Weight Difference Analysis of UHPC Panels by Thickness: Qinglong Measured Data Reference

The weight differences of UHPC panels directly affect building load design and installation plan selection, and the weight variations across different thicknesses follow clear patterns. As an enterprise with material testing capabilities, Qinglong Group combines measured data with production experience to analyze the weight differences of UHPC panels of different thicknesses and their engineering significance.

I. Weight Calculation Basis and Core Parameters The weight calculation of UHPC panels is based on their volumetric density. The volumetric density of high-quality UHPC is approximately 2400-2500kg/m³, slightly higher than ordinary concrete (2300-2400kg/m³), which stems from its high compactness and steel fiber addition. The weight calculation formula is: Weight (kg) = Thickness (m) × Area (m²) × Volumetric Density (kg/m³). Qinglong uses 2450kg/m³ as the standard calculation value to ensure data accuracy.

II. Weight Differences of UHPC Panels in Common Thicknesses The weight differences of UHPC panels of different thicknesses are significant and increase linearly: 20mm thick UHPC panels weigh approximately 49kg/m², suitable for lightweight decorative components; 30mm thick panels weigh approximately 73.5kg/m², a common specification for curtain walls; 40mm thick panels weigh approximately 98kg/m², usable for roofs and floor slabs; 50mm thick panels weigh approximately 122.5kg/m², suitable for large landscape components and load-bearing locations. Taking a 1m² standard panel as an example, each 10mm increase in thickness adds approximately 24.5kg to the weight, a difference that requires careful consideration in large-area applications. In the Shanghai Astronomy Museum project, Qinglong used 40mm thick panels for a 3-meter-high UHPC sculpture, keeping the weight of each panel within a reasonable range and reducing installation difficulty.

III. Engineering Application Value of Weight Differences Weight differences provide flexible selection options for projects: lightweight thicknesses (20-30mm) can reduce the overall building load and cut keel and foundation costs. The Shenzhen Longhua Xiangshan Science and Technology Park used 25mm thick UHPC curtain wall panels, saving 30% in keel costs compared with 50mm thick panels; heavy thicknesses (40-50mm) offer higher strength and durability, suitable for large outdoor components and load-bearing scenarios. In the Panzhihua Third Front Construction project in Sichuan, Qinglong selected UHPC panels of different thicknesses ranging from 30-50mm according to the load requirements of different parts, meeting performance requirements while optimizing the overall load design. In addition, weight data serves as the core basis for selecting lifting equipment and formulating transportation plans.

The weight differences of UHPC panels of different thicknesses follow clear patterns, allowing precise selection based on project loads, installation conditions, and performance requirements. Qinglong Group provides comprehensive weight parameter references and selection recommendations to help projects achieve "performance matching + cost optimization". Choosing a manufacturer with data support and engineering experience is key to matching weight design with installation plans.
