すると、同時に大幅に速硬性を阻害する傾向にあった。Conventionally, this kind of cement compound is used as a super-fast hardening cement such as jet cement (trade name of Onoda Cement Co.) by adding a retarding agent such as citric acid, or as a quick-setting agent for Portland cement or mixed cement. It is manufactured by adding a retarder. However, when an attempt was made to increase the fluidity of the cement mixture by using the retarder, there was a tendency that the rapid hardening property was significantly impaired at the same time.

If it is less than 0.1% by weight, the fluidizing effect is substantially absent, and if it is added in excess of 10% by weight, the effect of improving the fluidity reaches a ceiling.

上好ましくない。By adding a retarder such as citric acid, sulfonic acid, phosphonic acid, saccharides and their derivatives together with the fluidizing agent used in the present invention, the fluidity is synergistically improved. can do. Therefore, it is desirable to add these retarders according to the desired fluidity and quick setting. The retarder is added in an amount of 0.01 to 3% by weight based on the above-mentioned various cements. If it is less than 0.01% by weight, there is substantially no synergistic effect with the fluidizing agent, and if it exceeds 3% by weight, rapid hardening is significantly impaired, which is not preferable in practice.

動化できる。According to the present invention, by adding a polycarboxylic acid and / or a polycarboxylic acid salt to a paste, mortar, or concrete having a quick setting property, the polycarboxylic acid and / or the polycarboxylic acid salt charges the cement particles. Since the cement particles are prevented from agglomerating by being given each other and repelling each other, they can be fluidized without impairing the quick-hardening property of the quick-hardening cement mixture.
