The present invention relates to a cement-based self-leveling material composition that exhibits excellent fluidity when mixed with water, forms a uniform smooth surface especially as a material for cast flooring, and hardens in a short time to achieve the desired initial strength. The purpose of the present invention is to provide a cement-based self-leveling material that can be developed. Conventionally, after concrete is poured and hardened, its surface is leveled (smoothed) with cement mortar using a metal trowel, which requires the labor and time of skilled plasterers to finish. In contrast, in recent years,
A cement-based self-leveling material has been developed that forms a smooth surface by simply pouring a highly fluid kneaded material onto the concrete surface due to the natural flow of the kneaded material. In other words, such cement-based self-leveling materials are required to have excellent fluidity necessary for pouring, to form a uniform smooth surface through natural flow, and to harden within an appropriate amount of time to quickly develop strength. . Generally, when a cement-based self-leveling material is mixed with an increased amount of water, it becomes softer and its fluidity (flow value) increases. However, when the amount of mixing water increases, a decrease in the initial strength (1 to 2 days old) of the cement-based self-leveling material is unavoidable.
In addition, the amount of breathing increases, which impairs workability and construction efficiency. Therefore, cement-based self-leveling materials have a fluidity ( )゜− higher than a specified level.
It is desirable that the initial strength should not decrease as much as possible while at the same time exhibiting the desired value. In view of the above, the present inventors conducted intensive research and found that by blending chlordane into a conventional cement mortar composition, a desired cement self-leveling system with a small decrease in initial strength despite an increase in flow value can be achieved. The present invention has been provided based on the discovery that a material can be obtained. That is, the present invention is a cement-based self-leveling material composition made by blending an indene compound into a cement-based mortar composition, which exhibits excellent fluidity when mixed with water, and has a flow value of 19 cm or more and a desired initial level. It can demonstrate strength. As the cement mortar composition of the present invention, conventionally known ones can be used without particular limitation, such as Portland cement, fly ash, and other non-crack-producing plasters containing powdery amorphous silica and (dihydrate) gypsum as main components. Cement compositions are preferred. Generally 100 parts by weight of Portland cement, 5 to 45 parts by weight of fly ash and 1 to 44 parts by weight of gypsum
A cement composition consisting of parts by weight is used. In the cement mortar composition as described above, one or more general additives such as aggregates, dispersants, and water retention agents may be added as other components, as required. In addition to ordinary fine aggregates such as sea sand, river sand, and crushed stone, the aggregates are preferably slag, whitebait, causal sand, and perlite, which have a water absorption rate of 2 to 20% and a particle size of 5 mm.
By using the following microporous special fine aggregate containing silica and alumina, which are mostly amorphous materials, it is possible to obtain a cement-based self-leveling material that does not cause cracks for a long period of time. Also, known water reducing agents and/or AE agents are used as dispersants, such as aryl sulfonates, alkylnaphthalene sulfonates, lignin sulfonates, phosphate ester surfactants, and melamine sulfonate complexes. (condensate), naphthalene sulfonate condensate, polyalkylaryl sulfonate, highly condensed triazine compounds, etc., or a combination of two or more thereof may be used. Particularly, in the cementitious self-leveling material composition of the present invention, it is extremely effective to combine at least a dispersant of a highly condensed triazine compound or a melamine sulfonate compound together with the indene compound described below. The blending ratio of such a dispersant may generally be 0.1 to 0.5% by weight based on the main components of the above-mentioned cement mortar composition. Furthermore, cellulose-based, vinyl-based, and acrylic-based compounds are generally used as water-retaining agents, but celluloses such as methylcellulose, hydroxyethylcellulose, hydroxypropylcellulose, methylhydroxyethylcellulose, and hydroxypropylmethylcellulose are preferably used in cement-based mortar compositions. It is generally used in an amount of 0.1 to 5% by weight based on the main component of the product. In addition, known additives such as dispersion aids, antifoaming agents, hardening modifiers, viscosity modifiers, and antifreezing agents, which are generally blended in cement-based mortar compositions, can also be blended as appropriate. Corresponding cement-based self-leveling materials have already been proposed, which are prepared by selecting various additives such as dispersions for the above-mentioned cement-based mortar compositions. Therefore, in the present invention, it is extremely important to blend an indene compound into the cement-based mortar composition without any particular restriction in order to exhibit desired fluidity and initial strength. The indene compounds used in the present invention are not limited to chlordane shown in the examples, but also chlorane (Hexachlor), heptachlor,
In addition to various chlorine derivatives such as Nonachlor, chlorine-free compounds having the same structure as indane or indene compounds, and derivatives thereof can also be used. The larger the indene compound is added to the mortar composition, the more effective the fluidity and initial strength of the resulting self-leveling material can be. 0.005-4% by weight, preferably 0.01-2% by weight
is sufficient. The order in which the indene compounds are added to the cement mortar composition of the present invention is not particularly limited. For example, when used as a cement-based self-leveling material, it is convenient to mix a predetermined proportion of an indene compound into a cement-based mortar composition prepared in advance. Furthermore, when a liquid dispersant or the like is used, it is also preferable to prepare the dispersant and the indene compound in advance and mix them into the cement mortar composition in the same manner as above. Of course, the cement-based self-leveling composition may be prepared by simultaneously blending the cement-based mortar composition and the indene compound. Examples are shown below, but the present invention is not limited to these Examples in any way. Example 1 Using Portland cement (manufactured by Tokuyama Soda Co., Ltd.), a cement mortar composition was prepared in the proportions shown in Table 1 below.

Each cement-based self-leveling material shown in Table 2 was prepared in combination with 0.4% by weight or 0.01% by weight of chlordane (Everwood Emulsion C-200, manufactured by Shinto Paint Co., Ltd.). Next, each cement-based self-leveling material shown in Table 2 was mixed with a predetermined amount of water to determine the fluidity (flow value) and initial strength (material age 1 to 2 days) of a 30% slurry.
was measured. The flow value test method is to place a vinyl chloride pipe (50A, inner diameter 50mm, height 51mm) on polished glass (5mm thick), fill it with the kneaded slurry, pull up the pipe, and check the spread of the kneaded slurry. After it came to rest, the diameters (mm) in two perpendicular directions were measured and the average value was determined. In addition, the initial strength was measured for 24 hours (1 day) and 48 hours (2 hours) using test specimens based on the JISR5201-9 strength test.
