First, the sand washing step 10 is to remove foreign matter (eg soil, stone, other dirt) contained in the sand,

Sand drying step 20 is to expand the washed sand to naturally dry the moisture contained in the sand to artificially control the amount of water contained in the sand,

The sand sorting step 30 is to classify the dried sand according to the particle size into three sand (eg less than 1mm) and ordinary sand (eg more than 1mm).

After the sand screening step (30) for classifying the three sand and the general sand as described above is subjected to the raw material mixing step 40,

The raw material mixing step 40 is a first mixing step 41 of forming a mixture of cement, water, glass fiber (length 3-4cm) in the general sand to form the lower layer 110 of the finishing material 100,

A second mixing step 42 for forming a mixture of fine sand, artificial stone, cement, high strength cement admixture, pigment, and water for forming the upper layer 120 of the finishing material 100,

A third mixing step 43 for forming a mixture of three sands, a white cement, a photoluminescent agent and a fluorescent agent, and water for forming the light emitting member 130,

It is subdivided into a fourth mixing step 44 for forming a mixture of fine sand, white cement, water, and pigment for forming the pattern member 140.

Then, the mixture by the third mixing step 43 is subjected to the light emitting member forming step 51 is molded in a separate molding mold and cured for a predetermined time,

The mixture by the fourth mixing step 44 is subjected to a pattern member forming step 52 that is molded in another separate molding mold and cured for a predetermined time,

The light emitting member 130 and the pattern member 140 obtained by the light emitting member forming step 51 and the pattern member forming step 52 have a mixture obtained by the first mixing step 41 and the second mixing step 42. In the product forming step 50 to be molded in the mold 150 is embedded in the lower portion of the mixture obtained by the second mixing step 42.

On the other hand, after the product forming step 50 is subjected to a bubble removing step 60,

Since the mixture contained in the mold 150 contains bubbles, the bubbles contained in the mixture are removed by a punching vibrator and a press method.

Then, after the product curing step 70 to cure in a steam curing room 7-8 hours,

After the curing is completed, the product is separated from the molding mold 140, and the product is demolished through the step of inverting the upper and lower parts 80,

The product is completed by going through the product polishing step 90 of removing the foreign matter from the surface of the product by polishing the collected product surface with a polishing machine.

Here, the product forming step 50 is performed in the order as shown in Figure 4,

First, as shown in FIG. 4A, the light emitting member 130 and the pattern member 140 are positioned at a specific position of the bottom of the molding mold 150 having a predetermined shape.

And, as shown in Figure 4b to fill a predetermined amount of the mixture obtained by the second mixing step 42 to form the upper layer 120 of the finishing material 100,

As shown in FIG. 4C, the mixture obtained by the first mixing step 41 of the upper surface of the deposition layer of the mixture by the second mixing step 42 is filled to a predetermined thickness to form the lower layer 110 of the finishing material 100. Will be.

At this time, when the mixture for forming the upper layer 120 is contained in the mold 150, the steel wire 121 of a predetermined length is embedded in the mixture, thereby reinforcing the compressive strength and the bending strength of the product. ,

In the upper layer 120, since the light emitting member 130 and the pattern member 140 may not be smoothly formed, the polishing operation 90 may be performed in consideration of an advantage in the product polishing step 90.

The present invention having the structure and manufacturing method as described above includes a high-strength cement admixture, steel wire 121 and the like to maintain a high compressive strength and flexural strength,

It contains alkali-resistant glass fiber, which maximizes the resistance and toughness against impact and cracks.

By removing the air bubbles contained in the mixture by vibrating and pressing method, the density between the raw material particles is increased to secure the disadvantages of general concrete products,

The light emitting member 130 including the photoluminescent agent and the fluorescent agent can guide the way to the people at the accident site in case of an accident such as fire or power failure, thereby minimizing human injury.

Pigment is colored on the entire product upper layer 120, and the pattern member 140 is made of a different color is provided so that it can deliver a more colorful and beautiful visual effect, so that the viewer can induce a different aesthetic sense .

On the other hand, the difference between the finish according to the present invention and the existing finish is summarized in Table 1.
