What Are the Casting Methods for UHPC? A Comprehensive Analysis of UHPC Casting Technology

The pouring method for UHPC must be selected based on component shape, dimensions, and construction conditions. Common methods include manual pouring, pump pouring, and spray pouring. Based on engineering practice, Qinglong has summarized the applicable conditions and technical key points of various pouring methods.

In the construction of the complex curved surface structures of the Wuhan Hanxiu Theater, a combined scheme of multiple pouring methods was adopted. Pump pouring was used for flat sections to ensure efficiency; manual pouring was used for curved sections to ensure quality; spray pouring was used for special sections to solve construction challenges. This comprehensive scheme both ensured construction quality and improved work efficiency, and the project received praise from all parties.

Manual Pouring Method

Suitable for small-batch, complex-shaped components. Operators must be trained and operate according to process requirements. Advantages: good flexibility; disadvantages: low efficiency.

Pump Pouring Method

Suitable for large-scale, conventional-shaped construction. Specialized pumping equipment suitable for UHPC must be selected. Advantages: high efficiency; disadvantages: high equipment requirements.

Spray Pouring Method

Suitable for complex curved surfaces and thin-walled structures. Requires professional equipment and operators. Advantages: strong adaptability; disadvantages: relatively high cost.

Self-leveling Pouring Method

Suitable for large-area construction of horizontal components. The mix must have excellent flowability. Advantages: good surface quality; disadvantages: high requirements for mix proportions.

Selecting an appropriate pouring method according to specific project conditions is very important.
