What Should Be Noted in UHPC Construction? Key Technical Points of Qinglong UHPC Construction

UHPC construction requires special attention to key aspects such as material proportioning, pouring techniques, and curing conditions. Based on Qinglong's extensive engineering practice, the following technical points requiring special attention have been summarized.

During the construction of the curved curtain wall at the Wuhan Han Show Theater, the Qinglong team found that temperature control is a key factor affecting construction quality. When the ambient temperature exceeds 30℃, the initial setting time of UHPC is shortened by 40%, severely affecting construction quality. To address this, the team developed a temperature-controlled mixing process, adding ice water to the mix to keep the discharge temperature below 20℃, thereby ensuring construction quality. This case shows that only by strictly controlling every detail can the final result be guaranteed.

Key Points for Mix Proportion Control

Mix proportions must be weighed precisely, with errors kept within 0.5%. Qinglong uses an automatic batching system to ensure mix proportion accuracy.

Mixing Process Control

Mixing time and sequence directly affect quality. Qinglong determines optimal process parameters through testing to ensure the uniformity of the mix.

Pouring Process Control

Pouring must be continuous to avoid cold joints. Layered pouring is adopted to control the thickness of each layer.

Construction quality lies in detail control. It is recommended to choose an experienced construction team to ensure project quality.
