Description

本発明は、圧縮強度及び引張強度をセメントコンクリート製品の１．５倍程度以上に確保することが可能な高強度樹脂ペースト、高強度樹脂固結物およびそれを用いた路面の施工法に関するものである。   The present invention relates to a high-strength resin paste capable of securing a compressive strength and a tensile strength of about 1.5 times or more of cement concrete products, a high-strength resin consolidated product, and a road surface construction method using the same. is there.

一般に樹脂コンクリートは、骨材と樹脂を混合して製造するが、混合した物が一定の強度に達する事を目的に、樹脂に繊維等を混ぜたり、施工難度を下げる為に、樹脂の粘度を下げたりして、いずれも安定した組成物の製造が難しい。   In general, resin concrete is manufactured by mixing aggregate and resin. For the purpose of achieving a certain level of strength, the mixed resin is mixed with fibers and the viscosity of the resin is reduced to reduce the construction difficulty. In both cases, it is difficult to produce a stable composition.

樹脂コンクリートでは、樹脂に繊維を混ぜる事により、粘度の低い樹脂の液だれを防ぎ強度の向上を計るが、高度な技術、混合するための時間、工程の複雑さ、難度等をもってしてもコンクリートと同程度か、やや上しか期待できない。   In resin concrete, mixing fibers with resin prevents dripping of low-viscosity resin and improves strength, but even with advanced technology, mixing time, process complexity, difficulty, etc. It can be expected to be similar to or slightly above.

その理由は、樹脂量が多くなると、表面に樹脂の厚い皮膜が発生し、骨材と骨材の間に樹脂が飽和状に入り込み、曲げ強度、引張り強度は増加するが、耐摩耗性、圧縮強度が低下する原因になるからである。   The reason for this is that as the amount of resin increases, a thick film of resin is generated on the surface, and the resin enters a saturated state between the aggregates and the bending strength and tensile strength increase, but wear resistance, compression This is because the strength decreases.

これに対して、圧縮強度及び引張強度をセメントコンクリート製品の１．５倍程度以上に確保することが可能な高強度樹脂モルタル、高強度樹脂固結体およびそれを使用した構築物、高強度樹脂固結物二次製品として本件出願人は発明者として下記特許文献の発明をおこなった。
特許第３９３０８９５号公報 In contrast, a high-strength resin mortar capable of securing a compressive strength and a tensile strength of about 1.5 times or more of cement concrete products, a high-strength resin consolidated body, a structure using the same, and a high-strength resin solid The present applicant invented the following patent document as an inventor as a secondary product of a product.
Japanese Patent No. 3930895

この特許文献１は、従来の高強度樹脂コンクリートの製造において、加える鉱物質粉体の量により、高強度樹脂コンクリートの圧縮強度・引張り強度などにバラつきが多く見られて一定した製品が期待できなかったものを改善したもので、エポキシ樹脂、アクリル樹脂、ウレタン樹脂、ポリエステル樹脂、フェノール樹脂から選択される二液性樹脂に、容積比で、樹脂１に対して、粘土鉱物、石粉、或いは人工のポルトランドセメント、フライアッシュ、石膏から選択される樹脂の吸収量が少ない粒径０．１５mm以下の鉱物質粉体を０．５〜１．５の割合で混合し、さらに、フェロニッケルスラグ、銅スラグ、鉄鋼スラグから選択される細骨材及び硬化剤を加えて混合したことを特徴とする。   According to Patent Document 1, in the production of conventional high-strength resin concrete, depending on the amount of mineral powder added, there are many variations in compressive strength, tensile strength, etc. of high-strength resin concrete, and a constant product cannot be expected. A two-component resin selected from an epoxy resin, an acrylic resin, a urethane resin, a polyester resin, and a phenol resin, and a volume ratio of clay mineral, stone powder, or artificial A mineral powder with a particle size of 0.15 mm or less with a low absorption of resin selected from Portland cement, fly ash, and gypsum is mixed in a ratio of 0.5 to 1.5, and ferronickel slag and copper slag A fine aggregate selected from steel slag and a hardener are added and mixed.

前記特許文献１でも、組成物の強度不均一などによりコンクリートと同程度の強度しか期待が出来なかったりするおそれがあり、鉱物質の粉体の混合割合に難度があり、安定した組成物の製造には作業錬度と工程が増え、コンクリートより優れた強度、耐摩耗性が期待できず製造コストも高い為に実用化が難しい。   Even in the above-mentioned Patent Document 1, there is a risk that only the same strength as that of concrete can be expected due to non-uniform strength of the composition, etc., and there is a difficulty in the mixing ratio of mineral powder, and the production of a stable composition However, it is difficult to put to practical use because of the increased work refining and process, strength and wear resistance superior to concrete and high manufacturing costs.

特許文献１の場合、樹脂に鉱物質粉体を加えて混合するが、鉱物質粉体は樹脂に対しての割合が、容積比、樹脂１に対して０．５〜１．５では圧縮強度、引張り強度、曲げ強度のそれぞれの強度がバランス良い組成物を製造する事が難しい。   In the case of Patent Document 1, the mineral powder is added to the resin and mixed, but the mineral powder has a compressive strength at a volume ratio of 0.5 to 1.5 relative to the resin. It is difficult to produce a composition having a good balance between tensile strength and bending strength.

また、従来の路面補修では、舗装全体を撤去し新規構築するか、短期に磨耗する事を承知しながら、アスファルト等でオーバーレイ施工を行っていた。   In addition, in conventional road surface repairs, the entire pavement was removed and newly constructed, or overlay work was performed with asphalt or the like while being aware that it would wear out in the short term.

特に、従来の路面補修では既設道路との接合点「すりつけ」の箇所を、カッターで切断して一部を削り取り、施工後に平坦な形になる様な工程が必要であった。   In particular, in the conventional road surface repair, a process of cutting a part of the joint “rubbing” with the existing road with a cutter to remove a part and forming a flat shape after construction is necessary.

本発明の目的は前記従来例の不都合を解消し、高強度樹脂ペースト、高強度樹脂固結物としては、圧縮強度、引張り強度はコンクリートの製品の２〜３倍強、製品の耐磨耗性としてラベリング係数０．１以下の耐磨耗性を持つもので、しかも、固結物の密度、強度、組成が安定してバランス良い組成物を得ることができ、また、これを路面の補修施工に用いた場合に、カッターで切断して一部を削り取り、施工後に平坦な形になる様な工程を必要とせずに、施工工程数を減らしコストを下げ、時間の短縮が出来る高強度樹脂ペースト、高強度樹脂固結物およびそれを用いた路面の施工法を提供することにある。   The object of the present invention is to eliminate the inconveniences of the above-mentioned conventional examples, and as a high-strength resin paste and high-strength resin consolidated product, the compressive strength and tensile strength are 2-3 times that of a concrete product, and the wear resistance of the product. It has a wear resistance with a labeling coefficient of 0.1 or less, and it is possible to obtain a well-balanced composition in which the density, strength, and composition of the consolidated product are stable. A high-strength resin paste that reduces the number of construction steps, reduces costs, and shortens the time without using a process that cuts with a cutter and removes part of the workpiece to make a flat shape after construction. Another object of the present invention is to provide a high-strength resin consolidated product and a road surface construction method using the same.

請求項１記載の本発明は前記の目的を達成するため、高強度樹脂ペーストとしては、エポキシ樹脂、アクリル樹脂、ウレタン樹脂、ポリエステル樹脂、フェノール樹脂から選択される二液性樹脂に容積比で樹脂１に対して、人工のポルトランドセメント、フライアッシュ、粒径０．１mm以下のフェロニッケルスラグから選択される鉱物質粉体を０．３以下の割合で混合い更にフェロニッケルスラグの細骨材および硬化剤を加えて混合したことを要旨とするものである。 In order to achieve the above object, the high-strength resin paste according to the first aspect of the present invention is a resin having a volume ratio of a two-component resin selected from an epoxy resin, an acrylic resin, a urethane resin, a polyester resin, and a phenol resin. for one, artificial Portland cement, fine aggregate of fly ash, further ferronickel slag had mixed mineral powder selected from particle size 0.1mm following ferronickel slag in a ratio of 0.3 or less and The gist is that a curing agent is added and mixed.

It is characterized in that it penetrates, increases the density, and eliminates the brittleness of the conventional resin consolidated product to increase the strength.

It can be used as a filling material in order to restore the road bearing capacity where the surface has been deeply worn away due to spilling.

請求項３記載の本発明によれば、装軌車、重量大型車輌による損傷、磨耗した道路を再構築する場合に掘削、カッターで切断して一部を削り取り、施工後に平坦な形になる様な工程を必要とせずにすみ、撤去の工程が省かれ、施工によるコンクリート塊などの産業廃棄物が排出されないですむ。   According to the third aspect of the present invention, when reconstructing a road that has been damaged or worn by a tracked vehicle or a heavy vehicle, excavation, cutting with a cutter, scraping a part, and forming a flat shape after construction This eliminates the need for an additional process, eliminates the removal process, and eliminates industrial waste such as concrete lumps.

In addition, the density, strength and composition of the consolidated product are stable and well balanced. A composition can be obtained.

また、高強度樹脂ペースト、高強度樹脂固結物を用いた路面の施工法としては、路面の補修施工として、カッターで切断して一部を削り取り、施工後に平坦な形になる様な工程を必要とせずに、施工工程数を減らしコストを下げ、時間の短縮が出来る。   Also, as a road surface construction method using high-strength resin paste and high-strength resin solidified material, as a road surface repair construction, a process that cuts with a cutter and scrapes off a part and forms a flat shape after construction. Without the need, the number of construction processes can be reduced, the cost can be reduced, and the time can be shortened.

装軌車、重量大型車輌による損傷、磨耗した道路を再構築する場合に掘削、撤去の工程が省かれ施工によるコンクリート塊などの産業廃棄物が排出されない。   When rebuilding a damaged or worn road due to a tracked vehicle or a heavy heavy vehicle, excavation and removal processes are omitted, and industrial waste such as concrete blocks due to construction is not discharged.

本発明の高強度樹脂ペーストは、エポキシ樹脂、アクリル樹脂、ウレタン樹脂、ポリエステル樹脂、フェノール樹脂から選択される二液性樹脂に、容積比で、樹脂１に対して、人工のポルトランドセメント、フライアッシュ、粒径０．１mm以下のフェロニッケルスラグから選択される、鉱物質粉体を０．３以下の割合で混合し、更に粒径５mm以下のフェロニッケルスラグの細骨材および硬化剤を加えて形成した。 The high-strength resin paste of the present invention is a two-component resin selected from an epoxy resin, an acrylic resin, a urethane resin, a polyester resin, and a phenol resin. The mineral powder selected from ferronickel slag having a particle size of 0.1 mm or less is mixed at a ratio of 0.3 or less, and further, a fine aggregate of ferronickel slag having a particle size of 5 mm or less and a hardener are added. Formed.

本発明で使用される二液性樹脂は、エポキシ樹脂、アクリル樹脂、ウレタン樹脂、ポリエステル樹脂、フェノール樹脂等であり、硬化剤としてはアミン系硬化剤を挙げることが出来る。   The two-component resin used in the present invention is an epoxy resin, an acrylic resin, a urethane resin, a polyester resin, a phenol resin, or the like, and examples of the curing agent include amine-based curing agents.

本発明は高強度樹脂ペーストを製造する場合に、骨材と鉱物質粉体を同時に混合攪拌した後に、二液性樹脂の主剤を混ぜて充分に混合し、さらに硬化剤を加えて混合する。   In the present invention, when producing a high-strength resin paste, the aggregate and the mineral powder are mixed and stirred at the same time, and then the main component of the two-component resin is mixed and mixed thoroughly, and further a curing agent is added and mixed.

本発明は、鉱物質粉体を加えることにより、樹脂に鉱物質粉体が絡み、鉱物質粉体を含んだ樹脂が骨材と骨材の隙間に浸透し、密度を高めて、従来の樹脂固結物の脆さを排除して強度を高めることを特徴とするものである。   By adding mineral powder, the present invention entangles the mineral powder with the resin, the resin containing the mineral powder penetrates into the gap between the aggregate and the aggregate, and increases the density. It is characterized by increasing the strength by eliminating the brittleness of the consolidated product.

樹脂量を容積比で１とした時、鉱物質粉体を０．３以下の割合で混合する事により固結物の密度、強度、組成が安定して出来上がり、粉体量が増えると極端にも脆くなる事が試験練り、実験施工の結果証明されている。   When the resin amount is 1 by volume, the density, strength, and composition of the solidified material are stably produced by mixing the mineral powder at a ratio of 0.3 or less. It has been proved as a result of experimental construction that it becomes brittle.

鉱物質粉体とは、人工のポルトランドセメント、フライアッシュ、粒径０．１mm以下のフェロニッケルスラグを言う。   Mineral powder refers to artificial Portland cement, fly ash, and ferronickel slag having a particle size of 0.1 mm or less.

樹脂１に対し３程度の割合で細骨材を混合し、高強度樹脂ペーストを製造する。   Fine aggregate is mixed at a ratio of about 3 with respect to resin 1 to produce a high-strength resin paste.

高強度ペーストは、混合ミキサーに、細骨材と鉱物質粉体を投入、混合して樹脂の主剤を投入均一な状態まで混合してから硬化剤を加えて混合し製造する。高強度樹脂ペーストに用いる細骨材は、硬度の大きな材料の粒径５mm以下のフェロニッケルスラグを使用する事により安定した高強度の製品が得られる。   The high-strength paste is manufactured by adding and mixing fine aggregate and mineral powder into a mixing mixer, mixing the resin main agent to a uniform state, adding a curing agent, and mixing. The fine aggregate used in the high-strength resin paste can obtain a stable and high-strength product by using a ferronickel slag having a particle size of 5 mm or less, which is a material with high hardness.

本発明で使用される、鉱物質粉体、細骨材、粗骨材はいずれも水分を含んでいない事が前提である。   It is assumed that the mineral powder, fine aggregate, and coarse aggregate used in the present invention do not contain moisture.

本発明で使用される鉱物質粉体、細骨材、粗骨材は、安価で大量に供給される材料を主原料としているが、結合剤の二液性樹脂のエポキシ樹脂、アクリル樹脂、ウレタン樹脂他の樹脂も、原油の輸入価格により高価格に変動し易く、従来品で使用していた樹脂量を約１／２程度に削減し、製造コストの低減化を果した。   Mineral powders, fine aggregates and coarse aggregates used in the present invention are mainly made of materials that are inexpensive and supplied in large quantities, but binders are two-part resins such as epoxy resins, acrylic resins, urethanes. Resins and other resins are also likely to fluctuate to high prices due to the import price of crude oil, reducing the amount of resin used in conventional products by about 1/2, and reducing manufacturing costs.

使用する鉱物質粉体、細骨材は乾燥していることが前提であるが、樹脂は其の儘混合できるので特殊なミキサーを必要としない。   The mineral powder and fine aggregate to be used are premised on being dry, but the resin can be mixed, so no special mixer is required.

本発明の高強度樹脂ペーストは、耐磨耗性に優れていて、コンクリート製品のラベリング係数が０．７８／cm２程度に比べ、０．０２／cm２程度まで向上し、磨耗率が１０倍以上もあることが試験結果からわかる。 The high-strength resin paste of the present invention has excellent wear resistance, and the labeling coefficient of concrete products is improved to about 0.02 / cm 2 compared to about 0.78 / cm 2 , and the wear rate is 10 times. It can be seen from the test results that there are also the above.

本発明の高強度樹脂固結物は、前記高強度樹脂ペーストに、粗骨材として砕石〔６〜７号砕石〕を１：１程度の割合で、加えてミキサーで混合する事により得る。   The high-strength resin consolidated product of the present invention is obtained by adding crushed stone [6-7 crushed stone] as a coarse aggregate to the high-strength resin paste in a ratio of about 1: 1 and mixing with a mixer.

本発明の高強度樹脂固結物は、圧縮強度でコンクリートの２倍以上、最大３倍強、曲げ強度は３〜４倍を、ラベリング係数は０．２０／cm２の材料試験結果が出ている。 The high-strength resin solidified material of the present invention has a compressive strength of more than twice that of concrete, a maximum of slightly more than 3 times, a bending strength of 3 to 4 times, and a material test result of a labeling coefficient of 0.20 / cm 2. Yes.

It can be used as a filling material in order to restore the road bearing capacity when the surface is deeply polished. Furthermore, a surface layer is constructed with a high-strength resin paste on top of it to serve as a wear-resistant road.

The construction site does not change at all due to the load caused by the crawler track on the uphill road or the load caused by turning. Condensed concrete roads constructed at the same time generated dust due to surface wear caused by crawler tracks.

本発明は、特殊道路、重量交通あるいは大容量交通にさらされる、耐磨耗性、耐久性などを要求される道路の補修または構築材料として最適である。特に、路盤等の崩壊した道路の機能回復を急ぐ場合の改修材料、交通量が多く道路の改修が困難な道路の改修材料として有効である。   The present invention is most suitable as a material for repairing or constructing roads that are exposed to special roads, heavy traffic or large-capacity traffic and require abrasion resistance, durability and the like. In particular, it is effective as a renovation material for urgent recovery of the function of roads such as roadbeds, and as a renovation material for roads that have a high traffic volume and are difficult to repair.

また、引張り力が作用する部分での鉄筋等による補強を施さない構造材料としても使用できる。   It can also be used as a structural material that is not reinforced by reinforcing bars or the like at the portion where the tensile force acts.

本発明により従来コンクリート構造において、引張り力が作用する部材に必要不可欠であった鉄筋等の補強材の必要が無くなった。叉工起用どじ油脂固結物の性能を生かし道路の舗装が装軌車等の走行により損耗や、磨耗した場合に、従来は舗装全体を撤去し、新規構築するか、短期に磨耗する事を承知しながら、アスファルト等でオーバーレイ施工を行っていたが、磨耗した部分に本発明の材料で４cm程度のオーバーレイを行う事で強靭な舗装としての機能回復が短時間で可能になる。   According to the present invention, in the conventional concrete structure, there is no need for a reinforcing material such as a reinforcing bar, which is indispensable for a member to which a tensile force acts. If the road pavement is worn or worn by running a tracked vehicle, etc., taking advantage of the performance of the forged oil and fat solidified material, it is necessary to remove the entire pavement and build a new one or wear it in the short term. Although it was recognized that overlay construction was performed with asphalt or the like, the function recovery as a strong pavement can be achieved in a short time by overlaying about 4 cm on the worn portion with the material of the present invention.
