本発明は炭素繊維補強モルタルの製造法および炭素繊維
補強モルタルを使用した建築土木構造物のモルタル塗装
材に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for producing carbon fiber-reinforced mortar and a mortar coating material for architectural and civil engineering structures using carbon fiber-reinforced mortar.
（従来の技術）
従来の繊維補強モルタルの製造法は繊維を直接にセメン
トに混合する方法であるが、繊維の分散性が悪い欠点が
あった。さらに、繊維をシリカを主成分とした混和材、
例えばシリカヒユームを使用してセメントに混合する方
法があるが、塗装した場合にグレーに着色し、白色に仕
上らない欠点がある。(Prior Art) The conventional method for manufacturing fiber-reinforced mortar is to mix fibers directly into cement, but this method has the drawback of poor fiber dispersibility. In addition, fibers can be mixed with silica-based admixtures,
For example, there is a method of using silica fume and mixing it with cement, but it has the disadvantage that when painted, it is colored gray and the finish is not white.
（発明が解決しようとする課題）
本発明者は、塗装した場合に炭素繊維の分散性が良く、
かつ白色に仕上る炭素繊維補強乾燥モルタルについて研
究し、本発明に到達した。(Problems to be Solved by the Invention) The present inventor has discovered that carbon fibers have good dispersibility when painted;
The present invention was achieved through research on carbon fiber-reinforced dry mortar that has a white finish.
（課題を解決するための手段）
本発明は短繊維の炭素繊維１〜５重量％、カルシウム酸
化物５０〜７０重量％および分散剤として炭酸水又は界
面活性剤の０．０１〜１重量％濃度の水溶液３０〜４５
重量％を混練した後乾燥してなる乾燥スラリー２５〜５
０重量％および白セメント５０〜７５重量％を混合する
ことを特徴とする炭素繊維補強乾燥モルタルの製造法で
ある。(Means for Solving the Problems) The present invention has a concentration of 1 to 5% by weight of short carbon fibers, 50 to 70% by weight of calcium oxide, and 0.01 to 1% by weight of carbonated water or a surfactant as a dispersant. Aqueous solution of 30-45
Dry slurry obtained by kneading and drying 25 to 5% by weight
This is a method for producing carbon fiber reinforced dry mortar characterized by mixing 0% by weight and 50 to 75% by weight of white cement.
また、本発明の製造法で製造した炭素繊維補強乾燥モル
タルから成り、炭素繊維の分散が良く、かつ白色に仕上
る建築土木構造物のモルタル塗装材である。It is also a mortar coating material for architectural and civil engineering structures, which is made of carbon fiber-reinforced dry mortar produced by the production method of the present invention, has good dispersion of carbon fibers, and has a white finish.
本発明に使用する炭素繊維は、ピッチ系炭素繊維で短繊
維のものであれば、何でも使用できる。The carbon fiber used in the present invention can be any pitch-based carbon fiber as long as it is short fiber.
カルシウム酸化物としてはＣａＯ１Ｃａｂ、またはＣａ
Ｏｓが使用できるが、好ましいのはＣａＯ３である。Calcium oxide is CaO1Cab or Ca
Although Os can be used, CaO3 is preferred.
スラリー中、カルシウム酸化物が５０重量％より少い場
合は炭素繊維の分散性が悪くなる。カルシウム酸化物が
７０重量％を超えると仕上げたモルタル表面に粉を生じ
、またモルタルがもろくなる。If the calcium oxide content in the slurry is less than 50% by weight, the dispersibility of carbon fibers will be poor. If the calcium oxide content exceeds 70% by weight, powder will form on the surface of the finished mortar, and the mortar will become brittle.
分散剤としては炭酸水または界面活性剤のいずれでもよ
いが、炭酸水のほうが、モルタル塗装材中に気泡が残ら
ず好ましい、界面活性剤としては通常のカチオン系界面
活性剤、アニオン系界面活性荊あるいは非イオン界面活
性剤のいずれでもよい。スラリー中、分散剤が３０重量
％より少いと混合が不充分になり易く、分散剤が４５重
量％より多いと乾燥に時間を要し、熱損失が大きい。The dispersant may be carbonated water or a surfactant, but carbonated water is preferable because it does not leave bubbles in the mortar coating material.As the surfactant, ordinary cationic surfactants and anionic surfactants can be used. Alternatively, any nonionic surfactant may be used. If the amount of dispersant in the slurry is less than 30% by weight, mixing tends to be insufficient, and if the amount of dispersant is more than 45% by weight, drying takes time and heat loss is large.
白セメントは市販の通常の白セメントを使用することが
できる。Commercially available normal white cement can be used as the white cement.
