Pre-Stressing Duct Grout is a cement-based dry powder designed for prestressed duct grouting. After mixing with water, it forms a high-fluidity, non-bleeding grout with stable performance. The product ensures dense filling of ducts and provides effective bonding and protection for prestressing tendons, improving structural durability.
