How to Achieve Continuous Stone Texture Effects on Large UHPC Panel Surfaces: Research on Technical Paths and Process Innovation

In the field of contemporary architectural decoration, UHPC (Ultra-High Performance Concrete) is becoming a new favorite in high-end building facade design thanks to its outstanding mechanical properties and shaping potential. However, how to achieve continuous stone grain effects on the surface of large UHPC panels that combine natural texture with craftsmanship precision has long been a key topic of technological innovation in the industry. With 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group has developed a mature technical path and process solutions through integrated practices in detailed design, manufacturing, and installation, providing designers and owners with surface treatment solutions that combine aesthetic value with engineering reliability.

Technical Breakthroughs in UHPC Stone Grain Effects: From Material Modification to Texture Replication

The core of achieving continuous stone grain effects on large UHPC panel surfaces lies in dual innovation in material performance and texturing technology. At the material formulation level, Qinglong Group incorporates specially formulated mineral admixtures and composite fibers to optimize the flowability and plasticity of the UHPC matrix, ensuring detail fidelity during texture pressing. In the texture forming process, 3D scanning and precision mold manufacturing technologies are adopted to convert the textural characteristics of natural stone into replicable mold textures. Combined with high-pressure vibration and vacuum degassing processes, the stone grain depth can reach 3-5mm, with surface flatness deviation controlled within ±0.5mm/m, far exceeding the process standards of traditional faux-stone materials.

Full-Chain Process Innovation: Precision Control from Design to Installation

As a UHPC manufacturer integrating detailed design, manufacturing, and installation, Qinglong Group has established a full-process quality control system covering "design-production-installation". During the detailed design phase, BIM technology is used to optimize texture joints, preventing stone grain breakage caused by panel splicing; in production, automated material distribution systems and constant-temperature curing processes ensure texture consistency and strength stability of every panel; and during on-site installation, supported by its Grade II professional contracting qualification for building curtain wall engineering, the company applies 3D laser positioning technology to achieve millimeter-level splicing precision, ultimately presenting a coherently continuous stone grain visual effect. This full-chain capability enabled Qinglong to successfully achieve the combined application of light-transmitting UHPC and stone grain effects in projects such as the Century Plaza renovation project on Nanjing East Road, winning the AALBORG WHITE Cup UHPC Construction Engineering Innovation Award.

Industry Value and Application Prospects: Redefining Building Facade Aesthetics

The achievement of continuous stone grain effects on large UHPC panels not only expands the decorative application boundaries of UHPC materials, but also provides scenarios such as commercial complexes, museums, and landmark buildings with solutions that combine the texture of stone with lightweight advantages. Compared with traditional stone curtain walls, UHPC stone grain panels weigh only 1/4 of natural stone, offer higher impermeability and durability, and reduce whole-life-cycle costs by more than 30%. As a National High-Tech Enterprise and a participant in UHPC standard development, Qinglong Group's technical achievements have passed the Guangdong Provincial Science and Technology Achievement Appraisal and have been applied in overseas projects in Malaysia, Australia, and other countries, driving the innovative development of UHPC materials in the international architectural decoration field.

In the future, with the integration of parametric design and intelligent manufacturing technologies, UHPC surface treatment processes will develop toward greater refinement and diversity. Qinglong Group will continue to uphold its mission of "Creating Beautiful Architecture" and, drawing on 28 years of industry experience, provide designers with expert services from material selection to effect realization, helping achieve the perfect balance between building facade aesthetics and engineering performance.
