In addition to the function of preventing the deterioration of the cement due to alkali, the kneading with the colored abrasion-resistant mixed powder plays a role of increasing the adhesion to the cement, the abrasion-resistant aggregate, the pigment, and the fiber. In addition, the hardness of the mortar surface is increased by mixing the wear-resistant aggregate to suppress the surface wear. Further, by adding a dispersant, the cement / water ratio is set to a low value, and the occurrence of cement efflorescence due to breathing is suppressed, thereby playing a role of forming a floor having a uniform color finish.

で耐衝撃性に優れている。Further, since the bending strength of the mortar is improved by the reinforcing effect of various fibers, the occurrence of cracks can be suppressed. In addition, since various fibers are immersed in a water-soluble synthetic resin or synthetic rubber emulsion and filled in a container, the surface of each fiber is formed with a protective film of resin, While preventing the deterioration of the cement due to alkali, the adhesive force with the cement, wear-resistant aggregate, and pigment is also improved. Further, since the mortar is reinforced by various fibers, an impact force is applied and the matrix of the fibers in the mortar disperses the impact force, so that the mortar is excellent in impact resistance.

提供できる。According to the above-mentioned FRC construction method for a colored abrasion-resistant floor using the pre-mixed composition for FRC of the present invention, a uniform colored finish can be obtained, the generation of cracks can be suppressed, and the resistance to cracks can be reduced. It is possible to construct a floor which is excellent in impact resistance and abrasion resistance and has a suitable non-slip property. In addition, it is possible to provide a pre-mixed composition for FRC that can perform the FRC construction method of this floor in a favorable manner.

面の摩耗を抑制することができる。Specifically, since a water-soluble synthetic resin or a synthetic rubber emulsion is used, in a pre-mixed composition for FRC, since various fibers are immersed in the resin solution, a protective film is formed on the fiber surface. When formed, the cement can be prevented from being deteriorated by alkali, and in the kneading with the colored abrasion-resistant mixed powder, the adhesion to the cement, the abrasion-resistant aggregate, the pigment, and the fiber can be increased. Further, the hardness of the mortar surface can be increased by mixing the wear-resistant aggregate, and the wear of the surface can be suppressed.

Therefore, the cement / water ratio can be accurately controlled. Further, by adding a dispersing agent, the cement / water ratio is set low, and the occurrence of cement effluent phenomenon due to breathing is suppressed, so that a floor having a uniform colored finish can be formed.
