に使用することができなかった。On the other hand, at present, recycling of waste is an important issue in Japan from the viewpoint of environmental protection and effective use of resources, and many proposals have been made especially as means for treating and recycling glass waste. However, when glass is mixed with 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. Since a deterioration phenomenon such as expansion, peeling or cracking is caused, a large amount of glass waste material cannot be used as an aggregate of concrete solidified material.

ントの強化骨材として用い得ることも併せて見出した。At present, water-soluble synthetic resin emulsions are widely used for civil engineering and construction, as well as for paints, adhesives and film processing. In the civil engineering and construction fields, water-soluble synthetic resin emulsions include vinyl acetate emulsions, vinyl acetate / acrylic copolymer resin emulsions, vinyl acetate / ethylene copolymer resin emulsions, acrylic copolymer resin emulsions, acrylic / styrene copolymer resin emulsions, Using one or more of vinyl acetate / ethylene / vinyl chloride copolymer resins, kneading them with hydraulic cement, mainly cement, mortar,
It is used in places where little emphasis is required on shrinkage, such as admixtures, adhesives for tiles, and surface conditioners for cement. That is, the conventional polymer-based cement, the dimensions of the kneaded product having the above-mentioned composition at the production stage, and
The dimensions of the solidified material obtained by drying and solidification did not match, and the solidified material shrunk significantly with respect to the dimensions of the mold and had poor dimensional stability.

Since iO 4 ) 3 ] is a bipolar crystal, each of the finely ground fine particles has an independent bipolar crystal, and when it comes into contact with water, the water has an electric property due to a natural silicate mineral. Water (H 2 O) is decomposed into hydrogen ions (H + ) and hydroxyl ions (OH − ). At that time, the positive ions (H + ) are released as hydrogen gas (H 2 ) because of their high ion mobility, but the hydroxide ions (OH − ) combine with the surrounding water molecules (H 2 O) [ H 2 O + OH − = (H 3 O 2 ) − ], hydroxyl ion (H

When mixed with the mixed water-soluble synthetic resin emulsion, the surfactant effect of the mixed water-soluble synthetic resin emulsion is promoted. As a result, the affinity between the hydraulic cement and the mixed water-soluble resin component is increased, and a solidified body in which the cement crystalline composition and the mixed water-soluble synthetic resin are densely entangled with each other has excellent dimensional stability, excellent bending characteristics and compression. Show characteristics. When the particle size of the fine particles of the natural silicate mineral is 50 μm or less,
It was found that the surfactant effect was further promoted. Furthermore, when fine glass particles are blended, a resin film is formed between the cement crystalline composition and the glass due to the surface active effect of the mixed water-soluble synthetic resin emulsion, and the glass directly contacts the cement crystalline composition. It was found that the reaction between cement and glass was prevented, so that a glass polymer cement solidified material having extremely high strength was obtained even when a large amount of glass powder was added.

Further, in the present invention, a large amount of glass particles can be added as an aggregate, so that glass waste, which has recently become a problem, can be effectively used as a resource.
