ンクリートが未硬化の段階で耐摩耗性混合粉体を散布
し、平滑に仕上げて硬化させる方法である。That is, since cracking and efflorescence (white flower) are likely to occur in ordinary concrete due to various factors, resin concrete mixed with an organic synthetic polymer emulsion is used in order to suppress this, and this resin concrete is not yet used. This is a method in which the abrasion-resistant mixed powder is sprinkled at the curing stage to finish the surface smooth and cure.

った。In the conventional method of spraying the inorganic colored cement powder on the surface of the green concrete, it is a matter of course that the powder material is uniformly sprayed, and the variation of the breathing water of the base concrete is a problem. That is, when the water content is excessive, efflorescence occurs, and when the water content is too small, the trowel cannot be pressed and water is sprayed, which causes efflorescence. Furthermore, uneven distribution of water causes a difference in drying shrinkage of the cement, which may cause a crack having a width of 2 to 3 mm, which makes it difficult to see the bending method.

合粉体を併用することが効果があることが分かった。The surface of the wear resistant coating floor due to the spraying of the hydraulic powder material is apt to cause cracks, efflorescence (white flower) and uneven color due to shrinkage of cement.
In order to prevent these from occurring, the concrete itself should be made with a low water ratio (color unevenness, white sinter and cracks are reduced), or moisture should be uniformly supplied to the abrasion resistant mixed powder, so that concrete mixed with emulsion mixed abrasion resistance It has been found that the combined use of the mixed powder having the property is effective.

The point is to provide a method for constructing a wear-resistant coated floor that does not cause lacquer.

分が均一になっていることがポイントとなる。In the present invention, by mixing a synthetic resin emulsion into concrete or mortar, a certain amount of breathing water appears on the surface, and a proper amount of water is pumped by the capillary phenomenon to cause abrasion resistance. The feature is that a proper amount of water is supplied to the powder and secondary sinter of the colored cement is prevented. Also,
The reason why there is little breathing water is that the emulsifier of the resin emulsion contributes to the water reduction effect of concrete (20-3
This is because the surface water content of concrete or mortar is uniform.

た。Example 3 Ordinary concrete as shown in the concrete composition table of Table 3 was manufactured in a ready-mixed concrete factory and transported to the site, and then the EVA emulsion shown in Table 4 was put in the drum of the mixer truck at the site. High-speed stirring was carried out for 5 minutes to obtain emulsion-mixed concrete, which was poured as soil concrete, immediately smoothed on the uneven surface, sprayed with wear-resistant powder shown in Table 2, and finished with a metal trowel.

るような表層剥離現象は防止できる。EFFECTS OF THE INVENTION Since cracks and efflorescence hardly occur in the wear resistant coated floor using the emulsion-mixed concrete or emulsion-mixed mortar of the present invention, the effect of preventing deterioration of aesthetics and prevention of troubles in use is obtained. It's a lot. Further, the emulsion-mixed concrete or the emulsion-mixed mortar has an effect of preventing the permeation of oil and the like. Furthermore, since the adhesion between the emulsion-mixed concrete or the emulsion-mixed mortar and the wear-resistant powder layer is good, the peeling phenomenon of the surface layer which can be seen in ordinary concrete can be prevented.
