Measures for extending the lifespan of existing concrete.
"CS-21 Builder" is a two-component reactive silicate-based surface impregnation material that is used by mixing a main agent with an additive primarily composed of calcium hydroxide, which is often lacking in existing concrete. It maintains a liquid state for a certain period after mixing, gelifying and remaining within the penetrated voids. The generation of reaction products continues, filling newly formed fine cracks and other voids, suppressing the intrusion of deterioration factors, and contributing to increased longevity. 【Features】 ■ Forced reaction promotion ■ Shortened construction period ■ Particularly effective for carbonated concrete ■ Cost reduction *For more details, please download the PDF or feel free to contact us.
