HWG-1 Anticorrosion Sealant（ pump Recommended by competent manufacturers
Preferential purchase for production base of concrete anticorrosive gas sealant
Necessity of using anticorrosive air sealing agent in concrete Concrete durability is an important standard for modern high-performance green concrete, which includes technical indicators such as crack resistance, reinforcement protection, corrosion resistance, frost resistance, impermeability, corrosion resistance, alkali aggregate reactivity, and all kinds of performances complement each other and interact with each other.
According to (TJS [2005] No. 157) Temporary Provisions for Durability Design of * * * Concrete Structures, TB10120-2002, J160-2002 Technical Code for * * * Gas Tunnel GBJ82-85, GB/T2420-1981 and other executive standards.
