Description

Glass Concrete Tile Manufacturing Method

The present invention crushes the waste glass, such as glass bottles, glass plates, etc. that can be commonly found in the surroundings instead of artificial stone (seamstone) in portland cement or white cement, crushed glass and weatherable, inorganic pigments without strong color change And mold formwork which can give vibration and press compaction in the usual way by mixing the material of high fluidizing agent neutralized with naphthalin as the main raw material to remove voids and external voids in concrete tiles and improve productivity and strength. Method of manufacturing glass concrete tiles with low cost and shiny surface with diffused reflection of glass, beautiful color and surface with high strength by primary polishing and secondary polishing by light plate after curing in concrete It is about.

Conventionally, terrazzo plates, terrazzo tiles or elected applications 73-155, 79-71, which are produced by mixing and curing artificial stone (seamstone), that is, marble and granite crushed aggregates in cement. , 85-71, etc. are manufactured by crushing, curing and grinding marble and granite in cement. Artificial stone (marite), that is, marble and granite are expensive, difficult to purchase in large quantities, and have a low gloss. It is not so beautiful and easily broken.

In view of this point, the present invention pulverizes waste glass bottles, glass plates, etc., which can be purchased in large quantities at low prices, and mixes them with ordinary Portland cement or white cement, and mixes inorganic pigments with a high fluidizing agent to cure them in metal formwork. After polishing with a polisher and a light plate, the surface is diffused by the glass and the gloss is increased, the appearance is more beautiful and the strength is maintained by the high fluidizing agent, so it is not easily broken and the color can be freely blended and the price is low. It will be described in detail as to provide a glass concrete tile as follows.

The present invention is to crush the waste glass bottles, glass plates, etc. that can be easily obtained from the surroundings and mix them with cement. Typically, glass is poorly bonded with cement, so that the strength is weak after mixing and curing, and the glass fragments are cut during the cutting and polishing process. In order to prevent this, the glass itself is crushed with a small crusher, and when it is used for sorting, the glass surface becomes large when crushing, and the adhesive strength with cement is strong. Pulverize. Glass can have different particles depending on the shape required, but only 15mm or less can be used. That is, in the case of using less than 15mm, and in the case of using less than 5mm, there are cases in which particles from 15mm to 5mm may be used. In this case, the characteristics of each structure may vary depending on the type of use. The type of cement is determined in the most economical range depending on the color required. If the color of the pigment is gray, black and red, it is usually portland cement. If it is blue, green and yellow color, it is white pigment. The amount of cement can be reduced and the product can be made economically. The amount of cement is decided by the compounding design so that the compressive strength is 200Kg / ㎠ or more. Pigments used in glass concrete tiles include organic pigments (phthalocyanic or shani) and inorganic pigments (iron oxide-red, iron oxide-sulfur, titanium dioxide, chromium oxide, zinc oxide, Ultramarine Blue, Prussian Blue). The color is dark and diverse, but there are some kinds of weather resistance poor. Inorganic pigments are products produced by oxidizing metal materials and reviving at 1000-1500 ℃. They are not oxidized again and are colored in cement and hardly discolored.

However, iron oxides produced in domestic steel mills have been cleaned of chlorine with hydrochloric acid and have not been calcined with materials extracted and processed from the rust. Therefore, discoloration and deformation are so severe that pigments using iron oxide generally discolor and deform. Therefore, the pigment uses inorganic pigment which is oxidized metal material and calcined at 1000 ° -1500 ℃. When excessively used in consideration of the color of the pigment and the color of concrete, the strength of cement increases because the strength of cement decreases slightly during curing. As the amount of glass used decreases, the surface may not be in the desired shape. It is used within 5% of the weight of cement, and the high fluidizing agent used for glass concrete tiles has water and cement ratio of 25% or more. Crystallization is used in the range of 15㎝, and the proper usage is within 2% of the cement weight High fluidizing agent increases the strength by reducing water to 15-20% and disperses cement and pigment to improve color distribution and gives fluidity to concrete. As it flows, every corner of the mold formwork fills the surface, and the surface is clean and there is no internal void.

Glass fragments of 15mm or less selected in this way, mineral pigments within 5% of the weight of cement and cement, water and cement ratio are 25% or more, and the slump is within the range of 2% of the weight of cement so that the slump ranges from 5-15cm. Determine and mix the determined material to be over 200Kg / ㎠ compressive strength, and place it in mold form as usual and press and cure by vibrator compaction and pressing device. Curing is performed at room temperature above 15 ℃ in mold form. Curing should be maintained for more than 10 hours. The spray curing after dismantling the form will cure at least 15 days at room temperature above 15 ℃, at least 1 day at above 15 ℃ in case of underwater curing, and at least 65 hours in case of steam curing.

In this way, after curing, polishing is performed. Mix the same color pigment and cement according to the surface condition, clean up the surface by adding water and a fastener, and cure it. Secondary polishing is performed to obtain glass concrete tiles. If the tile thickness is 15mm or more when manufacturing the glass concrete tile, it is economical to cast only 10mm with glass concrete and make the rest part, ie, the back layer, as ordinary concrete with the same strength as the surface layer. The material for the back layer is usually made of clean and strong stone mill sand of Portland cement and general aggregate (up to 15mm of coarse aggregate), and the amount of each material is decided so that the compressive strength is more than 200㎏ / ㎠ and the slump is 5-15㎝. The surface layer is poured first, followed by the back layer.

Example 1

In case of making 28 pieces of glass concrete tiles with 300 × 300 × 30mm, and making the product to be cut by diamond cutting machine with the background color as red, white glass is used, and the glass size is 15mm sieve flour. At this time, prepare the formwork 300 × 300 × 1000㎜, mix cement for 4 minutes with Portland cement, 134.5kg of glass, 0.7kg of pigment for 0.5 minutes, add 15.7kg of water, and mix 0.5kg of the high softening agent. After adding for 1 minute, add it to the metal mold coated with the demolding agent, and compact it by vibrating and pressurizing device in the usual way. Cut 28 pieces of diamond cutters at 30mm intervals (about 15% loss). If there are scratches on the surface after cutting, mix the red pigment with mortar, add a quickener, and apply the surface with a brush. After curing and curing, the primary polishing with a concrete polisher and second polishing with a light plate to produce the glass concrete tiles of the present invention.

Example 2

When glass concrete tiles are made of 400 × 400 × 40㎜ and the ground color is dark gray, light blue glass should be used and the polishing tile should be used for internal floor tiles. At this time, the surface layer and the back layer is divided into 10 mm thick and the back layer is 30 mm. In addition, the surface layer is usually made of Portland cement, 880 g of cement, 2390 g of glass, and 5.6 g of pigment are mixed for about 0.5 minutes, 282 g of water is mixed for 0.5 minutes, and 8.8 g of a high softening agent is mixed for 1 minute. After placing the mold in the metal mold coated with the demolding agent in the usual way, and compacted by vibration and pressure device, the back layer is mixed with 2256g of cement, 3298g of sand, 5045g of gravel and 912g for 1 minute, and then placed on glass concrete. It is compacted by vibrating and pressurizing device (used as a floor surface layer). After 10 hours in a room at 15 ℃ as usual, spray curing at 20 ℃ for 3 days, and then first polished with concrete polisher It is used to produce a glass concrete tile of the present invention by the secondary polishing with a light plate as needed to give a light.

The present invention uses the waste glass as described above, using the inorganic pigment calcined at 1000 ℃-1500 ℃ without discoloration and deformation, high strength and high dispersion of the high fluidizing agent as a product using more than 200kg / ㎠ Because of the balance between the surface gloss due to the diffuse reflection of the glass and the concrete color according to the use of the pigment, the appearance is more beautiful and cheaper than other products.
