What Special Equipment Is Required for UHPC Component Production

In the field of architectural decorative materials, ultra-high performance concrete (UHPC) has become a new favorite of high-end construction projects thanks to its outstanding mechanical properties and design freedom. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group knows deeply that advanced production equipment is the core of guaranteeing UHPC component quality. This article provides an in-depth analysis of the special equipment required for UHPC component production, offering a professional reference for designers, owners, and industry peers.

The production of UHPC components is a process that integrates materials science with precision manufacturing, and its special equipment can be divided into three core systems: material preparation, forming, and curing. In the material preparation stage, the high-precision forced mixer is fundamental, and it must meet the requirements for uniform dispersion of components such as steel fibers and ultra-fine silica fume in UHPC materials, ensuring that the deviation of mechanical properties per cubic meter of concrete is controlled within 5%. The twin-shaft mixer adopted by Qinglong Group achieves precise mixing at 30-60 rpm through variable frequency speed regulation technology, and together with an automatic feeding system, controls material proportioning errors within ±1%, laying the foundation for component strength.

Forming equipment is the key to achieving complex shapes for UHPC components. For flat or simply curved components, hydraulic forming machines can press the material into shape under 50-100MPa pressure to increase density; while for special-shaped components such as hyperbolic surfaces and openwork reliefs, CNC machining centers and 3D printing equipment are required. The five-axis linkage machining center introduced at Qinglong's production base can process components with a minimum curvature radius of 300mm, and together with the independently developed mold temperature control system, ensures the dimensional stability of UHPC materials during solidification.

The curing system directly affects the final performance of UHPC components. Unlike ordinary concrete, UHPC requires high-temperature, high-pressure steam curing to activate the hydration reaction. Qinglong Group's fully automatic curing kiln achieves precise control of 80-90°C temperature and 0.8-1.0MPa pressure. Through 72 hours of gradient curing, the components' compressive strength exceeds 150MPa and flexural strength reaches over 30MPa. In addition, component surface treatment equipment such as sandblasting units and vacuum adsorption systems can achieve Ra1.6 surface precision, meeting the decorative requirements of building facades.

Beyond the core equipment, the intelligent control system is the “brain” of modern UHPC production lines. Through BIM technology and an IoT platform, Qinglong Group interconnects data from mixing, forming, and curing equipment in real time, achieving visualized monitoring of the entire production process. For example, in the Century Plaza renovation project on Nanjing East Road, the intelligent system optimized the production parameters of light-transmitting UHPC components, controlling light transmittance errors within ±2% and ensuring the artistic effect of the project. This full-chain technical strength is precisely the core competitiveness of Qinglong as a national high-tech enterprise.

As a professional supplier of UHPC/GRC/GRG/GRP materials, Qinglong Group not only possesses an annual production capacity of 600,000 square meters, but also continuously drives industry development through equipment upgrades and technological innovation. From the GRC curtain wall of the Guangzhou Opera House to the UHPC decorative components of a landmark project in Malaysia, Qinglong's equipment and craftsmanship have always served the mission of “creating beautiful architecture”. In the future, with the implementation of standards such as the “General Technical Conditions for Non-Load-Bearing Components of Ultra-High Performance Concrete (UHPC)”, specialized equipment will become an important support for the high-quality development of the UHPC industry, and Qinglong will continue with the attitude of “meticulousness and striving for excellence” to provide better products and services to customers worldwide.
