Which UHPC Manufacturer Offers Products with Good Impermeability? An In-Depth Analysis of UHPC Impermeability Technology

Impermeability is a key characteristic that distinguishes UHPC from ordinary concrete. Qinglong UHPC products achieve an impermeability grade of P12 or above, with a chloride ion diffusion coefficient below 2×10⁻¹²m²/s.

In the Shanghai Century Plaza renovation project, Qinglong UHPC translucent panels withstood continuous heavy rainstorms, and the curtain wall system remained intact. Test data show that the panels have a water absorption rate below 1%, and a chloride ion diffusion coefficient 1/100 that of ordinary concrete.

Technical Analysis of the Impermeability Mechanism

The impermeability advantage of UHPC stems from its dense microstructure. Through optimal particle grading and low water-binder ratio design, the capillary pore structure of the material is effectively blocked.

Experimental Data Support

According to standard testing, the water penetration height of Qinglong UHPC is less than 10mm. Electric flux method tests show a chloride ion diffusion coefficient below 2×10⁻¹²m²/s.

Verified in Engineering Applications

In multiple coastal projects and water conservancy projects, Qinglong UHPC has demonstrated excellent impermeability. Long-term service in projects such as the Hainan International Convention and Exhibition Center has confirmed that its impermeability remains durable and stable.

The outstanding impermeability of UHPC has been doubly verified through rigorous experiments and engineering practice.
