Is UHPC Construction Difficult? Key Technical Points and Qinglong Group's Professional Empowerment System

Compared with ordinary concrete, UHPC construction places higher demands on "mix proportion precision, mixing process, forming methods, and curing conditions," presenting a certain technical threshold—but not an insurmountable one. Its "difficulty" mainly lies in the process particularities arising from material characteristics. Through 28 years of practice, Qinglong Group has developed a construction solution of "customized materials, specialized equipment, skilled crews, and refined management," packaging complex technology into standard operating procedures and providing full-process technical support to keep construction difficulty under control. During construction of the super-large roof at the Hainan Convention and Exhibition Center, we deployed an expert team and customized special equipment, successfully completing the installation of 120,000 square meters of double-curved panels with a first-pass acceptance rate of 99.5%. Professional preparation is the key to overcoming difficulty.

Mix Proportion Design and Mixing Control Are the Primary Challenges

UHPC has an extremely low water-binder ratio (0.18-0.22) and high viscosity, requiring forced-action mixers and high-performance water reducers. Mixing time and feeding sequence must strictly follow the mix proportions. Qinglong provides precast dry-mix materials or on-site mixing guidance to ensure workability. Automatic mixing plants enable precise control and avoid manual errors.

Forming Process Selection and High Operating Requirements

Spraying or casting processes are selected based on component shape. Spraying requires professional robotic equipment, while casting requires high-frequency vibration. Qinglong prefabricates main components in the factory, with only installation performed on site, reducing on-site work difficulty. For complex-shaped components, we provide installation method guidance, such as the hoisting plan for the special-shaped panels of the Wuhan Han Show Theater.

Curing Is Critical and Easily Overlooked

UHPC requires timely temperature- and moisture-retaining curing to prevent cracking. Steam curing can accelerate strength development. We formulate detailed curing plans and provide curing agents or recommend covering measures. Neglecting curing leads to insufficient strength and surface defects.

Professional Team and Coordinated Management Are Key

Construction personnel must be trained to understand material characteristics. Qinglong provides technical briefings and on-site demonstrations, and can dispatch engineers for on-site guidance. BIM technology simulates construction in advance to avoid clashes. Professional management can effectively reduce difficulty.

In summary, UHPC construction difficulties can be overcome by choosing a professional manufacturer and thorough preparation. Qinglong Group's full-process service lets customers "use it with peace of mind."
