How to Evaluate UHPC Product Cost-Effectiveness?

In the field of modern architectural decoration, GRC (Glass Fiber Reinforced Concrete), with its lightweight high strength and flexible shaping characteristics, has become an ideal choice for high-end projects such as grand theaters, commercial complexes, and landmark buildings. As an industry leader with 28 years of full-chain experience in UHPC/GRC/GRG/GRP materials, Qinglong Group will comprehensively analyze the production secrets of GRC—from material properties and production processes to quality control—providing a professional reference for designers and owners.

The core of the GRC production process lies in the precise control of material proportions and molding technology. Its main raw materials include high-strength cement, alkali-resistant glass fiber, fine aggregate, and additives, among which the proportion of glass fiber directly affects the flexural strength of the product (premium GRC can reach over 20MPa). Through 28 years of technical accumulation, Qinglong has developed a unique formulation that ensures material lightweighting (weighing only 1/4 of traditional stone) while meeting the structural stability requirements of complex shapes. In the mixing stage, a planetary mixer is used to achieve uniform dispersion of fibers and matrix materials, avoiding the strength loss caused by fiber agglomeration in traditional processes.

Mold design and fabrication is a key step in GRC production, directly determining product precision and surface texture. Using BIM technology and parametric design software (such as Rhino and Grasshopper), Qinglong can achieve complex shapes such as hyperbolic surfaces and openwork reliefs with a minimum radius of curvature of ≤300mm. Mold materials are selected as GRP (fiberglass) or silicone according to project requirements, with silicone molds particularly suitable for European classical components with fine textures (such as Roman columns and cornices). The production base is equipped with automated production lines with an annual capacity of 600,000 square meters, and three-dimensional scanning positioning technology ensures that errors in mold reuse are controlled within ±1mm.

Molding and curing processes directly affect the durability of GRC components. Qinglong adopts a process combining spray-up molding and premix casting: spray-up molding is suitable for thin-walled components, in which fibers and mortar are uniformly attached to the mold through a high-pressure spray gun; premix casting is used for large load-bearing components to ensure concrete compactness. The curing stage combines steam curing with natural curing, promoting the hydration reaction in a constant temperature and humidity environment, so that the product achieves a 28-day compressive strength of over 80MPa. It is worth noting that the "Technical Standard for Building Application of Glass Fiber Reinforced Cement (GRC)" (JGJ/T423-2018), which Qinglong participated in formulating, clearly specifies curing cycles and environmental parameters, becoming a benchmark for industry quality.

Quality inspection and full-process control are the last line of defense in GRC production. Each batch of products must undergo more than 20 indicator tests including flexural strength, elastic modulus, and frost resistance, among which the weather resistance test simulates extreme environmental cycles from -40℃ to 70℃ to ensure stability under different regional climate conditions. As a national high-tech enterprise, Qinglong has established a comprehensive quality traceability system, recording full life-cycle data from raw materials to installation through RFID chips. In terms of project cases, the GRC curtain wall project of the Dongguan Women and Children's Activity Center won the Silver Award of the First GRC Building Engineering Innovation Award for its zero-error installation and outstanding durability.

From material R&D to project implementation, every step of the GRC production process embodies technical accumulation and professional craftsmanship. With the mission of "creating beautiful architecture," Qinglong Group perfectly combines the artistic expressiveness of GRC with structural safety through full-chain services covering detailed design, manufacturing, construction and installation, and after-sales maintenance. Whether it is the minimalist curtain wall of modern buildings or the decorative moldings of classical style, GRC, with its unique advantages, has become an important vehicle for architectural designers to realize their creativity, driving the innovative development of the architectural decoration industry.
