Structural concrete HIGHLY DUCTILE

fire-retardantimpact-resistantself-consolidating

Bendable concrete used for seismic retrofitting by scraped or pumped Usage: ◆ It is suitable for external layer structural engineering reinforcement of high ductility polymer mortar. ◆ Seismic reinforcement and reconstruction of reinforced concrete beams, columns, plates, walls and other structures. ◆ It is suitable for all structures with easy bending structure, especially for the slab and beam of reinforced concrete bridge, a representative bending structure of civil architecture. ◆ It is applicable to the cracked parts of pier, main tower shaft and expressway cement pavement. It has the same system as the previous reinforced concrete structures. ◆ When honeycomb, loophole, crack, protective layer damage, reinforcement leakage and other defects appear in the concrete, the surface repair works shall be carried out. ◆ Thicken the protective layer, smooth the concave convex surface and repair the old concrete surface to improve the durability of the concrete. Advantage ◆ Bending performance: deflection hardening characteristics; fine fractional joints. ◆ Multi-crack construction, also known as “bendable concrete,” allows cracks without damage. ◆ Tensile properties: strain hardening during tension; maintains strength after cracking; ultimate tensile strain over 100 times ordinary concrete. ◆ High fatigue resistance and impact resistance. ◆ Obvious seismic reinforcement effect. ◆ Fast and convenient construction, short construction period; lower comprehensive cost than traditional reinforcement scheme. ◆ Fire resistance: fiber dissolves at high temperature, forming water vapor migration channels to release vapor and prevent cement matrix decomposition and damage.
