Description
本発明は火力発電所から排出される石炭灰の廃材（クリンカアッシュ）を主成分として含むコンクリート型枠材（ツネ・コンパネコンクリート型枠材）の製造方法に関する。 TECHNICAL FIELD The present invention relates to a method for producing a concrete form material (tunnel / concrete concrete form material) containing a waste material (clinker ash) of coal ash discharged from a thermal power plant as a main component.
火力発電所から排出される石炭灰の廃材クリンカアッシュは高温で燃焼された安全・安心な原料であって、通常の粗骨材よりも比重が軽く、これを原料としたツネ・コンパネ型枠材は特に経済性、耐久性、作業性、作業環境、工期短縮、等に優れたコンクリート型枠材とされている。 Clinker ash, a waste material from coal ash discharged from thermal power plants, is a safe and reliable raw material burned at a high temperature, and has a lighter specific gravity than ordinary coarse aggregates. Is considered to be a concrete formwork material particularly excellent in economy, durability, workability, work environment, shortening of construction period, and the like.
しかし、クリンカアッシュは連続気泡の素材のため、熱が伝わりやすく、これを原料として使うためには独立気泡に変換する必要がある。 However, since clinker ash is an open-celled material, heat is easily transmitted, and in order to use it as a raw material, it is necessary to convert it into closed cells.
さらに、クリンカアッシュは国土交通大臣認定防耐火性能試験に合格しなければ製品として使用出来ない。このため性能試験に合格するためにクリンカアッシュを連続気泡から独立気泡の素材に変換する必要がある。 In addition, clinker ash cannot be used as a product unless it passes the fire and fire resistance test approved by the Minister of Land, Infrastructure, Transport and Tourism. Therefore, in order to pass the performance test, it is necessary to convert the clinker ash from an open cell to a closed cell material.
この種の型枠材として、従来、ベニヤ板を用いた型枠材（ベニヤコンパネ板型枠材）が用いられていた。しかし、ベニヤコンパネ板を製造するために地球上の森林を伐採することは生態系と地球環境を害し、人間社会に悪影響を与える。さらに、森林を破壊することは地球温暖化を促進させることにもつながる。 Conventionally, a mold material using a plywood plate (a veneer panel plate mold material) has been used as this type of mold material. However, cutting down the earth's forests to produce veneer control panels harms the ecosystem and the global environment and adversely affects human society. In addition, destroying forests also promotes global warming.

The present invention provides a method for producing a concrete form material with improved defects.
前述の課題を解決するため、本発明のコンクリート型枠材によれば、火力発電所から排出される石炭灰（クリンカアッシュ）を主成分原料とし、これにセメントを含む添加物を添加混合し、得られる混合物を蒸気養生して所望の大きさの型枠規格に成型することを特徴とする。 In order to solve the above-described problems, according to the concrete formwork material of the present invention, coal ash discharged from a thermal power plant (clinker ash) is used as a main component raw material, and an additive containing cement is added and mixed thereto. The resulting mixture is steam-cured and molded into a mold standard having a desired size.
上述の本発明型枠材は原材料として火力発電所から排出される石炭灰の廃材（クリンカアッシュ）を主成分とした原材料をコンクリート型枠材（ツネ・コンパネ型枠材）として用いたから、地球上の森林を伐採する必要がなく、したがって、生態系と地球環境を破壊することがなく、さらに地球温暖化を防止する。 The above-mentioned formwork material of the present invention uses a raw material mainly composed of waste coal ash (clinker ash) discharged from a thermal power plant as a raw material as a concrete formwork (tsune / compane formwork). There is no need to cut down forests, thus destroying ecosystems and the global environment, and further preventing global warming.

Clinker ash, which is a waste material of coal ash, has a low specific gravity and is easy to transfer heat because it is an open cell material.
本発明は上述のクリンカアッシュにセメントを含む添加物を添加混合する。この混合は例えばコンパネ板の寸法規格、幅９１０ｍｍ×長さ１９２０ｍｍ×厚さ１６ｍｍ、型枠四方の底部分に三角リーブ加工した型枠中で行われる。 In the present invention, an additive containing cement is added to and mixed with the above clinker ash. This mixing is performed, for example, in a form plate having a dimensional standard of a panel board, width 910 mm × length 1920 mm × thickness 16 mm, and a triangular reve process on the bottom of the form frame.
上述添加物として例えば普通セメント、アリナミンセメントの他に珪藻土、黒曜石、石こう、水酸化アルミナ、強化ガラスチョップ（長さ１３ｍｍ）、保水剤等が挙げられる。 Examples of the additives include diatomaceous earth, obsidian, gypsum, alumina hydroxide, tempered glass chop (length 13 mm), water retention agent and the like in addition to ordinary cement and arinamin cement.
さらに、本発明は得られる混合物を蒸気養生して硬化する。この場合、上記温度は約６０℃、養生時間は約２４時間である。その後、天日乾燥を１４日間行い、圧縮強度２４０度を確認して本発明にかかる型枠材（ツネ・コンパネ板）を得る。 Furthermore, the present invention cures the resulting mixture by steam curing. In this case, the temperature is about 60 ° C. and the curing time is about 24 hours. Then, sun drying is performed for 14 days, and the compressive strength of 240 degrees is confirmed to obtain the mold material (tsune / panel board) according to the present invention.
