Above all, it is difficult to collect and secure a collection place for used glass waste materials mainly used as household food and beverage containers, and there is an urgent need for the national and local governments to reuse them. As a recycling method of the waste glass waste which has been already proposed, there is a method of mixing the waste glass with a hardening agent, asphalt, cement, or the like, and using it as a road pavement or reclaiming a digging site as a solidified product (Japanese Patent Laid-Open No. 5-1).

About 15%, and about 3 to 5% of the total amount in the use of a structure in which glass beads are mixed in ready-mixed concrete mixed with cement, sand and gravel as disclosed in JP-A-6-340458 for light reflection. Could not be mixed. Although effective in terms of reusing glass waste, the effect was small in terms of using a large amount of glass waste due to the small amount of glass contamination. Originally, when waste glass waste is mixed into hydraulic cement, the silicic acid component of the glass composition causes a chemical reaction with the alkali component of the hydraulic cement (alkali-aggregate reaction), causing a change in composition in the cement crystal and expansion, It causes deterioration phenomena such as peeling and cracking. Therefore, a large amount of waste glass waste could not be reused as aggregate for concrete.

造体）となることが見出された。In the present invention, utilizing this characteristic, fine particles and fine glass particles of a natural silicate mineral pulverized as a reinforcing aggregate are put into a hydraulic cement, and mixed with a water-soluble synthetic resin emulsion. The surfactant effect of the hydrophilic synthetic resin emulsion is promoted. As a result, the affinity between the hydraulic cement and the water-soluble synthetic resin in the emulsion is increased, and a copolymer in which the crystalline structure of the cement and the water-soluble synthetic resin are tightly entangled is formed, and high bending properties and compression properties are exhibited. The particle size of the fine particles of the natural silicate mineral is 50 μm.
It was found that the surface active effect was further promoted when the value was less than m. Further, the water-soluble synthetic resin emulsion forms a resin film between the cement crystalline composition and the fine glass powder due to the surfactant effect of water. As a result, a state in which the fine glass particles do not directly contact the cement crystalline composition,
It was found that a reaction between cement and glass was prevented, and a solidified body (floor structure) with extremely high strength was obtained even when a large amount of fine glass particles were added. As described above, conventionally, when waste glass waste was mixed with hydraulic cement, the strength of the solidified body was reduced. However, the synergistic effect of the fine particles of the crushed natural silicate mineral and the water-soluble synthetic resin emulsion was observed. As a result, it was found that a high-strength solidified body (floor structure) was obtained even when a large amount of glass waste was used.

This portion causes a particularly excellent appearance. More specifically, since the fine glass powder particles exposed on the surface are irregular in shape and are transparent to varying degrees, the part may appear hollow or reflect light. There is also an expensive natural stone-like aesthetic. Fine glass powder particles are also partially exposed on the surface before polishing finish, but it is a pear ground as a whole and the exposed portion of fine glass powder particles is not a flat surface The feeling of nobility becomes faint.

きる。As described above, the floor structure of the present invention has the following features.
It is made by pouring a polymer cement composition containing a large amount of fine glass particles and polishing and finishing the hardened surface. It can be reused effectively. Further, as a conventional method of using waste glass waste, there is also known a method of reusing a waste glass waste into a compact such as a tile by pulverizing the waste glass dust into fine powder, adding an appropriate component, heating and firing at a high temperature. However, such a recycling method involving calcination promotes global warming because generation of CO 2 is inevitable. On the other hand, the present invention does not perform such calcination, thus reducing CO 2 and contributing to prevention of global warming. Further, the floor structure of the present invention has extremely high strength, and fine glass powder particles are partially exposed on the surface thereof, thereby exhibiting an expensive natural stone-like excellent aesthetic appearance. In addition, as described above, the floor structure of the conventional structure in which natural stone or processed stone is processed into a tile shape and pasted, the tile is extremely expensive, and the construction is extremely troublesome. As for the structure, the raw material is a large amount of fine glass powder particles as described above, and at the time of its construction, it only performs the usual work of casting and surface polishing finish,
Construction can be performed very easily, and construction costs can be reduced.
