用的でなくなる恐れがある。The ratio of (meth)acrylate to cement in the O-blended composition of the present invention has a great effect on adhesive strength and curing time, so the type of cement, (meth)acrylate, oxidizing agent, etc. used is Although the ratio must be determined with careful consideration, generally good results can be obtained if the ratio is 228 to 7:3 (weight ratio), so it is a preferable range, and more preferably 6:7 to 3. The ratio is 7:3. Outside this range i.e. (
When the amount of meth)acrylate increases relative to cement,
The cured product becomes too flexible and shrinks significantly, and when used in small amounts, the adhesive strength becomes weak (there is a risk that it may become impractical as an adhesive for civil engineering and construction).
なお、上記組成比の範囲内で（メタ）アクリル酸塩を増

な優れた効果を奏するものと思われる。"Function" Although it is not clear by what mechanism the adhesive composition of the present invention can rapidly cure and strongly adhere various materials, especially those whose adhesive surfaces are wet,
The gel produced by the polymerization of (meth)acrylate, especially magnesium acrylate, interacts with calcium contained in cement, and the acceleration of the above reaction due to the heat of polymerization of (meth)acrylate is involved. It is believed that these actions produce the above-mentioned excellent effects that are the object of the present invention.
