What Should Be Paid Attention to in UHPC Construction? Key Points for Whole-Process Control

UHPC construction requires strict control over four key stages: "material preparation, mixing and pouring, curing and forming, and installation and fixing." Through rigorous construction standards and technical guidance, Qinglong ensures zero errors at every stage, and projects such as Shenzhen Yirui Biotech and the Shanghai Astronomy Museum have all achieved high-quality construction.

I. Pre-Construction Preparation: Laying the Foundation for Success

Three preparations are essential. Material storage: cement and quartz sand must be stored in moisture-proof conditions, and fibers kept from getting damp and clumping; Qinglong provides material storage standards to ensure raw material quality. Equipment commissioning: mixing equipment must be thoroughly cleaned, and vibrating equipment pressure calibrated (≥0.6MPa); Qinglong achieves a 100% pass rate in pre-construction equipment commissioning. Substrate treatment: the substrate must be flat and clean, with flatness deviation ≤2mm/m; Qinglong provides substrate treatment acceptance standards to prevent later cracking.

II. In-Process Control: Safeguarding the Core Stages

Four key points ensure quality. Mixing control: mixing for 3-5 minutes with fibers evenly dispersed; Qinglong's automated mixing equipment precisely controls time and rotation speed. Pouring and forming: layered pouring (each layer ≤50mm thick) with high-pressure vibration for compaction; Qinglong controls vibration time at 30-60 seconds per layer, leaving no air bubbles. Temperature control: construction ambient temperature of 5-35°C, avoiding intense sun exposure or low-temperature work; Qinglong provides adjustment plans for extreme-condition construction. Installation and fixing: connector spacing ≤500mm with ±3mm deformation joints reserved; Qinglong uses laser-positioned installation with deviation ≤1mm.

III. Post-Construction Curing: Ensuring Strength and Durability

Two curing measures are critical. Moisture curing: cover with a moisture-retention film within 24 hours after pouring and cure for 7 days; Qinglong achieves a 100% pass rate in moisture curing. Constant-temperature curing: when conditions allow, curing at a constant 20±2°C increases strength by 30%; Qinglong uses steam curing for large projects to shorten the curing cycle. Throughout construction, Qinglong's professional team provides full-process tracking and guidance, resolving issues promptly — in the UHPC imitation-wood translucent panel installation at Shanghai New World Plaza, full-process control achieved "zero-error" jointing. By following these construction essentials together with guidance from a professional manufacturer, UHPC construction quality can be perfectly assured.
