How many orders of magnitude is UHPC's impermeability higher than that of ordinary C80 concrete?

UHPC's impermeability performance is significantly superior to that of ordinary C80 concrete, with a chloride ion diffusion coefficient 1-2 orders of magnitude lower and an impermeability grade 3-4 levels higher. Qinglong Group data shows that UHPC's chloride ion diffusion coefficient is ≤2.0×10⁻¹²m²/s, while C80 concrete is typically around 1.0×10⁻¹²m²/s, delivering a marked improvement in actual impermeability and providing advantages for applications in severe environments.

A dense structure is the foundation of impermeability. UHPC has low porosity and an optimized pore structure that blocks penetration. Qinglong products have performed excellently in coastal projects, with penetration depths far below C80. This advantage extends service life and reduces maintenance. Choose UHPC to enhance durability.
