反応が不十分による強度不足や乾燥収縮によるひび割れ
等が発生することが知られている。<Prior art> - If concrete, etc. is poured into an Ill using a formwork and then removed from the mold before the concrete is completely cured, water will escape from the concrete quickly and hydration will occur. It is known that insufficient strength due to insufficient reaction and cracks due to drying shrinkage occur.
そこで上記のような欠点を解決するために、例えばコン

クリート表面に養生膜を形成させる方法等が提案されて
いる。Therefore, in order to solve the above-mentioned drawbacks, for example, a method in which the formwork is not removed until the concrete has completely cured, a wet curing method in which water is applied after the formwork is removed, and shielding materials such as sheets have been developed. A method of shielding and curing the concrete surface, and a method of forming a curing film on the concrete surface have been proposed.
しかし、これらの方法では、不十分に養生効果と養生材
被膜の性能が得られないのが実情である。However, the reality is that these methods do not provide sufficient curing effects and performance of the curing material coating.

徴とする養生材によって達成される。The above object of the present invention is achieved by a curing material which is made of an acidic alkaline earth metal soluble resin and is characterized by forming a curing film on the surface of concrete after casting and demolding in concrete construction.
本発明による酸性のカチオン性アルカリ硬化型水溶性樹

のカチオン性水溶性樹脂であることが望ましい。The water-soluble resins of acetate, formate, and lactate of the acidic cationic alkali-curing acrylic ester copolymer used in the present invention are mainly composed of acrylic resin and are stable in contact with cement. , and acidic, although not particularly limited, preferably resin solid content is 20 to 50% by weight, viscosity (25°C) 100 to 600, CPSS pH 3 to 5.5
The cationic water-soluble resin is preferably a cationic water-soluble resin.
この際樹脂固型分が２０％重量未満では、コンクリート
等に対する所望の接着性が得られず、５０重量％を超え

好ましくない。In this case, if the resin solid content is less than 20% by weight, the desired adhesion to concrete etc. cannot be obtained, and if it exceeds 50% by weight, the viscosity becomes high and problems arise in workability, which is not preferable.

することが出来る成分である。Moreover, when the pH is outside the above range, the adhesion to concrete etc. is weak. Generally, cationic polymers obtain adhesive properties only by electrical adsorption, but the cationic alkali-curable acrylic ester copolymers used in the present invention - acetate, formate, and lactate water-soluble resins In addition to electrical contact, the alkali curing reactive groups on the surface of the acrylic resin particles cause a crosslinking reaction with the alkali component of the cement, resulting in strong chemical bonding, as well as weather resistance, UV resistance, and ozone resistance. It is a component that can impart properties such as alkali resistance and water resistance.
養生材の塗布量は特に、０．１〜０．３ｋｇ／ｎｆであ
