Description

本発明は、コンクリートや木材等からなる建物外壁や建物基礎等に塗工して補強する二液性建造物補強剤組成物に用いる硬化剤に関するものである。 The present invention relates to hardening agents that used in two-part building reinforcing composition to reinforce by coating a concrete or made of wood such as buildings exterior walls and buildings foundation like.

ビルや戸建住宅の外壁、基礎部分、柱部分等のコンクリートや木材からなる部分の劣化や腐食に対する防護策として、セメントに樹脂分を混入した材料を被着体に上塗りする方法や、硬化性樹脂からなる接着剤を欠損部分に充填する方法が行われている。   In order to protect against deterioration and corrosion of concrete and wood parts such as the outer walls, foundations, and pillars of buildings and detached houses, a method of coating the adherend with a material mixed with resin in cement and curability A method of filling a defective portion with an adhesive made of resin has been performed.

しかしながら、セメントに樹脂分を混入したとしてもセメント材を主剤としたものは、後に再度クラックが生じる場合も多く、被着体との密着性も好ましいものではなかった。一方、硬化性樹脂からなる接着剤等を使用する方法は、ひび割れ等に対して充填し水分の建造物内への進入を防止するという面では効果的であるが、接着剤自体が樹脂からなるため、セメント性の補強剤に比べてその強度が劣っており建造物自体の補強にはあまり寄与しないものであった。また、塗工において気温差による粘度の影響を受けやすく、均一な品質が得られないばかりか、粘度が低くなる場合は“液だれ”現象が起こり、その塗工技術が要求されるものであった。   However, even if the resin component is mixed in the cement, the material containing the cement material as a main agent often causes cracks again later, and the adhesion to the adherend is not preferable. On the other hand, the method of using an adhesive made of a curable resin is effective in terms of filling against cracks and preventing moisture from entering the building, but the adhesive itself is made of resin. Therefore, its strength is inferior to that of cement-based reinforcing agents, and it does not contribute much to the reinforcement of the building itself. In addition, the coating is easily influenced by the viscosity due to the temperature difference, so that uniform quality cannot be obtained, and when the viscosity becomes low, a “drip” phenomenon occurs, and the coating technology is required. It was.

これらの問題を解決する二液性建造物補強剤としてロックウールやガラス繊維を添加する技術（特許文献１や特許文献２）が開発されている。
特開２００３−２１３１３６号公報 特開２００３−２１３９３８号公報 Techniques (Patent Document 1 and Patent Document 2) in which rock wool or glass fiber is added as a two-component building reinforcing agent that solves these problems have been developed.
JP 2003-213136 A JP 2003-213938 A

しかしながら、より少量でより高い接着性や強度を与える建造物用補強剤の実現が望まれていた。そこで、本発明は、被着体となる建造物の基礎や外壁に対して、その表面に塗工するだけで常温で硬化し、被着体と一体となって建造物の強度や耐久性を向上させる建造物補強剤組成物であって、被着体に対する接着性や強度が高い二液性建造物補強剤組成物とその組成物に用いる硬化剤を得ることを目的としてなされたものである。 However, it has been desired to realize a reinforcing agent for buildings that gives higher adhesion and strength in a smaller amount. Therefore, the present invention cures at room temperature just by applying to the foundation and outer wall of the building to be attached, and the strength and durability of the building together with the adherend. a improved thereby building reinforced composition, which has been made in order to obtain a hardening agent that used in its composition adhesion property and high strength two-part building reinforcing composition to adherends It is.

以上の目的を達成するために本発明は、エポキシ樹脂組成物でなる主剤とアミン系硬化剤を混合してなり、コンクリートや木材からなる建物外壁や建物基礎等の建造物の表面に塗工して、建造物のひび割れや亀裂に浸透するとともに、該表面に塗工被膜を形成しつつ常温で主剤と硬化剤とが反応硬化し、該建造物と一体となって該建造物の強度や耐久性を向上させる二液性建造物補強剤組成物における硬化剤であって、主剤と硬化剤の混合物２０重量部に対して、アラミド繊維を０．１重量部〜０．３重量部含む硬化剤を提供する。 In order to achieve the above object, the present invention is a mixture of an epoxy resin composition main component and an amine curing agent, and is applied to the surface of a building such as a building outer wall or building foundation made of concrete or wood. The main agent and the curing agent react and cure at room temperature while forming a coating film on the surface and penetrate into cracks and cracks of the building, and the strength and durability of the building are integrated with the building. a curing agent in two-part building reinforcing agent composition for improving sexual, relative to the mixture 20 parts by weight of the main agent and the hardening agent, comprising 0.1 weight parts to 0.3 parts by weight of an aramid fiber A curing agent is provided.

主剤と硬化剤を混合して固化する二液性建造物補強剤組成物用の硬化剤について、アラミド繊維を含み、主剤がエポキシ樹脂組成物でなることとしたため、ロックウールなどの他の無機繊維や他の有機繊維を用いた場合に比べて固化物の強度が向上し、建造物の補強に優れている。 The curing agent for two-part building reinforcing agent composition solidified by mixing the base and curing agent, wherein the aramid textiles, because the base resin has a be in Epoxy resins compositions, other such rock wool Compared with the case of using inorganic fibers or other organic fibers, the strength of the solidified material is improved and the reinforcement of the building is excellent.

また、セメント材ではなく樹脂を主剤とするため、被着体となる建造物の外壁等のひび割れ、亀裂などの箇所に十分浸透するだけでなく、コンクリートや木材自体に浸透しやすいため、被着体との密着性に優れるとともに、被着体である建造物自体の強度向上、保護に寄与する。   In addition, since resin is used as the main agent instead of cement material, it not only penetrates into cracks and cracks on the outer wall of the building that is the adherend, but also easily penetrates into concrete and wood itself. In addition to excellent adhesion to the body, it contributes to improving the strength and protecting the structure itself, which is the adherend.

さらに、建造物表面に二液性建造物補強剤組成物による被膜が形成されるため、紫外線、酸性雨などから、建造物を保護することができ耐候性が向上する。さらに、水分の進入も防止することができるため、白アリ等の害虫の進入、発生を阻止することができる。   Furthermore, since a film of the two-component building reinforcing agent composition is formed on the building surface, the building can be protected from ultraviolet rays, acid rain, etc., and weather resistance is improved. Furthermore, since the ingress of moisture can be prevented, the invasion and generation of pests such as white ants can be prevented.

主剤にエポキシ樹脂組成物を用い、硬化剤にアミン系硬化剤を用いており、これらの成分の相互作用により、建造物を構成するコンクリートや木材に浸透して強固な固化物を得ることができる。また、作業時間中の固化は遅く、作業終了後の固化は早期に進むため、作業性が良い。 An epoxy resin composition in the main agent, and using an amine-based curing agent in the curing agent, the interaction of these components, it is possible to obtain a strong solidified product to penetrate into concrete or wood which constitute the building it can. Further, the solidification during the working time is slow, and the solidification after the completion of the work proceeds early, so that the workability is good.

主剤ではなく、硬化剤にアラミド繊維を含むので、粘度の低い硬化剤の粘度が上がり、主剤との粘度差が小さくなるため、作業現場での主剤と硬化剤の混合が容易になる。 Rather than the main agent, because it contains aramid textiles curing agent, increases the viscosity of the low cure agent viscosity, the viscosity difference of the base material is reduced, thereby facilitating the mixing of the main agent and the curing agent in the work site.

本発明の硬化剤を用いた二液性建造物補強剤組成物によれば、被着体となる建造物の基礎や外壁に対して、その表面に塗工するだけで、被着体と一体となって建造物の強度や耐久性を向上させることができる。さらに、二液性であるため保存性に優れるとともに、主剤、硬化剤及びその混合組成物の粘度を適度に調整できるため、作業現場における作業性に優れ、建造物の補強作業全体に対するコストパフォーマンスを向上させることが可能となる。 According to the two-component building reinforcing agent composition using the curing agent of the present invention, it is integrated with the adherend only by coating on the surface of the foundation or outer wall of the building to be attached. Thus, the strength and durability of the building can be improved. Furthermore, since it is two-component, it has excellent storage stability, and the viscosity of the main agent, curing agent and mixed composition can be adjusted appropriately, so it has excellent workability at the work site and cost performance for the entire reinforcement work of the building. It becomes possible to improve.

また、本発明の二液性建造物補強剤組成物用の硬化剤によれば、歩留まりの良い硬化剤とすることができる。また、主剤との粘度差を小さくすることができるため、作業現場での主剤との混合を容易にすることができる。   Moreover, according to the hardening | curing agent for the two-component building reinforcement agent composition of this invention, it can be set as a hardening agent with a sufficient yield. Moreover, since the difference in viscosity with the main agent can be reduced, mixing with the main agent at the work site can be facilitated.

以下、本発明の実施形態について以下詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail.

本発明の硬化剤を用いた二液性建造物補強剤組成物は、液状合成樹脂からなる主剤と、その主剤に常温で反応して鎖状又は網目状高分子を生成する硬化剤とからなる。二液性としたのは、塗工前は、保存性、安定性に優れ、塗工の際に簡単に調製でき、かつ塗工後も別段の作業なしに常温で即効的に硬化するという性質を有するからであり、保存性、作業面での容易性、そして、コストパフォーマンスに優れるからである。これに対し、一液性の補強剤では、十分な硬化（強度）が得られなかったり、硬化のために加熱等の後処理が必要であったり、硬化までに時間がかかったり、保存性が悪かったりといった問題がある。 From two-part construction creation reinforcing Additives Narubutsu using a curing agent of the present invention comprises a main agent consisting of liquid synthetic resin, and a curing agent which generates a chain or network polymer by reacting at room temperature in the main agent Become. The two-part nature is that it has excellent storage stability and stability before coating, can be easily prepared at the time of coating, and can be cured immediately at room temperature without any additional work after coating. This is because it has excellent storage stability, ease of work, and cost performance. On the other hand, with a one-component reinforcing agent, sufficient curing (strength) cannot be obtained, post-treatment such as heating is necessary for curing, curing takes time, and storage stability is high. There are problems such as being bad.

主剤は、液状合成樹脂であって、硬化剤と常温で反応するプレポリマーである。具体的には、エポキシ樹脂を主成分とする組成物を用いることができる。 The main agent is a liquid synthetic resin, which is a prepolymer that reacts with the curing agent at room temperature. Specifically, it is possible to use compositions based on epoxy resins.

エポキシ樹脂としては、例えば、ビスフェノールＡや、ビスフェノールＦ等のビスフェノール化合物、レゾルシン、ハイドロキノン等の多価フェノール、フェノールノボラック等のポリフェノール化合物と、エピクロルヒドリンとから誘導されるもの等が挙げられる。   Examples of the epoxy resin include those derived from bisphenol A and bisphenol compounds such as bisphenol F, polyphenols such as resorcin and hydroquinone, polyphenol compounds such as phenol novolac, and epichlorohydrin.

エポキシ樹脂が熱硬化性樹脂の中でも主剤と硬化材の反応バランスが取りやすい点や、グリシロールを添加することによって容易に主剤の粘度調整ができる点で好ましい。この主剤の粘度は、１０００ｍｐ.ｓ〜３０００ｍｐ.ｓ、好ましくは１０００ｍｐ.ｓ程度である。 And that tends to take the reaction balance base resin and the hardener Among et epoxy resin is a thermosetting resin is preferable in that it is a viscosity adjusted easily base material by the addition of Gurishiroru. The viscosity of the main agent is about 1000 mp.s to 3000 mp.s, preferably about 1000 mp.s.

硬化剤は、主剤と反応して硬化物を得るものである。主剤にエポキシ樹脂を用いた場合の硬化剤は、アミン系物質であり、例えば、フェニレンジアミンやトリレンジアミン等の芳香族多価アミン、脂肪族多価アミン、ポリアミドアミン類等の変性アミン類が挙げられる。 Curing agent, Ru der to obtain a cured product by reacting a base material. Curing agent in the case of using the epoxy resin in the main agent is an amine-based materials, for example, aromatic such as phenylene diamine and triethylene diamine polyvalent amine, aliphatic polyamine, modified amines such as polyamidoamines Is mentioned .

主剤または硬化剤、あるいはその双方には、ヤシ繊維、ビニロン、ナイロン、ポリエステル、アラミドなどの有機繊維や、アルミ繊維、ガラス繊維、ロックウールなどの無機繊維、シリカなどの無機粉末などの添加剤を添加して二液性建造物補強剤組成物の強度向上を図ることができる。   Additives such as organic fibers such as palm fiber, vinylon, nylon, polyester, and aramid, inorganic fibers such as aluminum fiber, glass fiber, rock wool, and inorganic powder such as silica are added to the main agent and / or curing agent. Addition can improve the strength of the two-component building reinforcing agent composition.

主剤や硬化剤、またはこれらの双方に添加するアラミド繊維の長さは１.５ｍｍ〜２５ｍｍ、太さは１０μｍ〜０.１ｍｍである。この程度の長さのものは、硬化剤へ添加すれば粘度増加が顕著であることや市場で入手し易く安価であるため好ましいが、１.５ｍｍより短いと増粘効果が小さく、強度の向上効果が不十分であり、２５ｍｍを超えると分散が困難である。また、太さが１０μｍより細いか０.１ｍｍより太いものは添加量に対する強度の増加効果に乏しい。 Main agent and the curing agent or the length of the aramid textiles to be added to these both are 1.5Mm～25mm, thickness is 10Myuemu～0.1Mm. The length of this level is preferable because if added to the curing agent, the increase in viscosity is remarkable and it is easy to obtain in the market and inexpensive, but if it is shorter than 1.5 mm, the thickening effect is small and the strength is improved. The effect is insufficient, and dispersion is difficult when it exceeds 25 mm. Further, when the thickness is thinner than 10 μm or thicker than 0.1 mm, the effect of increasing the strength with respect to the added amount is poor.

また、シリカは、平均粒径が３２５メッシュ〜１０メッシュ、好ましくは、１００メッシュ〜４８メッシュであり、剛性の向上、塗装面を美しく仕上げること及び耐熱性、長面性、クラック防止が図られるという特徴があるシリカである。尚、平均粒径が３２５メッシュより小さいものは分散が困難であり、１０メッシュより大きいものは強度の増加効果に乏しい。 Further, Shi silica has an average particle size of 325 mesh to 10 mesh, preferably a 100 mesh to 48 mesh, improves the rigidity, it beautiful finish painted surfaces and heat resistance, long surface resistance, anti-cracking can be achieved It is a silica with the characteristics. In addition, it is difficult to disperse those having an average particle size smaller than 325 mesh, and those having an average particle size larger than 10 mesh are poor in increasing the strength.

また、ガラス繊維などの無機繊維の長さは１.５ｍｍ〜２５ｍｍ、太さは１０μｍ〜０.１ｍｍである。１.５ｍｍより短いと硬化剤に添加した場合の増粘効果が小さく、強度の向上効果が不十分であり、２５ｍｍを越えると分散が困難で塗布むらが生じることがある。太さが１０μｍより細いか０.１ｍｍより太いものは添加量に対する強度の増加効果に乏しい。 The length of inorganic fibers such as glass fibers 1.5Mm～25mm, the thickness is 10Myuemu～0.1Mm. If it is shorter than 1.5 mm, the thickening effect when added to the curing agent is small and the effect of improving the strength is insufficient, and if it exceeds 25 mm, dispersion is difficult and uneven coating may occur. When the thickness is thinner than 10 μm or thicker than 0.1 mm, the effect of increasing the strength with respect to the added amount is poor.

これらの添加剤の中では、アラミド繊維や、シリカを用いることが、同量の他の有機繊維や無機繊維を混入させた場合に比べて１０％〜３０％の強度増大が認められる点で好ましい。また、ガラス繊維にシリカが混ざることで、線から面の塗膜が形成され、一層強度が図られる。   Among these additives, it is preferable to use an aramid fiber or silica in view of an increase in strength of 10% to 30% compared to the case where the same amount of another organic fiber or inorganic fiber is mixed. . Moreover, the silica is mixed with the glass fiber, whereby a coating film is formed from the line to the surface, and the strength is further increased.

上記添加剤の混合比（重量）は、主剤と硬化剤の混合物２０重量部に対して、アラミド繊維などの有機繊維の場合は０.１重量部〜０.３重量部、好ましくは０.２重量部である。また、ガラス繊維などの無機繊維の場合は０.３重量部〜０.５重量部、好ましくは０.４重量部である。さらにシリカは、０.６重量部〜１.８重量部、好ましくは１.２重量部である。有機繊維で０．３重量部、無機繊維で０．５重量部、シリカで１.８重量部より多いと粘度が高くなりすぎる場合がある。また、有機繊維で０.１重量部、無機繊維で０.３重量部、シリカで０．６重量部より少なければ添加効果が十分ではない。 The mixing ratio (weight) of the above additives is 0.1 parts by weight to 0.3 parts by weight, preferably 0.2 parts by weight in the case of organic fibers such as aramid fibers with respect to 20 parts by weight of the mixture of the main agent and the curing agent. Parts by weight. In the case of inorganic fibers such as glass fiber, the amount is 0.3 to 0.5 parts by weight, preferably 0.4 parts by weight. Further, the amount of silica is 0.6 to 1.8 parts by weight, preferably 1.2 parts by weight. If it is more than 0.3 parts by weight with organic fibers, 0.5 parts by weight with inorganic fibers and 1.8 parts by weight with silica, the viscosity may be too high. Moreover, the addition effect is not sufficient if it is less than 0.1 part by weight of organic fiber, 0.3 part by weight of inorganic fiber and 0.6 part by weight of silica.

繊維状物質やシリカと、二液性建造物補強剤組成物やその主剤、または硬化剤との混合は、例えばオムニミキサーにより行うことができ、通常３分〜１０分、好ましくは５分前後混合することにより行われる。   The fibrous material or silica can be mixed with the two-component building reinforcing agent composition or the main agent or the curing agent, for example, with an omni mixer, and usually mixed for about 3 minutes to 10 minutes, preferably about 5 minutes. Is done.

硬化剤の粘度は、上記有機繊維などの添加剤を加えて主剤の粘度に同程度とすることが可能であり、５０ｍｐ.ｓ〜１００ｍｐ.ｓ、好ましくは５０ｍｐ.ｓとすることができる。上記添加剤を加えれば、加えない場合に比べて粘度が高くなるため、作業現場における主剤と硬化剤の混合が容易かつ確実に行うことができる。主剤の粘度が高すぎる場合には、主剤と混合し易い軟化剤を添加することにより、作業現場において適宜粘度調整をすることができる。   The viscosity of the curing agent can be made approximately the same as the viscosity of the main agent by adding an additive such as the above organic fiber, and can be 50 mp.s to 100 mp.s, preferably 50 mp.s. If the additive is added, the viscosity becomes higher than when the additive is not added, so that the main agent and the curing agent can be easily and reliably mixed at the work site. When the viscosity of the main agent is too high, the viscosity can be appropriately adjusted at the work site by adding a softening agent that is easily mixed with the main agent.

主剤と硬化剤の混合比（重量）は、主剤と硬化剤の種類や組合せにより変化するが、主剤にエポキシ系樹脂を用い、硬化剤にアミン系硬化剤を用いた場合は、主剤：硬化剤＝１００：５０〜１００：３５である。硬化剤の主剤に対する混合比は、これより多くても少なくても硬化が不十分となるため好ましくない。両者の混合は、手混ぜかハンドミキサーで作業現場にて簡単に行うことができる。主剤と硬化剤を混合した直後の混合物の粘度は、７００ｍｐ.ｓ〜１１００ｍｐ.ｓ、好ましくは、１０００ｍｐ.ｓ程度とすることができる。これは、上記添加剤を加えないである程度の強度を発生させる従来品の粘度が通常１５００ｍｐ.ｓ〜２０００ｍｐ.ｓであり、夏場で３０００ｍｐ.ｓ、冬場で１００００ｍｐ.ｓになるのと比べて粘度を低く保つことができ、塗工作業が容易で作業効率が向上する。   The mixing ratio (weight) of the main agent and the curing agent varies depending on the type and combination of the main agent and the curing agent, but when an epoxy resin is used as the main agent and an amine curing agent is used as the curing agent, the main agent: the curing agent. = 100: 50 to 100: 35. If the mixing ratio of the curing agent to the main agent is larger or smaller than this, the curing becomes insufficient, which is not preferable. Both can be easily mixed at the work site by hand mixing or hand mixing. The viscosity of the mixture immediately after mixing the main agent and the curing agent is 700 mp.s to 1100 mp.s, preferably about 1000 mp.s. This is because the viscosity of a conventional product that generates a certain degree of strength without adding the above additives is usually 1500 mp.s to 2000 mp.s, which is 3000 mp.s in summer and 10000 mp.s in winter. Can be kept low, coating work is easy and work efficiency is improved.

なお、主剤又は硬化剤には、必要に応じて着色顔料や体質顔料、表面調整剤、消泡剤、分散剤、可塑剤、溶剤、硬化触媒、染料、湿潤剤、レベリング剤等を適宜添加してもよい。着色顔料を加えたものは、建造物の補強だけでなく、外観の美化にも有益である。   In addition, coloring pigments, extender pigments, surface conditioners, antifoaming agents, dispersants, plasticizers, solvents, curing catalysts, dyes, wetting agents, leveling agents, etc. are appropriately added to the main agent or curing agent as necessary. May be. The addition of the color pigment is useful not only for reinforcing the building but also for beautifying the appearance.

二液性建造物補強剤組成物を路面に対して施工するような場合には、塗工後、この補強剤組成物が固化するまでの間にガラス粒や、砂粒、アルミ粉、セラミック粉のような滑り止め材を施工面に散布することにより、施工面の質感を変化させると共に、滑り止めに役立てることができる。滑り止め材の粒径は、直径φ＝０.１〜３ｍｍが好ましく、滑り止め材の添加量は、樹脂量の５％〜１５％が好ましい。   When a two-component building reinforcing agent composition is applied to the road surface, the glass particles, sand particles, aluminum powder, ceramic powder, etc., after coating, until the reinforcing agent composition solidifies. By spreading such a non-slip material on the construction surface, it is possible to change the texture of the construction surface and to help prevent the slip. The particle diameter of the anti-slip material is preferably a diameter φ = 0.1 to 3 mm, and the addition amount of the anti-slip material is preferably 5% to 15% of the resin amount.

本発明を適用しうる建造物は、コンクリート製、木製の建造物が主であるが、これらの材質に限られず、タイルや人工大理石などを用いたものに対しても優れた補強効果を発揮する。また、建造物には、ビル、戸建住宅などのような建物の外壁や基礎、柱等の建物自体に限られず、浴室、洗面所、トイレの土台周り等の建物に用いられる部材に対しても適用可能である。   Buildings to which the present invention can be applied are mainly concrete and wooden buildings, but are not limited to these materials, and exhibit excellent reinforcing effects even for those using tiles or artificial marble. . In addition, the building is not limited to the building itself such as a building or a detached house, such as a building, a foundation, a pillar, etc. Is also applicable.

二液性建造物補強剤組成物は、図１に示すように主剤又は硬化剤の何れかに添加剤を加えオムニミキサーにて５分間攪拌して添加剤を混合しておいた。次に、主剤と硬化剤を回転式攪拌機にて混合攪拌して二液性建造物補強剤組成物を得た。得られた二液性建造物補強剤組成物をコンクリート製の建物の外壁にゴムヘラにて塗工した後、約２〜３時間放置して硬化させた。試料１〜試料３の二液性建造物補強剤組成物を用いたものは、被着体である外壁のクラックが埋められるとともに、外壁自体へも二液性建造物補強剤組成物が浸透し、強固な外壁が得られた。一方、試料４〜試料６の二液性建造物補強剤組成物を用いたものは、クラックが埋まり、外壁自体への浸透もあったが、試料５の二液性建造物補強剤組成物はやや外壁の強度が劣り、試料４と試料６の二液性建造物補強剤組成物では強固な外壁は得られなかった。 As shown in FIG. 1, the two- component building reinforcing agent composition was prepared by adding an additive to either the main agent or the curing agent and stirring the mixture for 5 minutes using an omni mixer. Next, the main agent and the curing agent were mixed and stirred with a rotary stirrer to obtain a two-component building reinforcing agent composition. The obtained two-component building reinforcing agent composition was applied to the outer wall of a concrete building with a rubber spatula and then allowed to stand for about 2-3 hours to be cured. Samples 1 to 3 using the two-component building reinforcing agent composition are filled with cracks on the outer wall as the adherend, and the two-component building reinforcing agent composition penetrates the outer wall itself. A strong outer wall was obtained. On the other hand, the samples using Sample 4 to Sample 6 using the two-component building reinforcing agent composition were filled with cracks and penetrated into the outer wall itself, but the two-component building reinforcing agent composition of Sample 5 was The strength of the outer wall was slightly inferior, and the two-part building reinforcing agent composition of Sample 4 and Sample 6 did not provide a strong outer wall.

なお、この二液性建造物補強剤組成物を用いてＪＩＳ−Ａ１１０６に基づくコンクリート曲げ強度試験を行った。幅×長さ×高さ＝１５０ｍｍ×５３０ｍｍ×１５０ｍｍのＢ．Ｂセメント試料に厚さ１ｍｍとなるように上記二液性建造物補強剤組成物を塗布して曲げ強度を測定した。その結果も図１に示す。   In addition, the concrete bending strength test based on JIS-A1106 was done using this two-component building reinforcement agent composition. Width × length × height = 150 mm × 530 mm × 150 mm The above two-component building reinforcing agent composition was applied to a B cement sample to a thickness of 1 mm, and the bending strength was measured. The results are also shown in FIG.

曲げ強度試験の結果から、アラミド繊維を混入した試料１や試料２の二液性建造物補強剤組成物は、主剤と硬化剤の他に添加剤を全く含まない試料４の二液性建造物補強剤組成物や、アラミド繊維以外の有機繊維であるポリエステル繊維を混入した試料５の二液性建造物補強剤組成物に比較して、強度向上がはっきりと認められた。 From the results of the bending strength test, the two-component building reinforcing agent composition of Sample 1 or Sample 2 mixed with aramid fiber is the two-component building of Sample 4 which contains no additive in addition to the main agent and the curing agent. A strength improvement was clearly recognized as compared with the two-component building reinforcing agent composition of Sample 5 in which the reinforcing agent composition and polyester fibers which are organic fibers other than aramid fibers were mixed.

また、ガラス繊維とシリカを混入した試料３の二液性建造物補強剤組成物も、ガラス繊維だけを含みシリカを含まない試料６の二液性建造物補強剤組成物に比較して、強度向上がはっきりと認められた。 In addition, the two-component building reinforcing agent composition of Sample 3 mixed with glass fiber and silica is stronger than the two-component building reinforcing agent composition of Sample 6 that contains only glass fibers and does not contain silica. The improvement was clearly recognized.
