What Should Be Paid Attention to in UHPC Construction? Key Technical Points of UHPC Construction

UHPC construction requires special attention to key aspects such as material preparation, pouring techniques, and curing regimes. Based on 28 years of construction experience, Qinglong has summarized the following key technical points.

In the Nanning New Media Center project, strict implementation of construction points ensured project quality. The project adopted an electronic batching system to ensure accurate mix proportions; used specialized mixing equipment to ensure even fiber distribution; employed a layered pouring technique to avoid defects; and implemented precise temperature-controlled curing to guarantee strength development. Strict execution of these technical points earned the project a major industry quality award.

Mix Proportion Control Points

Raw material measurement accuracy must be within 0.5%. Fiber addition must follow process requirements. Mixing time must be adjusted according to equipment performance.

Pouring Technique Points

Pouring speed must be uniform to avoid segregation. Vibration must be moderate to avoid over-vibration or missed spots. Complex areas require special pouring measures.

Curing Regime Points

Curing must begin promptly after final setting to prevent plastic cracks. Temperature control must be precise to avoid thermal stress. Curing time must be sufficient to ensure strength development.

Quality Monitoring Points

Every process step must be strictly inspected; work may not proceed to the next step if the previous step fails inspection. Specimen preparation must be standardized, and data records must be complete.

Strict implementation of technical points is the key to ensuring UHPC construction quality.
