ために、コンクリ−１・硬化体表面に多数分散している
気孔を完全に目止めすることはできなかった。それゆえ
施釉コンクリート硬化体表面のピンボールを完全になく
すことができないという欠点があった。However, since this sealing work has traditionally been done manually, it has not been possible to completely seal the large number of pores dispersed on the surface of the hardened concrete 1. Therefore, there is a drawback that pinballs on the surface of the hardened glazed concrete cannot be completely eliminated.

収率が悪かった。Therefore, the present inventors proposed a manufacturing method that does not cause pinholes in advance by using a water-cement ratio (W/C) of 50 to 100%.
A mortar mixture with a sand-cement ratio (S/C) of 160 to 420% is poured into a mold, compacted by vibration, floating water is removed, and a surface layer of several fins is formed. A hardened plate-shaped glazed concrete body with a two-layer structure in which a mixture of mortar is poured, compacted by vibration to form a base layer, formed, dried, the surface layer is glazed, fired, and cooled. proposed a manufacturing method. (Japanese Patent Application No. 6l-238001) Problems to be Solved by the C0 Invention According to the method described above, the problem of pinball can be solved to a certain extent. The exterior material has a base layer that maintains the required bending strength, and a surface layer that eliminates the above-mentioned drawbacks of the glazed surface. However, because the residual length change rate of the base concrete or mortar after firing and cooling is smaller than that of the surface mortar, the exterior material warps toward the base concrete, and JIS A6501
In some cases, the tolerance (curvature - 5m+n) specified for building components (concrete 1/wall panel) was exceeded, resulting in poor product yield.

Problems to Solve the Problems In order to solve the above-mentioned drawbacks, the present inventors formed the surface layer and the base layer, and then poured a mortar mixture of a specific composition to form the back layer. It was discovered that warpage was significantly improved by integrally molding the layers, and based on this, the present invention described below was completed.

The width is approximately (30-150) x (30-150)
Suitable for manufacturing plate-shaped glazed concrete 1-hardened bodies with a size of cm. The cured product has three layers, a surface layer, a base layer, and a back layer, which are successively cast using mortar kneaded material or concrete 1 to kneaded material, and are integrally molded.Finally, the surface layer surface is glazed. Above 3
The roles of the layers are as follows. In other words, the surface layer is made of a mortar mixture that prevents pinholes from forming in the glaze.
The base layer is made of a mixed concrete or mortar mixture that can provide the bending strength required for a hardened plate, and the back layer is made of a specific blend to suppress warping that occurs when the surface and base layers are cooled after firing. It is made from mortar mixture. Providing this backing layer is most important in the present invention.

分行き渡らず、強度が弱くなり実用的でない。The mixing ratio of cement in the mortar mixture for forming the surface layer is at least such that the space between the sand is filled with cement during vibration compaction. It is desirable to add a relatively large amount of kneading water so that it can be easily defoamed during vibration compaction. W/

It is 0-300%. W/C less than 50% or S
If /C is less than 160%, compaction will not be sufficient and W
If /C exceeds 100% or S/C exceeds 420%, the cement particles will not be sufficiently distributed between the sands due to poor mixing, resulting in weakened strength and impractical.

なお、表層および裏層の各モルタル原料を混練する際、
強度増進剤、高性能減水剤、増粘剤、消泡剤等を適宜配
合することは差支えない。In addition, when kneading each mortar raw material for the surface layer and back layer,
There is no problem in adding strength enhancers, high performance water reducers, thickeners, antifoaming agents, etc. as appropriate.

By applying a glaze to the surface layer of the hardened body by a conventional method, firing it, cooling it, and subjecting it to a hydration reaction, a glazed hardened concrete body with less warpage or less than a tolerance can be obtained. There is also no pinball on the glazed surface.
この場合、水和反応の前に再ひ施釉して、焼成。In this case, it is reglazed and fired before the hydration reaction.

Effects of the invention The present invention divides the hardened part of the plate-shaped glazed concrete IJ-1 hardened body into a surface layer, a base layer, and a back layer, and sequentially coats the hardened parts of the plate-shaped glazed concrete IJ-1 into a surface layer, a base layer, and a back layer using mortar mixes, concrete mixes, etc., each having a suitable composition. This is the J-method, in which the product is poured, molded in one piece, and then glazed.This is a manufacturing method that allows the warpage of the product to be kept within the tolerance. As a result, the torsion is improved, and the yield of the cured product is greatly improved. Furthermore, by using a kneaded material with a specific composition for surface molding, it is possible to create beautiful glazes without pinballing.
