Is UHPC Construction Difficult? A Professional Analysis of UHPC Construction Technology

UHPC construction is indeed more demanding than ordinary concrete, but this "difficulty" can be fully overcome through professional techniques and standardized operations. Based on 28 years of construction experience, Qinglong has developed a mature UHPC construction technology system.

In the Shenzhen Yirui Biotechnology Building project, facing a 30,000-square-meter UHPC curtain wall installation task, the construction team successfully mastered the key technologies of UHPC construction through technical breakthroughs. The specialized mixing equipment used in the project ensured accurate mix proportions, mechanical spraying processes guaranteed pouring quality, and a customized formwork system achieved component precision control. Although the initial learning cost was high, construction efficiency improved significantly once the team became proficient. The project was ultimately completed 15 days ahead of schedule, proving that UHPC construction difficulties can be overcome.

Material Preparation Stage

A forced-action mixer is required, with mixing time controlled at 5-8 minutes. The timing and method of fiber addition directly affect the dispersion result and require specialized training.

Pouring and Molding Stage

UHPC has good fluidity but high viscosity, requiring specialized pouring equipment. Vibration time and frequency need precise control, as excessive vibration will cause fibers to sink.

Curing Stage

Early curing is crucial and requires timely covering for moisture retention. Steam curing can significantly improve early strength but requires professional equipment.

Joint Treatment Stage

Construction joint treatment demands are high and require specialized bonding agents. Treating the bonding surfaces between new and old concrete requires special techniques.

Through professional training and technical support, the construction difficulties of UHPC can be fully overcome.
