Scope of use of UHPC curtain wall panels

The basic raw materials of UHPC are not unfamiliar to those familiar with concrete: water, sand, cement, silica fume, and additives. It sounds simple, but compared to ordinary concrete, UHPC is of a different order of magnitude. There are no mysterious ingredients: resins, cellulose, or special polymers are not used to achieve performance, and the secret lies in the chemical and geometric properties of ultrafine particles and carefully selected particles, which are properly stirred, poured, and cured to achieve a close accumulation of the matrix and strong molecular binding force. UHPC curtain wall panels not only have ultra-high strength and durability, but through correct processing methods and processes, they can provide solutions that meet the needs of high specification building components, creative architectural design inspiration, and economy.

1、 Characteristics of UHPC curtain wall panels

The color is beautiful, and UHPC can display rich overall colors by calculating the proportion of mineral pigments added.

UHPC curtain wall panels have strong chemical stability and corrosion resistance, and can be exposed to various corrosive environments. They exhibit high resistance to acidic media, and have a smooth and high-density surface, with strong waterproof, anti fouling, and anti fouling capabilities.

The design has strong plasticity. Due to the strong performance of UHPC hanging boards, it can achieve various irregular shapes of ultra-high building vacancy rates, as well as achieve single piece products with ultra large and ultra large span curved surfaces, which can greatly ensure the smoothness and aesthetics of the surface design of curtain walls. This is an advantage that ordinary GRC and other curtain wall materials cannot compare.

The anti pollution performance of UHPC products is mainly based on two reasons. Firstly, their inherent density and ultra-low porosity can make UHPC products resistant to stains and chemical corrosion. Chloride ion intrusion; The second method is to use UHPC protective agent to achieve surface hydrophobicity and enhance stain resistance.

2、 Applicable scope of UHPC curtain wall panels

1. By utilizing the high strength of UHPC, the size of structural components can be reduced and more usable space can be obtained. UHPC can be used to build bridges with longer spans and larger clearances; It can reduce the cross-sectional size of the bottom column in high-rise buildings and obtain more usable area.

2. By utilizing the high tensile strength and corrosion resistance properties of UHPC, oil and gas pipelines can be made to replace expensive large diameter thick walled steel pipes, significantly improving pipeline durability.

3. Utilize the high impermeability of UHPC to manufacture integrated containers for storing medium to low radioactive nuclear waste.

4. Used in the field of security, manufacturing anti explosion and anti impact devices.

5. On site repair, structural reinforcement, etc.
