Key Points to Note in UHPC Construction

In the field of architectural decorative materials, UHPC (Ultra-High Performance Concrete) is becoming the material of choice for high-end construction projects thanks to its outstanding mechanical properties and design expressiveness. However, the professionalism and complexity of its construction process are often the key to project success. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group draws on full-chain experience to explain the core points of UHPC construction, helping your project be delivered efficiently.

I. Material Property Control: The Fundamental Prerequisite for UHPC Construction

The unique properties of UHPC determine the special nature of its construction. Compared with ordinary concrete, UHPC offers ultra-high strength (compressive strength up to 150-200MPa), excellent durability, and good flowability. Before construction, special attention should be paid to material mix proportions and mixing techniques to ensure that fibers are evenly dispersed without agglomeration. Qinglong Group recommends using dedicated mixing equipment, strictly controlling the water-binder ratio and mixing time, and adjusting admixture dosage according to the ambient construction temperature to prevent fluctuations in material performance from affecting construction quality.

II. Formwork Engineering: Precision Determines Forming Quality

UHPC components typically feature complex shapes and high precision requirements, making the design and installation of the formwork system crucial. Formwork materials with high rigidity and good flatness (such as steel molds or high-density plastic molds) should be selected, together with modular assembly techniques. For special-shaped components such as double-curved surfaces and hollowed-out patterns, Qinglong Group achieves precise formwork positioning through BIM technology and 3D scanning, keeping geometric dimensional errors within ±2mm. In addition, formwork joints must be properly sealed to prevent slurry leakage that could cause surface defects.

III. Pouring and Curing: The Core Steps to Ensure Strength and Durability

UHPC pouring must follow the principle of "layered pouring and symmetric vibration" to avoid air bubbles or voids caused by pouring too quickly. High-frequency vibrators should be used during vibration to ensure concrete compactness. The curing stage requires strict control of temperature and humidity; steam curing or covered moisture-retention curing is recommended so that components reach over 90% of design strength within 7 days. Qinglong Group's production base in Nanning is equipped with an intelligent curing system, ensuring the mechanical properties of UHPC components remain stable through precise temperature control.

IV. Installation Techniques: A Dual Test of Safety and Precision

UHPC component installation must balance both safety and aesthetics. Qinglong Group adopts "3D laser scanning + modular installation" technology, building 3D models of components and installation references in advance to achieve millimeter-level installation accuracy. For large-span or high-altitude installation scenarios, special load calculations are required, high-strength connectors should be selected, and anti-corrosion treatment must be carried out. In addition, structural sealing and waterproofing treatment must be performed after installation to prevent rainwater penetration from affecting durability.

V. Full-Chain Service: Safeguarding from Design to Maintenance

High-quality UHPC construction cannot be achieved without full-process support. As a national high-tech enterprise offering full-chain services covering detailed design, manufacturing, construction and installation, and after-sales maintenance, Qinglong Group provides one-stop solutions—from scheme optimization and material selection in the early project stage, to technical guidance during construction, and further to later maintenance. For example, in the Century Plaza renovation project on Nanjing East Road, the Qinglong team successfully achieved a perfect combination of architectural aesthetics and practical functions through customized production and precise installation of translucent UHPC components.

UHPC construction is a comprehensive reflection of technology and experience, and precise control at every stage directly affects the final result. Backed by 28 years of industry experience, Qinglong Group will continue to provide designers and owners with professional and reliable UHPC solutions, helping create more architectural works that combine artistic value and engineering quality.
