Description

この発明は、建物、河川、道路、公園、ダム等の土木建造物において、その外面、例えば、建物の外壁面、屋上及び屋根等、擁壁等の法面等、高速道路の防護壁等、河川の護岸等を緑化するのに好適な植生緑化基盤材の製造方法に関する。   This invention is a civil engineering structure such as a building, river, road, park, dam, etc., and its outer surface, for example, the outer wall of the building, the roof, roof, etc. The present invention relates to a method for producing a vegetation greening base material suitable for greening river revetments and the like.

これまで、石炭火力発電所から排出されるフライアッシュやクリンカーアッシュを原料とし、これに水硬性セメントと粘土質原料又はガラス粉とを配合して混合し、平板状等の所定の形状に成形して乾燥し、次いで１０００〜１２００℃で焼成して多孔質焼結体からなる植生緑化基盤材を製造することが提案されている。   Up to now, fly ash and clinker ash discharged from coal-fired power plants are used as raw materials, and hydraulic cement and clayey raw materials or glass powder are blended and mixed to form a flat shape. It is proposed to produce a vegetation planting base material composed of a porous sintered body by firing at 1000 to 1200 ° C. and then drying.

例えば、特許第2,756,934号公報には、石炭灰フライアッシュとクリンカーアッシュとを両者の合計で５０〜８５重量%、木節粘土等の粘土質原料と高炉セメント等の水硬性セメントとを両者の合計で１５〜３０重量%（但し、水硬性セメントは粘土質原料１重量部に対して、０．３〜０．５重量部の範囲の量で調合する）及び高炉水滓スラグ等の焼結調整材料０〜２０重量%からなる原料組成物を成形し、乾燥した後、焼成過程においてCaOを含むアルカリ性水蒸気による水熱反応過程を経て１０００〜１２００℃の温度で焼成することにより、保水性と透水性を有して舗道ブロックや植生基板材として有用な多孔質焼結体を製造する方法が提案されている。   For example, in Japanese Patent No. 2,756,934, coal ash fly ash and clinker ash are combined in a total amount of 50 to 85% by weight. Clay raw materials such as Kibushi clay and hydraulic cements such as blast furnace cement are combined in total. 15-30% by weight (however, hydraulic cement is prepared in an amount in the range of 0.3-0.5 part by weight with respect to 1 part by weight of clay raw material) and sintering adjustment of blast furnace water slag, etc. After forming and drying a raw material composition composed of 0 to 20% by weight of the material, it is fired at a temperature of 1000 to 1200 ° C. through a hydrothermal reaction process using alkaline water vapor containing CaO in the firing process, thereby maintaining water retention and water permeability. A method for producing a porous sintered body having a property and useful as a pavement block or a vegetation substrate material has been proposed.

しかしながら、この方法においては、骨材として粒径０．５mm以下のフライアッシュと粒径０．５〜１mmのクリンカーアッシュとの混合物が用いられているので、保水性や透水性には優れているものの、骨材粒子間に形成される孔隙が小さく、根の細い極めて小型の植物は生育するものの、例えばベンケイソウ科セダム属植物等の比較的大型の植物は生育できないという問題がある。   However, in this method, since a mixture of fly ash having a particle size of 0.5 mm or less and clinker ash having a particle size of 0.5 to 1 mm is used as an aggregate, it is excellent in water retention and water permeability. However, although pores formed between aggregate particles are small and very small plants with thin roots grow, there is a problem that relatively large plants such as the genus Sedum can not grow.

また、特許第3,158,086号公報には、粒度１．５mm〜１０．０mmの範囲にあるクリンカーアッシュ骨材を重量比で４５%〜８０%、ソーダ石灰ガラスと水硬性セメントよりなる多孔質結晶化ガラス成分を重量比で２０%〜５５%からなり、さらに、これらの配合材の配合量に対して成形用水分を重量比で１０%〜２５%の範囲で加えて混合し、造粒した組成物を、２０分〜６０分の養生反応過程を経て振動成形機型枠内に充填し、成形面圧力５kg/cm2〜３０kg/cm2の範囲で平板状、或いはブロック状に成形し、該成形体を養生硬化し乾燥した後に１０００℃〜１２００℃の温度範囲で焼成することにより、保水性と透水性を有して透水・保水材料、ろ過材料、浄化材料、吸音材料、植生用材料等として有用な連続気泡の孔隙を有する粗粒子焼結体を製造する方法が提案されている。 Japanese Patent No. 3,158,086 discloses a porous crystallized glass composed of 45% to 80% by weight of clinker ash aggregate having a particle size in the range of 1.5 mm to 10.0 mm, soda lime glass and hydraulic cement. A composition comprising 20% to 55% by weight of the ingredients, and further mixing and granulating water for molding in a range of 10% to 25% by weight with respect to the amount of these ingredients. and through a curing reaction process 20 to 60 minutes was charged into the vibration molding machine mold within the molding surface pressure of 5kg / cm 2 ~30kg / cm 2 of flat plate in the range, or formed into a block shape, molding After the body is cured and dried, it is fired in the temperature range of 1000 ° C to 1200 ° C, so that it has water retention and water permeability, as a water permeable / water retaining material, filtration material, purification material, sound absorbing material, vegetation material, etc. A method for producing a coarse-grained sintered body having useful open-cell pores A law has been proposed.

しかしながら、この方法においては、骨材粒子間に１００μm（0.1mm）〜５０００μm（5mm）の孔隙を有する粗粒子焼結体が得られるが、この方法の場合においても、上述したベンケイソウ科セダム属植物等の比較的大型の植物は生育し難いという問題がある。   However, in this method, a coarse particle sintered body having pores of 100 μm (0.1 mm) to 5000 μm (5 mm) between the aggregate particles can be obtained. There is a problem that relatively large plants such as are difficult to grow.

更に、特開2002-335,747号公報には、０．１〜１００μmの多数の細孔を有するクリンカーアッシュ等の無機材料を造粒して粒径５〜１５mmの造粒骨材（粗粒骨材）を調製し、この粗粒骨材にソーダ石灰ガラス及び水硬性セメントよりなる多孔質結晶化ガラス（バインダー）を造粒骨材が６０〜９５重量%で多孔質結晶化ガラスが５〜４０重量%となるように配合し、これら配合物１００重量部に対して１０〜２５重量部の成形用水分を添加して混合し、得られた造粒骨材混合物を型枠内に投入し、成形面圧力５kg/cm2以下で振動成形を行い、得られた成形物を養生した後、１０００〜１２００℃で焼成する緑化用植生基盤材の製造方法が提案されている。 Furthermore, JP 2002-335,747 A discloses a granulated aggregate (coarse aggregate) having a particle diameter of 5 to 15 mm by granulating an inorganic material such as clinker ash having a large number of pores of 0.1 to 100 μm. ), And porous crystallized glass (binder) made of soda-lime glass and hydraulic cement is added to this coarse-grained aggregate. The aggregated aggregate is 60 to 95% by weight and the porous crystallized glass is 5 to 40% by weight. %, And 10 to 25 parts by weight of molding water is added to 100 parts by weight of these blends and mixed. The resulting granulated aggregate mixture is put into a mold and molded. A method for producing a vegetation base material for greening is proposed in which vibration molding is performed at a surface pressure of 5 kg / cm 2 or less, the obtained molded product is cured, and then fired at 1000 to 1200 ° C.

しかしながら、この方法においては、骨材粒子間に０．４〜１０mmの孔隙が形成され、ベンケイソウ科セダム属植物等の比較的大型の植物の生育が可能ではあるものの、骨材としてクリンカーアッシュ等の無機材料を造粒して得られた造粒骨材を用いるため、造粒工程が余分に必要になり、それだけ製品コストが嵩むという問題があるほか、機械的強度が不足し、実際の使用に際して機械的強度に優れた細粒部と併用する必要があり、この点でも製品コストが嵩むという問題がある。   However, in this method, a pore of 0.4 to 10 mm is formed between the aggregate particles, and a relatively large plant such as a genus Sedum can be grown, but as an aggregate, clinker ash or the like is used. Since granulated aggregates obtained by granulating inorganic materials are used, an extra granulation step is required, resulting in increased product costs and insufficient mechanical strength. It is necessary to use in combination with a fine-grained portion excellent in mechanical strength, and there is also a problem that the product cost increases in this respect.

特許第2,756,934号公報Japanese Patent No. 2,756,934 特許第3,158,086号公報Japanese Patent No. 3,158,086 特開2002-335,747号公報JP 2002-335,747 A

そこで、本発明者らは、骨材粒子間の孔隙がベンケイソウ科セダム属植物等の比較的大型の植物の生育が可能な程度に十分大きく、また、植生緑化基盤材として用いるのに十分な機械的強度を有し、しかも、造粒工程を必要とせずに工業的に安価に製造することができる植生緑化基盤材の製造方法について鋭意検討した結果、水分含有量５〜２０重量%であって粒径１〜７mmのクリンカーアッシュ、水硬性セメント及びガラス粉からなる原料混合物及び添加水の混合を攪拌羽根無しの拡散混合型ミキサーで行い、得られた混合物を振動成形により成形することにより、微生物の繁殖に適した０．１〜１００μmの多数の細孔を有するクリンカーアッシュの特性を損なうことなく、上記の目的を達成できることを見出し、本発明を完成した。   Therefore, the inventors of the present invention have a sufficiently large pore between the aggregate particles so that a relatively large plant such as a genus Sedum can be grown, and a sufficient machine for use as a vegetation planting base material. As a result of intensive investigations on a method for producing a vegetation planting base material that has high strength and can be produced industrially at low cost without requiring a granulation step, the water content is 5 to 20% by weight. By mixing the raw material mixture consisting of clinker ash having a particle size of 1 to 7 mm, hydraulic cement and glass powder, and added water with a diffusion mixing type mixer without a stirring blade, and molding the resulting mixture by vibration molding, microorganisms The inventors have found that the above object can be achieved without impairing the properties of clinker ash having a large number of pores of 0.1 to 100 μm suitable for the propagation of the present invention, and have completed the present invention.

従って、本発明の目的は、骨材粒子間の孔隙がベンケイソウ科セダム属植物等の比較的大型の植物の生育が可能な程度に十分大きく、また、植生緑化基盤材として用いるのに十分な機械的強度を有する植生緑化基盤材を、造粒工程を必要とすることなく工業的に安価に製造することができる植生緑化基盤材の製造方法を提供することにある。   Accordingly, an object of the present invention is to provide a machine having sufficient pores between aggregate particles so that a relatively large plant such as a genus Sedum can be grown, and sufficient for use as a vegetation planting base material. An object of the present invention is to provide a method for producing a vegetation greening base material, which can industrially produce a vegetation greening base material having sufficient strength industrially at low cost without requiring a granulation step.

すなわち、本発明は、水分含有量５〜２０重量%であって粒径１〜７mmのクリンカーアッシュ４０〜７０重量%、水硬性セメント１５〜２５重量%及び粒径５mm以下のガラス粉１５〜２５重量%からなる原料混合物に添加水を添加してクリンカーアッシュ含有水分を含む水分含有量を１０〜２０重量%に調整し、混合して成形し、乾燥した後、１０００〜１２００℃で焼成して植生緑化基盤材を製造するに際し、原料混合物及び添加水の混合を攪拌羽根無しの拡散混合型ミキサーで行い、得られた混合物を振動成形により成形し、次いで得られた成形物を養生した後、乾燥して焼成する、植生緑化基盤材の製造方法である。   That is, the present invention has a moisture content of 5 to 20% by weight, a clinker ash of 40 to 70% by weight of a particle size of 1 to 7 mm, a hydraulic cement of 15 to 25% by weight, and a glass powder of 15 to 25 of a particle size of 5 mm or less. Add water to the raw material mixture consisting of wt% to adjust the water content including clinker ash containing water to 10 to 20 wt%, mix and mold, dry, then fire at 1000 to 1200 ° C. When producing the vegetation greening base material, mixing of the raw material mixture and added water is performed with a diffusion mixing type mixer without stirring blades, the resulting mixture is molded by vibration molding, and then the resulting molded product is cured, This is a method for producing a vegetation greening base material that is dried and fired.

本発明方法において、原料混合物として用いるクリンカーアッシュは、その保管状況によっても異なるが、通常その水分含有量が５〜２０重量%であり、篩い分けして粒径の大きなものと小さなものとをカットして粒径１〜７mm、好ましくは３〜５mmのものが用いられる。この粒径が１mmより小さいと気孔率が低下し、反対に、７mmより大きくなると機械的強度が低下する。   In the method of the present invention, the clinker ash used as a raw material mixture varies depending on the storage conditions, but usually has a water content of 5 to 20% by weight, and is screened to cut large and small particle sizes. Thus, a particle size of 1 to 7 mm, preferably 3 to 5 mm is used. When the particle size is smaller than 1 mm, the porosity is lowered. On the contrary, when the particle size is larger than 7 mm, the mechanical strength is lowered.

また、このクリンカーアッシュに原料混合物として配合する水硬性セメントについては、例えば高炉セメント、ポルトランドセメント、フライアッシュセメント、アルミナセメント、ホワイトセメント等を挙げることができ、これらはその１種のみを単独で用いることができるほか、２種以上を混合して用いてもよい。この水硬性セメントについては、経済性やリサイクル性等の観点から、好ましくは高炉セメントである。   Examples of the hydraulic cement to be blended in the clinker ash as a raw material mixture include, for example, blast furnace cement, Portland cement, fly ash cement, alumina cement, white cement, etc., and these are used alone. In addition, two or more kinds may be mixed and used. The hydraulic cement is preferably a blast furnace cement from the viewpoints of economy and recyclability.

更に、上記クリンカーアッシュ及び水硬性セメントと共に原料混合物として配合されるガラス粉は、焼成時に溶融し、上記水硬性セメントと相俟って骨材（クリンカーアッシュ）の粒子間に孔隙を形成しつつこれら骨材粒子間を部分的に結合するものであり、具体的には、板ガラス、ビンガラス等の屑ガラス（ソーダ石灰ガラス）を粉砕して形成された５mm以下、好ましくは２mm以下、より好ましくは０．６mm以下のものが用いられる。   Furthermore, the glass powder blended as a raw material mixture together with the clinker ash and hydraulic cement melts at the time of firing, and together with the hydraulic cement forms these pores while forming pores between aggregate (clinker ash) particles. Specifically, the aggregate particles are bonded to each other, and specifically, 5 mm or less, preferably 2 mm or less, more preferably 0, formed by pulverizing waste glass (soda lime glass) such as plate glass and bottle glass. .6mm or less is used.

本発明においては、上記のクリンカーアッシュ、水硬性セメント及びガラス粉をクリンカーアッシュ４０〜７０重量%、好ましくは５５〜６５重量%、水硬性セメント１５〜２５重量%、好ましくは２０重量%前後、及びガラス粉１５〜２５重量%、好ましくは２０重量%前後の割合で配合して原料混合物とする。クリンカーアッシュについてはその配合割合が４０重量%より低いと気孔率が低下して比重が上がり、反対に、７０重量%より高くなると機械的強度が低下し、また、水硬性セメントについてはその配合割合が１５重量%より低いと養生して乾燥したのちの強度が低くて保形性がなく取扱いが困難になり、反対に、２５重量%より高くなると気孔率が低下して比重が上がり、更に、ガラス粉についてはその配合割合が１５重量%より低いと機械的強度が低下し、反対に、２５重量%より高くなると気孔率が低下して比重が上がるという問題が生じる。なお、この原料混合物中には、本発明の趣旨を損なわない範囲で、必要により顔料、フライアッシュ等の第三成分を配合してもよい。   In the present invention, the above clinker ash, hydraulic cement and glass powder are clinker ash 40 to 70% by weight, preferably 55 to 65% by weight, hydraulic cement 15 to 25% by weight, preferably around 20% by weight, and Glass powder is blended at a ratio of 15 to 25% by weight, preferably around 20% by weight to obtain a raw material mixture. For clinker ash, if the blending ratio is lower than 40% by weight, the porosity decreases and the specific gravity increases. On the other hand, if it exceeds 70% by weight, the mechanical strength decreases, and for hydraulic cement, the blending ratio. If it is lower than 15% by weight, the strength after curing and drying is low and the shape is not retained, making it difficult to handle. On the other hand, if it is higher than 25% by weight, the porosity decreases and the specific gravity increases. As for glass powder, if the blending ratio is lower than 15% by weight, the mechanical strength is lowered. On the other hand, if it is higher than 25% by weight, the porosity is lowered and the specific gravity is raised. In addition, in this raw material mixture, you may mix | blend 3rd components, such as a pigment and a fly ash, if necessary in the range which does not impair the meaning of this invention.

このようにして得られた原料混合物については、次に、添加水を添加してクリンカーアッシュ含有水分を含む水分含有量を１０〜２０重量%に調整し、混合して、所定の形状に成形されるが、この際に、原料混合物及び添加水の混合を攪拌羽根無しの拡散混合型ミキサーで行い、また、得られた混合物を振動成形により成形する。   The raw material mixture thus obtained is then molded into a predetermined shape by adding water and adjusting the water content including clinker ash-containing water to 10 to 20% by weight and mixing. At this time, the raw material mixture and the added water are mixed by a diffusion mixing type mixer without a stirring blade, and the obtained mixture is formed by vibration molding.

ここで、原料混合物及び添加水の混合を行うための攪拌羽根無しの拡散混合型ミキサーは、具体的には、搖動盤上に可撓自在のゴムボールを取り付け、このゴムボール内に原料混合物及び添加水を装入し、加速してランダム方向に搖動させながら混合を行うミキサーであり、千代田技研工業株式会社製のOmniMixer（オムニミキサー）がある。   Here, in the diffusion mixing type mixer without stirring blades for mixing the raw material mixture and the added water, specifically, a flexible rubber ball is mounted on a sliding plate, and the raw material mixture and There is an OmniMixer manufactured by Chiyoda Giken Kogyo Co., Ltd., which mixes while charging the additive water and accelerating it in a random direction.

この拡散混合型ミキサーでの原料混合物及び添加水の混合に際しては、好ましくは最初に添加水を添加することなく原料混合物を予備混合し、次いで添加水を添加して混合するのがよく、より好ましくは、添加水を添加することなく行う原料混合物の予備混合を１５０rpm以下、好ましくは８０〜１００のrpmの低速で１０〜６０秒、好ましくは２０〜４０秒行い、また、添加水を添加して行う予備混合後の混合を２００rpm以上、好ましくは２２０〜２４０rpmの高速で３０秒〜５分、好ましくは１〜３分行うのがよい。   When mixing the raw material mixture and the added water in this diffusion mixing type mixer, preferably the raw material mixture is premixed first without adding the added water, and then the added water is added and mixed, more preferably. The premixing of the raw material mixture, which is performed without adding added water, is performed at a low speed of 150 rpm or less, preferably 80 to 100 rpm for 10 to 60 seconds, preferably 20 to 40 seconds, and the added water is added. The mixing after the preliminary mixing is performed at a high speed of 200 rpm or more, preferably 220 to 240 rpm for 30 seconds to 5 minutes, preferably 1 to 3 minutes.

拡散混合型ミキサーで行う原料混合物及び添加水の混合を上記の添加水を添加することなく行う予備混合とこの予備混合の後に添加水を添加して行う混合とに分けて行うことにより、クリンカーアッシュの粒子表面に水硬性セメント及びガラス粉の混合物を均一に付着せしめ、また、このクリンカーアッシュの粒子表面に付着した水硬性セメント及びガラス粉に添加水を均一に行き渡らせることができ、部分的に強度の弱いところが無くて均一な品質の製品を製造することができる。また、その際に、予備混合を１５０rpm以下の低速で行うことにより水硬性セメントやガラス粉の飛散を防止でき、また、添加水を添加して行う予備混合後の混合を２００rpm以上の高速で行うことにより比較的少量の添加水を混合物全体に均一に分散せしめることができるほか、混合時間を短縮することができる。   The clinker ash is obtained by dividing the mixing of the raw material mixture and the additive water performed in the diffusion mixing type mixer into the preliminary mixing performed without adding the above-described additional water and the mixing performed by adding the additional water after the preliminary mixing. The mixture of hydraulic cement and glass powder uniformly adheres to the surface of the particles, and the added water can be evenly distributed to the hydraulic cement and glass powder adhered to the surface of the particles of the clinker ash. A product with uniform quality can be produced with no weakness. At that time, the preliminary mixing is performed at a low speed of 150 rpm or less to prevent scattering of the hydraulic cement or the glass powder, and the mixing after the preliminary mixing performed by adding the added water is performed at a high speed of 200 rpm or more. As a result, a relatively small amount of added water can be uniformly dispersed throughout the mixture, and the mixing time can be shortened.

このようにして得られた原料混合物及び添加水の混合物については、次に振動成形により所定の形状、例えば縦２００〜２５０mm×横２００〜５００mm×厚さ２０〜１００mmの平板形状や、表面に凹凸模様のある平板形状等の種々の形状に成形する。この混合物の振動成形は、通常、振動数２０００〜６０００rpm及び振幅０．２〜１．２mm、好ましくは振動数３０００〜５０００rpm及び振幅０．３〜０．７mmの条件下に、０．０１〜０．２kg/cm2、好ましくは０．０２〜０．０５kg/cm2の面圧を付与しながら行われる。成形条件については振動数・振幅が高すぎるとクリンカーアッシュが破損あるいは破壊する虞があり、反対に、振動数・振幅が低すぎると締め固まらない場合があり、また、振動成形時に加える面圧については０．０１kg/cm2より低いと形状の形成や保持ができなくなり、反対に、０．２kg/cm2より高いとクリンカーアッシュが破損あるいは破壊が発生する。 The raw material mixture and additive water mixture thus obtained are then subjected to vibration molding to a predetermined shape, for example, a flat plate shape having a length of 200 to 250 mm × width of 200 to 500 mm × thickness of 20 to 100 mm, and unevenness on the surface. Molded into various shapes such as a flat plate with a pattern. The vibration molding of this mixture is usually 0.01 to 0 under the conditions of a frequency of 2000 to 6000 rpm and an amplitude of 0.2 to 1.2 mm, preferably a frequency of 3000 to 5000 rpm and an amplitude of 0.3 to 0.7 mm. It is carried out while applying a surface pressure of 2 kg / cm 2 , preferably 0.02 to 0.05 kg / cm 2 . As for molding conditions, if the frequency and amplitude are too high, the clinker ash may be damaged or destroyed. Conversely, if the frequency and amplitude are too low, the clinker ash may not be compacted. If it is lower than 0.01 kg / cm 2 , the shape cannot be formed or held. Conversely, if it is higher than 0.2 kg / cm 2 , the clinker ash is broken or broken.

次に、混合物を成形して得られた成形物については水硬性セメントの水和反応が進んで硬化するまで養生するが、この際の成形物の養生は、好ましくは成形物の曲げ強度が８kg/cm2以上、より好ましくは１０kg/cm2程度になるまで行うのがよく、養生後の成形物の曲げ強度が８kg/cm2より低いと焼成時に破損し易くてその取扱いが困難になる。 Next, the molded product obtained by molding the mixture is cured until the hydration reaction of the hydraulic cement proceeds and hardens. In this case, the molded product preferably has a bending strength of 8 kg. / cm 2 or more, more preferably about 10 kg / cm 2 , and if the molded product has a bending strength of less than 8 kg / cm 2 after curing, it is easily damaged during firing and is difficult to handle.

この成形物の養生は、混合物の成形後、当該成形物を１〜４日間、好ましくは１〜２日間放置する自然養生であっても、また、３０〜８０℃、好ましくは５０℃前後で３〜４時間、好ましくは３〜４時間行う蒸気養生であってもよく、更には、これら自然養生と蒸気養生とを組み合わせて行ってもよい。   Curing of the molded product may be natural curing in which the molded product is allowed to stand for 1 to 4 days, preferably 1 to 2 days after molding of the mixture, and may be 3 to 30 to 80 ° C, preferably about 50 ° C. Steam curing may be performed for ˜4 hours, preferably 3 to 4 hours, or may be performed by combining these natural curing and steam curing.

上記の養生が終了して所定の曲げ強度に達した成形物は、次に焼成され、製品の植生緑化基盤材とされる。この成形物の焼成は、焼成温度１０００〜１２００℃、好ましくは１１００〜１２００℃、及び、焼成時間１．５〜３０時間、好ましくは２〜４時間の条件で行われ、また、焼成装置については、上記焼成条件の焼成温度１０００〜１２００℃及び焼成時間１．５〜３０時間を満たすことができる装置であればどのような装置であつてもよく、例えばシャトルキルン等の装置を用いて行うバッチ式であつても、また、例えばローラーハースキルンを用いて行う連続式であつてもよい。焼成温度が１０００℃より低いと未焼結部分が生じて基盤材の強度が低下し、また、１２００℃より高いと成形物全体が溶融して製品形状を維持できなくなる。   The molded product that has reached the predetermined bending strength after the above curing is fired and used as a vegetation greening base material of the product. Firing of this molded product is performed under the conditions of a firing temperature of 1000 to 1200 ° C, preferably 1100 to 1200 ° C, and a firing time of 1.5 to 30 hours, preferably 2 to 4 hours. Any apparatus can be used as long as the apparatus can satisfy a baking temperature of 1000 to 1200 ° C. and a baking time of 1.5 to 30 hours under the above-described baking conditions, for example, a batch performed using an apparatus such as a shuttle kiln. Even if it is a type | formula, it may be a continuous type | formula performed, for example using a roller hearth kiln. When the firing temperature is lower than 1000 ° C., unsintered portions are formed, and the strength of the base material is lowered.

本発明の方法によって得られる植生緑化基盤材は、通常、嵩比重１．０〜１．２、曲げ強度（JIS A 5411準拠、気乾状態）１N/mm2前後、吸水率（JIS A 5209準拠、体積換算）２０〜３０vol%、及び透水性（インターロッキングブロック協会法）０．３×１０-2〜１０cm/Sを有し、ベンケイソウ科セダム属植物等の比較的大型の植物が十分に生育可能である。 The vegetation planting base material obtained by the method of the present invention usually has a bulk specific gravity of 1.0 to 1.2, bending strength (JIS A 5411 compliant, air-dried) around 1 N / mm 2 , water absorption (JIS A 5209 compliant). , Volume conversion) 20-30 vol%, and water permeability (interlocking block association method) 0.3 × 10 −2 to 10 cm / S, and relatively large plants such as crassulaceae sedum genus grow sufficiently Is possible.

本発明の製造方法によれば、骨材粒子間の孔隙がベンケイソウ科セダム属植物等の比較的大型の植物の生育が可能な程度に十分大きく、また、植生緑化基盤材として用いるのに十分な機械的強度を有する植生緑化基盤材を、造粒工程を必要とすることなく工業的に安価に製造することができる。   According to the production method of the present invention, the pores between the aggregate particles are large enough to allow growth of relatively large plants such as the genus Sedum, and are sufficient for use as a vegetation planting base material. A vegetation greening base material having mechanical strength can be produced industrially at low cost without requiring a granulation step.
