2. Description of the Related Art When cracks occur on a colored floor such as a ferrocon-finished floor, the appearance of the floor is extremely deteriorated. Each had problems in appearance and performance. Rubbing method of ferrocon powder This is a repair method in which the repair powder is stiffened with a special acrylic adhesion enhancer and rubbed into cracks.However, the surface of cracks can be hidden, but there is a difficulty in filling depth. Lacks reliability in performance. U-cut sealing method This is a repair method in which a U-cut of about 5 mm is made, sealed with a special sealing material, and cut with a seal knife after curing.
The cuts make the cracks more noticeable and the appearance worse, and the repair performance is not perfect. Similar to the ferrocon powder rubbing method, this is a repair method in which the repair powder is kneaded with an emulsion type epoxy resin and rubbed into cracks.
Due to the high viscosity, construction is difficult and the appearance is difficult, and in addition, the filling depth is difficult, so the reliability is poor in terms of performance.

Hereinafter, embodiments of the present invention will be described with reference to experimental results and the like.

FIG. 1 is a plan view showing the application of a crack repairing method according to the present invention to a colored floor. In the figure, 10 is
It is a colored floor finished with ferrocon, color cleat, etc., and cracks 1 are generated on the floor surface. Repair work is
It starts by providing injection holes 2 at a pitch of 100 to 200 mm along crack 1 as shown. The injection hole is formed by pasting the curing tape 3 at a predetermined position and sealing the other cracked surface with the quick-setting cement 4. The curing hole 3 is peeled off to form the injection hole 2.

The repair work is performed by subsequently injecting a repair material from the above-mentioned injection hole, and specific embodiments thereof will be described below in order. The crack 1 is washed with water to remove dirt and dust in the crack. A curing paper tape is applied along the crack 1 at a position where the injection hole 2 is provided at a pitch of 100 to 200. Cracked portions other than the injection hole are sealed with a quick setting cement 4 which is colored by mixing 20 to 40% of an inorganic pigment of the same color as the ferrocon on the floor. From the injection hole 2, a repair agent produced by kneading 5 to 10% of an inorganic pigment of the same color as the ferrocon on the floor and mixing and coloring the blast furnace fine powder cement with water at a ratio of about 80% or less is injected by a direct method. The injection of the repair agent is performed in order from the end, and the injection hole after the injection is sealed with the quick-setting cement. After a few days of curing, the sealed quick setting cement is removed with an electric wire brush.

[Table 2]

As shown in Table 2, the sealing material was applied with various amounts of inorganic pigments changed to 10 to 40%, but the workability was not changed and all were good. Injection was carried out while changing the inorganic pigment to 0.5% and 1.0%, but there was no change in the workability. Even with regard to the quality of the floor surface, when the inorganic pigment is mixed in the seal material by 20% or more in order to make the color of the seal material inconspicuous,
The color and the like became appropriate, and the quality of the floor surface was good. In addition, regarding the crack width and the injection depth, it is possible to sufficiently inject a crack having a depth of 95 to 110 mm by setting the mixing amount of water to 70% with respect to a crack having a durability of 0.3 mm or more where durability is a problem. If the durability is relatively unimportant, with emphasis on appearance, filling with a crack width of about 0.2 mm can be achieved by setting the mixing amount of water to 80%.
