Highly ductile concrete
Highly ductile concrete
◆ 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.
◆ Self-compacting: strong anti-segregation ability, no need for tamping and vibration.
◆ Fire resistance: fiber dissolves at high temperature, forming water vapor migration channels to release vapor and prevent cement matrix decomposition and damage.
◆ Self-healing: strong ability to self-repair, increasing component durability in changing environments.
◆ Good environmental performance: reduced CO2 emissions, improved energy efficiency.

Bendable concrete used for seismic retrofitting by scraped or pumped
Keywords:
classification:
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.
◆ 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.
◆ Self-compacting: strong anti-segregation ability, no need for tamping and vibration.
◆ Fire resistance: fiber dissolves at high temperature, forming water vapor migration channels to release vapor and prevent cement matrix decomposition and damage.
◆ Self-healing: strong ability to self-repair, increasing component durability in changing environments.
◆ Good environmental performance: reduced CO2 emissions, improved energy efficiency.
