Weight Differences of UHPC Panels of Different Thicknesses and Analysis of Influencing Factors

In the field of building materials, weight is often a key factor affecting design decisions, construction efficiency, and structural safety. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will analyze, from a professional perspective, the weight differences of UHPC panels of different thicknesses and their core influencing factors, providing a scientific selection reference for designers and owners.

### Linear Correlation Between UHPC Panel Thickness and Weight As a representative of new decorative building materials, UHPC (Ultra-High Performance Concrete) exhibits a significant positive correlation between weight and thickness. Under normal conditions, for every 10mm increase in thickness, the weight of a standard UHPC panel (density approx. 2400kg/m³) increases by about 24kg/m². For example, a 15mm-thick UHPC exterior wall panel weighs approximately 36kg/m², while a 30mm-thick component reaches 72kg/m²; this difference directly affects the load design of building structures and installation plans. During the detailed design phase, Qinglong Group uses BIM technology to simulate the impact of UHPC panels of different thicknesses on the overall structure, ensuring a balance between safety and economy.

### Hidden Influence of Material Formulation on UHPC Panel Weight Beyond thickness, material formulation is the core variable determining UHPC panel weight. As a national high-tech enterprise, Qinglong Group has leveraged 28 years of technical accumulation to develop a fiber reinforcement system and an optimized mineral admixture solution: while ensuring compressive strength (≥150MPa), by adjusting the steel fiber content (typically 3-5%) and the proportions of silica fume and ultra-fine mineral powder, the weight of UHPC panels of the same thickness can be reduced by 5-8%. Compared with conventional industry products, Qinglong UHPC panels at 30mm thickness can be kept within 68kg/m², a technical advantage that gives them significant competitiveness in scenarios such as large-span curtain walls and special-shaped components.

### Weight Reduction Practices Through Structural Design and Process Innovation Detailed design capability is the core advantage of Qinglong Group's full-chain services. Through topological optimization design and openwork texture techniques, precise weight control of UHPC panels can be achieved without reducing structural strength. Taking the Nanjing East Road Century Plaza renovation project as an example, the Qinglong team adopted parametrically designed light-transmitting UHPC panels; through internal honeycomb structure optimization, the weight of 25mm-thick panels was reduced to 45kg/m² while meeting light transmittance and impact resistance requirements, and the project won the Silver Award of the first UHPC Construction Engineering Innovation Award (AALBORG WHITE Cup).

### Multi-dimensional Impact of Weight Differences on Project Implementation The weight differences of UHPC panels of different thicknesses directly relate to construction efficiency and cost control. Lightweight UHPC panels (e.g., 15-20mm) can be installed using dry installation methods, with individual panels handled manually, greatly reducing dependence on lifting equipment; whereas thick panels (above 30mm) require specialized lifting tools and structural reinforcement, extending the construction period by about 20%. Qinglong Group's production base in Nanning, Guangxi is equipped with intelligent production lines that can customize UHPC components of 20-100mm thickness according to project requirements, and provides full-process services from detailed design to installation guidance, ensuring efficient delivery of products of different weight specifications.

As a participant in the formulation of industry standards for UHPC/GRC/GRG/GRP materials, Qinglong Group has always upheld the mission of "Creating Aesthetic Architecture," balancing the weight, performance, and cost of UHPC panels through material innovation and technical optimization. Whether for the curtain wall systems of landmark buildings or artistic components in landscape gardens, choosing UHPC products of the appropriate thickness not only enhances a building's aesthetic expression but also achieves the dual value of structural safety and green construction. In the future, Qinglong will continue to deepen its expertise in the field of new decorative materials, providing more competitive solutions for global clients.
