Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は、モルタル乃至コンクリート（以下モルタルと
略する）下地の表面を化粧仕上げするための仕上げ材に
関する。TECHNICAL FIELD The present invention relates to a finishing material for applying a decorative finish to the surface of a mortar or concrete (hereinafter abbreviated as mortar) substrate.
（従来の技術） 下地モルタルを打設後、余剰水が上がる前にその表面に
セメント、骨材及び顔料等を配合してなる仕上げモルタ
ルを塗布し、この仕上げモルタルを余剰水で下地モルタ
ルと一体化し、床等の化粧表層を形成する工法が従来行
われている。(Prior art) After placing the base mortar and before surplus water rises, apply finish mortar with cement, aggregate, pigment, etc. on its surface, and integrate this finish mortar with the base mortar with excess water. Conventionally, a method of forming a decorative surface layer such as a floor is used.
（発明が解決しようとする課題） しかし、余剰水と共に下地からCa（OH）２等のアルカリ
分が表出し、空気中のCO2と接触するため、施工後に仕
上げ材の表面が白化することがあり、後でワックスを塗
り付けて手直ししなければならない等の問題があった。(Problems to be solved by the invention) However, since alkaline components such as Ca (OH) 2 are exposed from the base together with excess water and come into contact with CO 2 in the air, the surface of the finishing material may be whitened after construction. However, there was a problem that the wax had to be applied and repaired later.
本発明は、上記に鑑み、施工後の白化を抑えることので
きる仕上げ材を提供せんとするものである。In view of the above, the present invention provides a finishing material capable of suppressing whitening after construction.
（課題を解決するための手段） 上記目的を達成するために本発明は、セメント、骨材、
顔料等を配合した仕上げ材基材に若干量の流動パラフィ

する。(Means for Solving the Problems) In order to achieve the above object, the present invention provides a cement, an aggregate,
The finishing material is characterized in that a slight amount of liquid paraffin is uniformly mixed with a finishing material base material containing a pigment or the like.
流動パラフィンは、軽質流動パラフィンがより好まし
く、また仕上げ材基材に対して約１〜10重量％の配合割
合とすることが好ましい。The liquid paraffin is more preferably light liquid paraffin, and the blending ratio is preferably about 1 to 10% by weight with respect to the finishing material substrate.
（作用） 打設したモルタル下地の表面が湿潤な状態の間に、流動
パラフィンを均一的に配合してなる上記モルタル仕上げ

が表面に浮き上がって表面を被覆する。(Function) While the surface of the placed mortar base is wet, when the above mortar finishing material that is uniformly mixed with liquid paraffin is applied and troweled, liquid paraffin with a low specific gravity floats on the surface. To cover.
（実施例） 以下一実施例によって本発明を説明する。(Example) Hereinafter, the present invention will be described with reference to an example.

m2の厚みに均一的に散布し、鏝押さえして養生した。The finishing material base material to which liquid paraffin is mixed may be a mortar-based material that is appropriately mixed, but as an example, cement, aggregate, and pigment mixed at a weight ratio of about 100: 100: 10 are used, and liquid paraffin ( In particular, light liquid paraffin of 37 centistokes or less) was uniformly blended in a weight ratio of 100: 2 to obtain the finishing material of the present invention. After placing this mortar base 8
When the time has passed (it is better after 5 to 10 hours) 2kg / on the substrate
It was sprayed uniformly to a thickness of m 2 , and cured by trowel pressing.

し、モルタル中のアルカリ分（Ca（OH）２等）と空気中

いだためと考えられる。No whitening of the surface was observed 7 days after the construction. This is because the above finishing material is hardened by cement surplus water rising from the base and cement components integrated with the base, strengthening the surface with colored makeup, and at the same time liquid paraffin with a low specific gravity floats on the surface by trowel pressing, It is considered that the primary whitening was prevented by coating and blocking the contact between the alkaline component (Ca (OH) 2 etc.) in the mortar and CO 2 in the air.
この場合、鏝押えすることにより、流動パラフィンが表
面に浮いて水と置換されるので、強度低下を起こさな
い。In this case, since the liquid paraffin floats on the surface and is replaced with water by pressing the trowel, the strength does not decrease.
また、施工後７日経過した仕上げ面の摩耗試験（テーバ
ー式2000rpm）結果では、上記仕上げ材の表面の摩耗減
厚は0.40mmであった。In addition, as a result of the abrasion test (Taber type 2000 rpm) of the finished surface after 7 days from the construction, the wear reduction of the surface of the finished material was 0.40 mm.
一方、流動パラフィンを配合しない上記と同配合の仕上
げ材を上記と同条件で施工したものの摩耗減厚は同試験
の結果0.45mmであった。On the other hand, the wear reduction of the finishing material of the same composition as described above, which did not contain liquid paraffin, was applied under the same conditions as above, and the result of the same test was 0.45 mm.

り、表面強度を向上させたためと考えられる。According to the present invention, the surface strength was clearly improved. This is because liquid paraffin remains on the finished surface, which prevents evaporation of water from the substrate, and by that amount, the surface as well as the substrate is sufficiently water-cured, improving the surface strength. Conceivable.

押え時に上滑りし、表面が緻密に仕上がらない。In the above description, liquid paraffin is a mixture of liquid saturated hydrocarbons having a very high purity which belongs to the lubricating oil fraction in terms of boiling point, but those having a low viscosity have good workability for trowel coating. The compounding amount with respect to the finishing material is 1 to 10%, the optimum value is 2
It is preferably in the range of 4%, and when it is too small, the whitening preventive effect is reduced, and when it is too large, excess liquid paraffin causes upward slip during trowel pressing, and the surface cannot be finished finely.

できる。(Effects of the Invention) As described above, according to the finishing material of the present invention in which liquid paraffin is blended, liquid paraffin having a low specific gravity remains on the finishing surface to block the contact between the alkali component in the cement and the air, Surface whitening of the mortar surface can be suppressed. At the same time, evaporation of water from the substrate is suppressed and water curing is sufficiently performed, so that the surface strength of the finished surface can be improved.

It can work as a lubricant and improve workability.
