How Does the Weight of UHPC Curtain Wall Panels Compare to Stone Curtain Wall Panels? Analysis of UHPC's Lightweight Advantages

UHPC curtain wall panels weigh only 1/3-1/2 of natural stone, greatly reducing structural loads. Taking a 20mm thick panel as an example, a UHPC panel has a surface density of 48kg/㎡, while a 30mm thick granite panel has a surface density of 84kg/㎡, a weight reduction of 43%. This lightweight advantage significantly lowers main structure costs and improves seismic performance.

In terms of weight comparison, UHPC has a density of 2400kg/m³, while stone has a density of 2600-2800kg/m³. However, thanks to UHPC's high strength, it can be made thinner and therefore lighter. For example, under the same wind pressure resistance requirements, a UHPC panel only needs to be 20mm thick, while stone requires 30mm, reducing weight by 36%. This advantage is particularly evident in high-rise buildings and the renovation of old buildings, reducing the need for structural reinforcement and saving on total investment.

Material Density Comparison

UHPC density: 2400kg/m³; stone density: 2600-2800kg/m³; UHPC is lighter.

Impact of Panel Thickness Differences

UHPC panels are thinner at equal strength; a 20mm UHPC panel is equivalent to a 30mm stone panel; thickness differences lead to weight differences.

Weight Reduction Ratio

UHPC panels weigh 1/3-1/2 of stone; a reduction of over 43%; a clear lightweight advantage.

Economic Benefit Analysis

Reduced loads lower structural costs; reduced transport and installation costs; these benefits are significant.

Lightweight design is a significant advantage of UHPC. Qinglong UHPC is lightweight and high-strength, creating value for customers.
