32nd Anniversary Concrete Modifier CS-21
■Today, May 9, marks the anniversary of the development of the 'CS-21', which is the foundation of the CS-21 series products. ■The CS-21 series products (liquid and reactive silicate-based surface impregnants) are applied to hardened concrete surfaces to fill fine cracks and voids, such as construction joints, that are difficult to see visually from the surface, thereby densifying the surface layer. Additionally, through ongoing reactions under moisture supply from rainwater and other sources, they fill newly generated fine voids after application, suppressing the progression and expansion of cracks. These properties help maintain the integrity of the cover concrete and suppress the intrusion of water and various deterioration factors (steel corrosion) over the long term. ■Construction achievements of the CS-21 series products: 2,824 cases (from Hokkaido to Okinawa) - By method > Surface protection: 1,128 cases (630,000 m²), etc. - By client > Ministry of Land, Infrastructure, Transport and Tourism: 448 cases, other public: 1,060 cases, etc. - Aggregation period: 2002 to September 2024 *Construction achievement table → https://www.cs21.jp/top/documents/ ■For inquiries ↓ Aston Association Member List (from Hokkaido to Okinawa) https://note.com/aston_cs21/n/n7d264922339c

CS-21 has been certified as a material by JR West.
The results of a test exposure lasting approximately 7.5 years under harsh conditions in the JR West Japan area, characterized by warm temperatures, high rainfall, and ample sunlight along the coast, have shown that "CS-21" meets the required performance standards sought by the company, thus becoming a certified material for repairing initial defects in newly constructed concrete structures.

Website renewal (cs21.jp)
We have renewed the Aston official website (cs21.jp). On the top page, we have added "CS-21 series products and construction method examples corresponding to usage purposes," making it easier to find materials by product and usage purpose. *Automatic calculation of material usage https://www.cs21.jp/top/method/calculate/ By entering "application amount," "loss rate," and "construction area," the required quantity (kg, number of cans) can be calculated.
