ルフレベリング床材が開発されている。[Conventional technology] In the past, concrete was poured and, after hardening, the surface was finished with cement mortar horizontally with a trowel, but in recent years, it has been possible to finish the concrete by simply pouring a highly fluid mixture onto the concrete surface. Self-leveling flooring materials have been developed that form a smooth surface due to the natural flow of the kneaded material.

In addition, since self-leveling flooring materials tend to generate cracks on their surfaces after curing, self-leveling flooring materials have been proposed in which an expanding material is mixed to prevent this from occurring (Japanese Patent Publication No. 5G-2).

Rapid hardening can be achieved by mixing summer-type anhydrite and adding it to the fast-hardening materials such as Huitong Portland cement, blast furnace cement, or their mixed cement.However, this hardened product exhibits drying shrinkage similar to ordinary cement. In order to reduce this, by further adding 5 to 15% by weight of summer-type anhydrite in the form of an IJ collection, it expands by about 10 to 30 x 101 in the early stage of curing, and reduces the subsequent drying shrinkage. In this case, the coarse powder summer-type anhydrite has good properties due to the by-product gypsum, hydrofluoric acid type I water stone and sweat. It has been found that the addition h() is within the range of 5 to 11 parts, and if these are outside this range, the above-mentioned length change characteristics are no longer maintained.

By mixing and adding 0 to 50 parts by weight, 5 to 15 parts by weight of coarse powder type anhydrite, and appropriate amounts of a setting retarder, fine aggregate, thickener, and water reducer, the rapid hardening self-leveling of the present invention can be obtained.

を肪止できることである。The long-term strength of the resulting cured product is increased by 1° by the calcium silicate hydrate in the Portland cement or mixed cement. However, the drying shrinkage of the obtained cured product is initially 1 to 2.
Expansion of approximately X10-' is observed, but as the material ages, the shrinkage decreases to a value of 1 degree, which is the same as that of Portland cement. Here, one feature of the present invention is the secondary addition of coarse-powdered summer-type anhydrite, as described above, a fast-hardening material obtained by mixing and pulverizing metallurgical slag and summer-type anhydrite, and Portland cement or While the hardened mixed cement exhibits only a small amount of expansion at its initial stage, the secondary addition of coarse-powdered summer-type anhydrite allows for expansion similar to that achieved when commercially available expansion materials are used. It has been found that drying shrinkage cracks can be suppressed by expanding the cured material at an extremely early stage.

推察される。Although it was not possible to clarify this phenomenon, in general, summer-type anhydrite, which is a by-product of the hydrofluoric acid manufacturing process, has large particles and is often aggregated in agglomerates. It is assumed that the reaction with highly reactive calcium aluminate and calcium hydroxide in the liquid phase locally increases the concentration of sulfur ions, causing the shape of the ettringite crystals to change and expand.

である。The degree of primary pulverization of the metallurgical slag must be such that it has a specific surface area of at least 3000 cm"/H, and then summer-type anhydrite is added and mixed into a powder to form a fast-hardening material. This is used as Portland cement. According to the present invention, if coarse-powder summer-type anhydrite is not added, the hardness increases rapidly and the short-term strength is increased up to one day after hardening. This is to reduce shrinkage during curing, and the type of summer-type anhydrite is not limited. By adding and mixing summer-type anhydrite, 1.
