作業に好適な大きさである。In Table 1 above, ceramics are porcelain heated to 1200 degrees
The material is sintered at 1350 degrees and then pulverized into particles having a predetermined size. That is, a screen of about 10 mesh size, for example, is placed below the crusher, and the ceramic lumps introduced from above are crushed, and particles of a predetermined diameter are taken out through the lower screen. When using a 0-rotation type crusher, it is possible to have a structure in which crushing is automatically repeated until particles of a predetermined diameter are obtained. In addition, the ceramic particles are 8
A size of ~40 menshi is suitable for spraying work.
セメントは普通ポルトランドを使用した。Ordinary Portland cement was used.

張性セメント混和剤を使用した。An expansible cement admixture was used as an admixture for mixing ceramics and cement.
乾単剤としてのエマルジョンはＰＶＡ （ポリビニルア

接着剤としてのラテックスはＳＢＲ（スチレンブタジェ
ンラバー）を使用した。SBR (styrene butadiene rubber) was used as the latex adhesive.
消泡剤はセメントの表面への泡の発生を防止するもので
、例えばシリコン等を用いた。The antifoaming agent is something that prevents foam from forming on the surface of the cement, and for example, silicone or the like is used.
その他のものとして、例えば微量の安定剤や防腐剤を合
計０．５重量％だけ添加した。As other substances, for example, trace amounts of stabilizers and preservatives were added in a total amount of 0.5% by weight.
前記表１の実施例■では、セラミックス以外の重量％は
好適であるものの、セラミックスの重量％が少ないため
該セラミックスとセメントの混合色ではセメント自体の
色合いの方が強くセラミックス特有の色合いが十分に生
かされないし、セメントの色あせが目立つ。In Example 1 of Table 1 above, although the weight percentage of materials other than ceramics is suitable, the weight percentage of ceramics is small, so in the mixed color of ceramics and cement, the color of the cement itself is stronger and the color unique to ceramics is not sufficient. It doesn't make any use of it, and the color of the cement is noticeable.
一方、実施例■では、全ての成分の重量％が好適であり
、セラミックス自体の色合いも十分に生かされる。また
、セラミックスとセメントとの混和性も良好であるとと
もに、吹き付は後の接着性及び乾燥時間も良好である。On the other hand, in Example 2, the weight percentages of all the components are suitable, and the color of the ceramic itself can be fully utilized. In addition, the compatibility between ceramics and cement is good, and the adhesion and drying time after spraying are also good.
なお、この実施例における、セラミックスとセメントと
の配合割合では、混合色として緑、淡緑、茶、淡茶等が
得られる。これは、セラミックスの焼結温度や磁器の種
類により実現可能となる。Note that with the mixing ratio of ceramics and cement in this example, green, light green, brown, light brown, etc. can be obtained as mixed colors. This can be achieved depending on the sintering temperature of the ceramic and the type of porcelain.
実験では、吹き付は後１年６ケ月経過しても、全く褪色
や剥げが見られなかった。これは色粉の場合に比して著
しく長い。In experiments, no fading or peeling was observed even after 1 year and 6 months after spraying. This is significantly longer than in the case of colored powder.
また、実施例■では、セラミックスとセメントとの混合
配分が太き（異なるため混和性及び強度的な問題を生じ
る。In addition, in Example 2, the mixing ratio of ceramics and cement is large (different), which causes problems in miscibility and strength.
次に、上記成分から成るモルタル材を法面保護緑化工法
に使用する場合について説明する。Next, a case will be described in which a mortar material comprising the above components is used in a slope protection greening method.
法面保護緑化工法は、先ず法面を整形し、この整形され
た法面に、例えば天然繊維等から成りその中に所望の種
子が蒔かれた帯状の発芽助長マットが敷設される。更に
、この発芽助長マット全面を覆うように亀甲金網が張ら
れ、この上から所定間隔毎にアンカービンが打込まれて
固定される。In the slope protection greening method, first the slope is shaped, and a belt-shaped germination promoting mat made of, for example, natural fibers and in which desired seeds are sown is laid on the shaped slope. Further, a hexagonal wire mesh is stretched so as to cover the entire surface of this germination promoting mat, and anchor bottles are driven and fixed at predetermined intervals from above.
この状態で、次に本発明に係るモルタル組成物の吹き付

た種子は吹き付は漏れ部分から法面に向けて発芽し、成
長する。In this state, the mortar composition according to the present invention is then sprayed mainly on the anchor bottle portion. In this way, almost the entire slope surface is covered with the mortar composition. Seeds sown on the germination-promoting mat, which is sufficiently sprayed onto the surface of rocks that appear on the slope, will germinate and grow from the leaking areas toward the slope.
なお、モルタル組成物は、予め所定の混合割合でセラミ

割合で混ぜておき、吹き付は時に両者を混ぜるようにし
て混合作業乃至吹き付は作業効率を向上させた。For the mortar composition, ceramics and cement are mixed in advance at a predetermined mixing ratio, while admixtures, drying agents, adhesives, stabilizers, and preservatives are separately mixed in advance at a predetermined mixing ratio. When spraying, the two are sometimes mixed, and the mixing work or spraying improves work efficiency.
