セメントを用いた通常のセメントコンクリートやモルタ

び割れし易い、防水性が不足している、接着力が小さい
等の欠点を有している。Conventional cement concrete and mortar using cement have drawbacks such as low tensile strength and bending strength, large drying shrinkage and easy cracking, insufficient waterproofness, and low adhesive strength.
この欠点を改善する目的で従来、セメントに合成ゴムラ

台まれる乳化剤のために硬化後のセメントの圧縮強度が
低下するだけでなく、硬化前のセメントスラリーのチク
ソ性が増大して作業性が著しく悪化するなどの問題があ
る。Conventionally, synthetic rubber latex or synthetic resin emulsion has been mixed into cement in order to improve this drawback, but the compressive strength of cement after hardening increases due to the large amount of emulsifier contained in these latex or emulsion. There are problems such as not only a decrease in the hardness but also an increase in the thixotropy of the cement slurry before hardening, resulting in a marked deterioration of workability.
この問題を解決する手段の1つとして、乳化剤を含まな

キシ樹脂は乳化剤を併用しなければセメントと混合せず

混入することによる前述の問題点は依然として解決され
ない。One way to solve this problem is to use a resin that does not contain an emulsifier as a cement binder, and research using epoxy resin, which is a hardening type resin, is actively being conducted, but water-soluble epoxy resin When blended with cement, although the bending strength of the cured cement product improves, the compressive strength inevitably decreases. In addition, hydrophobic epoxy resins do not mix with cement unless an emulsifier is used, and if an emulsifier is used, the above-mentioned problem due to the resin being mixed into the cement remains unsolved.

脂の硬化剤として作用するためであると推定される。The inventors of the present invention have conducted extensive studies in view of the above points, and as a result,
We have discovered that a certain additive is extremely effective in modifying cement containing epoxy resin, and have completed the present invention. That is, according to the present invention, when a salt of a homopolymer or a copolymer of an unsaturated dicarboxylic acid is added to a cement containing an epoxy resin, the properties of the polymer cement are fully utilized, and the It can improve the compressive strength as well as the tensile strength and bending strength of the cement, and it can also increase the fluidity of the cement slurry before hardening, improving workability during mortar work or concrete work. The reason why such an excellent cement-modifying effect can be obtained by adding a salt of a homopolymer of the unsaturated dicarboxylic acid to an epoxy resin-containing cement is because of the homopolymer of the unsaturated dicarboxylic acid. It is presumed that this is because the salt of the coalescence or copolymer forms an adduct with the epoxy resin, which is uniformly dispersed and dissolved in the cement, and further acts as a hardening agent for the epoxy resin when the cement hardens.

Both solutions B were mixed. Thirty-five seconds after mixing, the viscosity started to thicken and gelation progressed, but the rise was gradual (Comparative Example-1). On the other hand, ethylene-maleic anhydride copolymer (Monsanto Co., Ltd. EMA 1103) was added to liquid A.
Add and dissolve 7 g of sodium salt of ) and add the following to liquid B: hydrophilic epoxy resin (glyceryl polyglycidyl ether type, Nagashio Sangyo Denacol EX314) 0.02
