    Abstract: PURPOSE:To improve the flowability of a super high strength concrete and the reduction of viscosity and to hold slump for a certain time by using a polymer and its metallic salt obtained from a monomer such as a specific glycol monoester, acrylic acid, polyethylene glycol, oxycarboxylic acid, etc., as essential components. CONSTITUTION:This admixture contains three components of (1) the copolymer and its metallic salt obtained by polymerizing the polyalkylene glycol monoester monomer, the acrylic acid monomer and/or an unsaturated carboxylic acid monomer, (2) polyethylene glycol having 5000-100000av. molecular weight and (3) one or more kinds among compounds of oxycarboxylic acid and its salts, sugar and sugar-alcohol as the essential components. The admixture is improved in flowability, viscosity and slump holding property, etc., of concrete, particularly in the super high strength concrete having

    Abstract: PURPOSE:To provide a cement admixture for bettering dispersibility, suppressing loss of slump and improving strength and durability in a cement paste, etc., as a cement composition. CONSTITUTION:A cement admixture comprises (A) a copolymer obtained by polymerizing a polyalkylane glycol monoester-based monomer having an unsaturated bond with an acrylic acid-based monomer and/or unsaturated dicarboxylic acid-based monomer and/or a metal salt of the copolymer and (B) polyethylene glycol. Consequently, effects of pressure feed operation by a pump is extremely raised by using the cement admixture as a pump-pressure feed auxiliary for concrete, the cement admixture is effective for maintaining fluidity and preventing separation of material and is expected to improve strength and durability.

    Abstract: PURPOSE:To make it possible to keep the target air flow rate for a long period by using an aqueous emulsion of a long-chain fatty acid ester as an air- entraining agent for concrete. CONSTITUTION:An admixture (air-entraining agent) for concrete obtained by using an aqueous emulsion of a fatty acid ester, e.g., methyl laurate, consisting of an 8-18C fatty acid and a 1-10C alcohol and having 0.05-20mum, preferably 0.05-10mum average particle diameter. The above-mentioned admixture for concrete can be used with other admixtures, such as commercially available water- reducing agents, slump loss preventive agents or hardening accelerators. The amount of the admixture to be added to the cement is normally 0.01-0.3% based on the cement.
