (b) at least one monomer selected from among acrylic monomers, unsaturated dicarboxylic monomers and allylsulfonic monomers. When this admixture is used in preparing concrete, the resulting concrete composition undergoes little change in the slump for a lengthened time, so that the quality of the concrete composition can be easily controlled.
