RC Anti-carbonation

Above RC block had been half left coated with WGC Photocatalyst solution and another right half uncoated.
We have soaked it into strong acid water for one day and compared with each sides.

Half left side,coated with WGC Photocatalyst solution remain good condition. On the other hand, half right side had obviously been carbonated.

Concrete buildings are gradually carbonated and black fungus etc appears as aged deterioration progresses. The inside of the concrete is originally alkaline however, rainwater (acid rain) etc. penetrate into it, gradually progressing to neutralization = carbonated.

The WGC coating agent prevents water from penetrating into concrete, and at the same time, it decomposes dirt, exhaust gas and oil stains on the concrete surface thus you can keep concrete building in good condition without less maintenance for a long time.


コンクリート建築物は徐々に劣化(中性化)し、黒い菌などが現れます。 これは汚れの原因となり美観が失われます。上記は左半分をWGCコーティングし、右半分を無塗装したコンクリート片を一日、塩酸に浸した画像です。右側は劣化が著しく砂状にぼろぼろになっているのがわかります。コンクリートの内部は元々アルカリ性ですが、雨水(酸性雨)などが浸透し、徐々に中和=劣化に繋がります。WGCコーティング剤は、水がコンクリートの中に浸透するのを防止すると同時に、コンクリート表面上の汚れ、排ガスおよび油の汚れを分解しますので何年も綺麗な状態を保持する事が可能です。
