Description
【発明の詳細な説明】 産業上の利用分野 本発明は、セメント用無塩素防水剤に関する。[Detailed description of the invention] Industrial applications The present invention relates to a chlorine-free waterproofing agent for cement.
従来の技術及びその問題点
セメント組成物中に配合して、セメント硬化物の防水性
能を向上させる物質、所謂セメント用防水剤としては、
有機質系防水剤として微粒子状の溌水性有機物質、無機
質系防水剤として８挿の無機塩等が知られている。Conventional techniques and their problems Substances that are blended into cement compositions to improve the waterproof performance of cured cement products, so-called waterproofing agents for cement, include:
Particulate water-repellent organic substances are known as organic waterproofing agents, and inorganic salts are known as inorganic waterproofing agents.
これらのうち有機物系の防水剤は、防水性能は浸れてい
るものの、高価であり、更に、分解し易いのでこれを配
合したセメント硬化物は耐用年数が短いという欠点もあ
り、一般には余り使用されていない。Among these, organic waterproofing agents have good waterproofing performance, but they are expensive, and furthermore, they are easily decomposed, so cement hardened products containing them have a short service life, so they are not generally used. Not yet.
一方、無ｍ質系の防水剤としては、ＣａＣＯ２が汎用さ
れているが、ＣａＣＯ２は、鉄に対する腐食作用が大き
く、このためＣａＣＯ２を配合したセメンｉ〜組成物を
鉄筋コンクリート用のコンクリートとして用いると、鉄
筋を腐食して強度を低下させるという問題点がある。ま
た、ＣａＣＯ２の水溶液は、強い酸性であり、セメント
と混合すると中和反応による発熱によって急激な水分の
蒸発が生じ、セメント硬化物に亀裂が生じ易く、その結
果防水性能が不充分となるという欠点もある。On the other hand, CaCO2 is commonly used as an amorphous waterproofing agent, but CaCO2 has a strong corrosive effect on iron, so if a cement i composition containing CaCO2 is used as concrete for reinforced concrete, There is a problem in that it corrodes the reinforcing steel and reduces its strength. In addition, an aqueous solution of CaCO2 is strongly acidic, and when mixed with cement, the heat generated by the neutralization reaction causes rapid evaporation of water, which tends to cause cracks in the cured cement, resulting in insufficient waterproof performance. There is also.
そこでＣａＣＯ２とＣａＣＯ３とを併用して、水溶液を
中性に近くして、セメントとの混和時の急激な反応を防
止しようとする試みがなされているが、この場合にもや
はりＣａＣＯ２を使用するので鉄に対する腐食性の問題
は解消されていない。Therefore, attempts have been made to use a combination of CaCO2 and CaCO3 to make the aqueous solution close to neutrality and prevent rapid reactions when mixed with cement, but in this case as well, CaCO2 is used. The problem of corrosivity to iron remains unresolved.
また、チオ硫酸ナトリウムを防水剤として使用する試み
もなされているが、チオ硫酸ナトリウムは、徐々に分解
して、硫化物を形成する性質があり、セメント硬化物の
耐用年数が短くなるという欠点がある。Attempts have also been made to use sodium thiosulfate as a waterproofing agent, but sodium thiosulfate has the property of gradually decomposing and forming sulfides, which has the disadvantage of shortening the service life of cement hardened products. be.
問題点を解決するための手段

また、これらの防水剤は、鉄に対する腐食性がなく、し
かも匁定であり、セメント硬化物の耐久性を低下させる
こともないことを見出した。Means for Solving the Problems The present inventor has conducted extensive research in view of the problems of the prior art as described above. As a result, water-soluble cyano complex salt,

本発明の防水剤である水溶性シアノ錯塩、水溶性チオシ
アン１ヒ物及び水溶性フッ化物は、いずれもセメント組
成物を急激に硬化させることなく、セメント硬化物の組
織を緻茫にして水の侵入を防止する働きをする。また之
等の防水剤は、鉄に対する腐蝕性がなく、しかもセメン
ト硬化物中で分解してセメント硬化物の耐久性を低下さ
せることもない。The water-soluble cyano complex, the water-soluble thiocyanate, and the water-soluble fluoride, which are the waterproofing agents of the present invention, all do not harden the cement composition rapidly and make the structure of the hardened cement material dense, allowing water to flow through the water. Works to prevent intrusion. In addition, these waterproofing agents are not corrosive to iron and do not decompose in hardened cement products to reduce the durability of hardened cement products.

, φ12mIIIXQ1501111m, and left to dry at room temperature for 40 hours to produce a concrete rod. In addition, as a comparison product, a concrete bar was produced using a raw material having the same composition except that it did not contain potassium hexacyanoate. One block of these concrete rods was immersed in water to a depth of 2 cm, and the height of water sucked up by both concrete rods was measured at 5 minute intervals over an hour to determine the ease with which water penetrated. compared.
その結末、吸い上げられた水の高さの比率は、平均して

After leaving it to dry for about 40 hours, water was poured in and the state of water penetration was observed. did. As a result, no water penetration was observed even after 120 hours had passed. On the other hand, when a mortar composition containing no potassium hexacyanoferrate was used, a large amount of water permeated after 5 hours.

A concrete rod and a mortar composition were prepared, and the height of water uptake of the concrete rod and the state of water seepage from the box-shaped container were observed. As a result, the water absorption height of the concrete rod was 0.43:1 compared to the concrete rod that did not contain the above waterproofing agent component (product of the present invention: comparative product).
Also, no water leakage from the box-shaped container was observed.

The condition of water leakage from the box-shaped container was observed. As a result, the height of water wicking from the concrete rod was 0.43:1 (inventive product: comparison product) compared to the concrete rod that did not contain the above-mentioned waterproofing agent component, and the height of water absorption from the box-shaped container was No water seepage was observed.
