Title (EN) CEMENT MIXING AGENT
(FR) AGENT DE MÉLANGE DE CIMENT
(JA) セメント混和剤
Abstract:
(EN) In the conventional methods, the performance of a syneresis inhibitor under high-temperature conditions is insufficient yet. Thus, the present invention provides a cement mixing agent having an excellent syneresis-inhibiting effect at a higher temperature. The cement mixing agent according to the present invention comprises a crosslinked product of a modified poly(vinyl alcohol)-type resin, and has a property such that the dissolution rate of 1 g of the crosslinked product of the modified poly(vinyl alcohol)-type resin in 1 litter of water at 70ºC is 50% or less.
(FR) Dans les procédés classiques, l'efficacité d'un inhibiteur de synérèse dans des conditions de température élevée est encore insuffisante. Aussi, la présente invention concerne un agent de mélange de ciment ayant un excellent effet inhibiteur de synérèse à une température plus élevée. L'agent de mélange de ciment selon la présente invention comprend un produit réticulé d'une résine de type alcool polyvinylique modifié, et possède une propriété de sorte que la vitesse de dissolution de 1 g de produit réticulé de résine de type alcool polyvinylique modifié dans 1 litre d'eau à 70 °C est inférieure ou égale à 50 %.
(JA) 従来の方法では高温下での離水抑制剤の性能は未だ満足いくものではなく、本発明は高温での離水抑制効果に優れるセメント混和剤を提供する。本発明のセメント混和剤は、変性ポリビニルアルコール系樹脂の架橋物を含有し、70℃の水1リットルに対する前記変性ポリビニルアルコール系樹脂の架橋物1gの溶解率が50%以下である。
