Penetrating-consolidant Repair Material

Penetrating-Consolidant
Repair Material

This material has excellent penetration properties and can penetrate into the cracks and pores of concrete and solidify and cross-link in situ, firmly bonding damaged and failed concrete together to form a three-dimensional spatial solidification body equivalent to an interpenetrating network structure, thereby achieving rapid repair and reinforcement of concrete. In particular, this material can directly consolidate fine sand, soft mud, gravel, etc. into rock (compressive strength >100 MPa).

Deep-Penetration Surface Protection Mechanism

When this material is used for surface protection, it not only forms a coating on the surface of the concrete, but also forms a “rooted” consolidation reinforcement layer deep into the structural layer, thus eliminating capillaries, pores and micro-cracks formed by the porous media of the concrete, making the anti-corrosion layer on the surface of the concrete as thick as millimeters, increasing the surface strength of the concrete by more than twice, and having excellent corrosion resistance and anti-penetration properties.

Applications

At present, this technology has been widely used in the reinforcement, waterproofing, anti-seepage, and anti-corrosion of:
  • Subways
  • Tunnels
  • Bridges
  • Seaports and terminals
  • Hydropower dams
  • Civil buildings
This achievement can effectively improve the mechanical properties, impermeability and durability of concrete, and has important application value in national large-scale projects, industrial construction, civil construction and other fields.

Key Technical Indicators

  • Initial viscosity: <30 mPa.s
  • Operation time: 1-24 h
  • Compressive strength: >100 MPa (close to ultra-high performance concrete)
  • Bonding strength:
    • Dry bonding >4.0MPa
    • Wet bonding >3.5MPa
    • Both cause concrete damage before failure
  • Corrosion resistance: No cracking, peeling or deterioration after 90 days immersion in:
    • 10wt% H2SO4 (acid)
    • 10wt% NaOH (alkali)
    • 10wt% NaCl (salt)
