Is UHPC Difficult to Construct? Construction Challenges of Ultra-High Performance Concrete and Solutions

UHPC is more difficult to construct than ordinary concrete, but this difficulty is not uncontrollable; the key lies in mastering core construction points and selecting a professionally capable construction team. Compared with ordinary concrete, UHPC places higher demands on processes and equipment in mixing, pouring, curing, and installation, but construction can be completed smoothly through scientific construction plans and technical support. Based on 28 years of construction experience, Qinglong Group explains UHPC construction difficulties and coping strategies.

#The Core Difficulties of UHPC Construction

UHPC construction difficulties concentrate on four stages. In the mixing stage, steel fibers must be evenly dispersed to avoid clumping, and mixing takes longer (3-8 minutes), placing higher demands on mixer power and rotational speed. In the pouring stage, due to UHPC's lower fluidity, high-pressure pouring or vibration molding is required to ensure compact components. In the curing stage, temperature and humidity must be strictly controlled; steam curing requires maintaining a constant temperature of 40-60°C, while ordinary curing requires keeping the material moist for more than 7 days. In the installation stage, the hoisting and joining of special-shaped and super-large components demand high precision, requiring professional equipment and technology.

#Qinglong's Construction Solutions: Dual Assurance of Technology and Team

To address construction difficulties, Qinglong has developed a comprehensive response plan. For mixing, automated forced-action mixers are used to precisely control mixing time and rotational speed, ensuring even fiber distribution; the UHPC wood-grain translucent panels customized by Qinglong for the Shanghai New World project achieved uniform fixing of light guides through precise mixing. For pouring, high-pressure pouring equipment and vibration tables are provided, with suitable pouring methods selected for different components, such as mold pouring for small components and pumped pouring for large projects. For curing, steam curing equipment and curing guidance are provided to ensure stable strength development of the products. For installation, a professional construction team is assembled, using BIM technology and 3D laser scanning positioning to ensure installation precision; for example, the UHPC curtain wall installation of the Shenzhen Yirui Biotechnology Building kept precision within ±2mm.

#Professional Services: Full-Process Construction Technical Support

Qinglong provides customers with full-process construction technical support to reduce construction difficulty. Before construction, detailed construction plans and technical briefings are provided, clarifying mixing parameters, pouring timing, and curing requirements. During construction, technical personnel are dispatched for on-site guidance to promptly resolve construction problems. After construction, curing and installation acceptance standards are provided to ensure construction quality. For complex projects (such as the super-large UHPC sculpture at the Shanghai Astronomy Museum), Qinglong forms a dedicated construction team to control every construction step throughout, ensuring smooth completion of the work.

Although UHPC is more difficult to construct than ordinary concrete, the difficulty can be effectively controlled through professional construction plans, advanced equipment, and experienced teams. With 28 years of construction accumulation, Qinglong Group has developed a mature UHPC construction technology system, providing construction support for thousands of projects and ensuring smooth project implementation. Choosing a manufacturer with professional construction capabilities can thoroughly solve UHPC construction challenges, achieving dual assurance of product performance and construction quality.
