多い。However, alumina cement has the disadvantage of a decrease in strength due to crystal transition after hardening, and calcium sulfoaluminate (c, 8 ZCS> cement) has problems with strength development and stability at low temperatures (crack formation due to pig intestine). For example, when emergency construction is carried out in winter, the expected strength may not be obtained by the next day, and expansion cracks often occur due to the expansion nature of C1^ and C3 as the temperature rises. .

がある。In order to solve this problem, the use of alkali metal salts such as sodium carbonate as shown in Japanese Patent Application Laid-open No. 52-82928 was considered. Furthermore, since it stiffens too quickly, it has poor workability, and since it contains alkali metals, it may cause an alkali aggregate reaction, resulting in swelling and disintegration.

な速硬性セメントを提供しようとするものである。SUMMARY OF THE INVENTION Therefore, the present invention aims to provide a fast-setting cement that has excellent strength development and stability at low temperatures, is free from alkali aggregate reaction, and is inexpensive.
〔課題を解決するだめの手段］
本発明は課題を解決するため次のような構成としたもの
である。[Means for Solving the Problems] In order to solve the problems, the present invention has the following configuration.

Clinker whose main component is CS (also referred to as Align) 20-60%, Boltland cement clinker 20-70ffi1%, Type anhydrous plaster 0.5-30%, plain It consists of 0.1 to 3.0% by weight of lithium carbonate with a value of 5000 cd/g or more and 0.05 to 2% by weight of oxycarboxylic acid such as citric acid, and a part of the above type anhydrous gypsum is mixed during the grinding of the clinker. The remainder is added as a coarse powder with a plain value of 3000 cffl/g or less, and the chemical component of cement, S(
It is a fast-hardening cement with a h/AbOs molar ratio of 1.4 to 1.0.

ンガイド又はモノサルフエイトを形成することになる。The first feature of the present invention is that it uses not only a clinker whose main component is calcium sulfoaluminate, that is, a special cement clinker, but also a Bortland cement clinker, that is, an ordinary cement clinker. be. This composition allows cost reduction, and the hardening mechanism is that calcium sulfoaluminate reacts with calcium hydroxide produced from Portland cement during hydration to form ettrin guide or monosulfate. I will do it.
本発明の第２の特長は、溶解速度の遅い■型無水せっこ

せるためである。即ち、全てのせっこうを微粉にすると
安定性が悪化し、量を減らすと長期強度が低くなる。The second feature of the present invention is that type anhydrous gypsum with a slow dissolution rate is used, and a part of it is mixed and ground with cement clinker to form a fine powder, and a thin ettrin guide is placed around the cement particles during hydration. Forms a film to prevent instant setting (
The reason why the remaining part was made into a coarse powder state was to make it contribute to the development of strength after setting, regardless of the reaction immediately after driving. That is, if all the gypsum is pulverized, stability deteriorates, and if the amount is reduced, long-term strength decreases.
なお、微粉末状態（プレーン値７０００〜１２０００ｃ
＋ｆ／ｇ）とするものは６０％、粗粉状態（プレーン値
３０００ｃ１１１／ｇ以下）のものは４０％程度とした
場合、使い勝手がよい。In addition, fine powder state (plain value 7000~12000c)
+f/g) and 40% for coarse powder (plain value 3000c111/g or less), it is convenient to use.
本発明の第３の特長は、炭酸アルカリとしてプレーン値
５０００ｃ＋Ｉｌ／ｇ以上の炭酸リチウムを使用した点
である。The third feature of the present invention is that lithium carbonate with a plain value of 5000c+Il/g or more is used as the alkali carbonate.
このように炭酸リチウムを微粉砕して添加すると、低温

が向上する）保存性に優れた速硬性セメントを提供でき
る。When pulverized lithium carbonate is added in this way, it promotes the reaction of calcium sulfoaluminate even at low temperatures, but it is stable because it does not cause an alkaline aggregate reaction like when other alkali metal carbonates are used. This has the effect of producing concrete with high strength. In addition, it is possible to provide a fast-setting cement with excellent storage stability (lower hygroscopicity and improved weathering resistance) than when other alkali carbonates are added.
また、他のアルカリ金属炭酸塩ではクエン酸等凝結遅延
剤を加えてもなおこわばりが速く、作業性が悪いが、炭
酸リチウムでは作業性が確保される。In addition, other alkali metal carbonates tend to stiffen rapidly even when a setting retarder such as citric acid is added, resulting in poor workability, but lithium carbonate ensures workability.
本発明の第４の特長は、クエン酸等オキシカルボン酸を
併用したことである。即ちオキシカルボン酸を配合して
おくことによりカルシウムサルホアルミネートの低温安
定性が確保される効果がある。The fourth feature of the present invention is that oxycarboxylic acids such as citric acid are used together. That is, by incorporating oxycarboxylic acid, the low-temperature stability of calcium sulfoaluminate is ensured.
