It is widely used because it is easy to manufacture and has good fluidity, is easy to transport, does not require cost, and has good workability. And, when concrete is constructed, it is poured into the formwork and poured.For example, when the fluidity is large, or when the formwork is not securely installed, the concrete flows out from the gap of the formwork. In the case where concrete is constructed in a place where water is present, such as an underground void, there is a problem that the material is separated and a hardened concrete of stable quality cannot be obtained. In addition, when concrete is applied to a space such as a wall, a ceiling surface, a ground, and a back surface of a tunnel, there is a problem that the concrete is dripped or peeled off, making it difficult to perform the operation.

好ましい。The alkali metal aluminate (hereinafter referred to as aluminate) used in the present invention includes sodium aluminate and potassium aluminate. Usually, the molar ratio of R 2 O / Al 2 O 3 of the aluminate is preferably 0.8 to 2.6, and more preferably 1.5 to 2.0. Outside this range, the quick-setting properties may decrease. The amount of aluminate used is
The amount is preferably 0.5 to 10 parts, more preferably 1 to 5 parts in terms of solid content based on 100 parts of cement. If the amount is less than 0.5 part, strength developability may not be obtained, and if it exceeds 10 parts, the quick-setting effect is not improved, and the subsequent long-term strength expression may be delayed. These aluminates are preferably used in the form of a suspension or an aqueous solution mixed with water from the viewpoints of handleability, meterability, mixing properties, and ease of transport, such as uniform mixing.

器でさらに混合する方法も可能である。Here, the water-absorbing polymer and the aluminate are kneaded with the cement and the water, and at the same time, the viscosity increases.
It is necessary to carry out kneading in a short time, and it is usually preferable to use a continuous kneading mixer pump. In the present invention, when the pumping distance is long, the workability is impaired and the filling is apt to be insufficient. Therefore, it is necessary to separately pump and mix the water-absorbing polymer and the aluminate when producing concrete. In particular, it is preferable to add a water-absorbing polymer to a concrete material and pump it, and to separately pump aluminate, and to combine and mix them to produce concrete. As a method of merging and mixing, a method using a mixing tube such as a Y-shaped tube, a method using a double tube, and a method using an inlet piece for merging and mixing a suspension or an aqueous solution of an aluminate in a shower shape. Etc. Further, a method of further mixing with a static mixer in which a spiral mixer is set in the pipe after the combined mixing is also possible.

使用しても、その急結効果が向上しない。In the cement admixture of the present invention, it is more preferable to mix the aluminate with the water-absorbing polymer at a ratio of 5 to 20 parts with respect to 1 part. If the amount is less than 5 parts, strength developability may not be obtained, and even if the amount exceeds 20 parts, the quick-setting effect is not improved.

For comparison, a similar experiment was performed without using a water-absorbing polymer and an aluminate. The results are also shown in Table 1. In addition, when the water-absorbing polymer and the aluminate were mixed at the same time, the slump became 0 at the time of mixing, filling was difficult, and voids remained in some places.
