In the present invention, in addition to conventional gravel, sand, and silica sand as inorganic aggregates, or all of them are cullet, the surface layer forming the design surface is brushed to expose the cullet to the surface layer. With such a structure, a new texture and a color tone similar to that of natural stone can be exhibited, and the cullet exposed on the surface layer can also exert a sufficient luster.

度を高める点から６０％以上とする。The cullet is classified into those having a particle size of 1 to 5 mm and those having a particle size of less than 1 mm, and those having a particle size of 1 to 5 mm are edgeless for improving the binding and safety. It is preferable to perform processing. Further, impact crushing cullets can be used as those having a particle size of less than 1 mm. In addition, since the recycled cullet can be used, there is an advantage that resource saving and production cost can be reduced. These cullets are 20% to 60% by weight of the cullet having a particle size of 1 to 5 mm.
The cullet having a particle size of less than 1 mm is contained in the range of 10 to 30%. If the amount is less than these ranges, it is difficult to exhibit a sufficient color tone like natural stone, and if the amount is large, the cullet in the surface layer portion is likely to fall off and scatter. The actual rate of the cullet having a grain size of 1 to 5 mm is set to 60% or more from the viewpoint of preventing the cullet from falling off and scattering and increasing the strength as a block.

Moreover, the ratio of water / cement is 0.2 to
It is preferable to mix them to be 0.4. If this ratio is less than 0.2, the ratio of cement increases and it becomes difficult to sufficiently expose the cullet to the surface layer portion. On the other hand, if this ratio is more than 0.4, sufficient adhesive strength as a block cannot be obtained. It is.

A cullet having a weight of 0% and a particle size of less than 1 mm is mixed with 10 to 30% by weight, and a predetermined amount of cement, water and an organic resin are mixed and pressed to form a block having a predetermined shape. Next, curing for one week to form a concrete block is basically the same as the conventional molding process of this type. The present invention is characterized in that the surface layer forming the design surface is subsequently brushed with a polishing brush containing an abrasive so that the cullet is exposed on the surface layer. That is, by removing the cement paste adhering to the surface of the cullet by the brushing treatment, the cullet is exposed to the surface layer to exhibit an excellent color tone and to sufficiently exhibit the gloss of the cullet. In this brushing treatment, in order for the cullet to remain on the surface layer portion of the block body without peeling, the cullet content is set to the predetermined amount as described above, and the water / cement ratio is set to 0.2 to 0. It is preferable to secure an appropriate adhesive force in the range of 0.4.

It is preferable to perform the brushing treatment because it is possible to prevent a reduction in polishing force and the generation of rust due to deformation during use such as a metal brush. In addition, this brushing process is dry
Of course, any of the wet methods can be applied.

In the table, cullet A means edge-treated particles having a particle size of 1 to 5 mm, cullet B means particles having a particle size of less than 1 mm, and a waterproofing agent is aluminum polymerized oil, and a water reducing agent is formalin naphthalenesulfonate. A polycarboxylic acid-based condensate and dispersant were used.
Then, the surface layer of the obtained block body was subjected to a brushing treatment using a resin brush made of 612 nylon and having a diameter of about 1.0 mm and containing a polishing material (SiC♯80), and the concrete block was formed. Obtained. As a result, it was confirmed that the cement was removed and the cullet was exposed on the surface layer portion of each of the samples, and it was confirmed that the cullet had sufficient gloss and reflected light well. In addition, the number of drops (n = 10) of the cullet from the surface of the cullet due to the brushing treatment was checked, and it was confirmed that there was no problem. Further, the smoothness of the surface layer, the bending strength, etc. It was confirmed that the block had sufficient quality. In addition, it was found from No. 6 in the examples that an increase in the content of cullet A tended to increase the number of cullet drops, and it was confirmed that the upper limit was 60% by weight. As is apparent from the comparative examples in Table 2, when cullet A having a performance rate of 60% or less was used as cullet A, the number of cullet drops increased, and sufficient gloss in the surface layer portion could not be obtained. found.
