What Are the UHPC Casting Methods? A Complete Guide to Qinglong's UHPC Casting Process

The casting method of UHPC directly affects molding quality and performance. Through 28 years of practice, Qinglong has developed various mature processes including conventional casting, pump casting, and spray casting, allowing the most suitable method to be selected according to project needs.

In the hyperbolic curtain wall project of Nanning New Media Center, facing complex shaping requirements, Qinglong innovatively adopted the self-leveling casting method. By optimizing the mix proportion, the flowability of the mixture reached over 700mm while keeping the viscosity coefficient within a reasonable range. This high-flow concrete automatically fills every corner of the mold without vibration, perfectly reproducing the design shape. Project testing showed that the components had uniform density, with the standard deviation of strength controlled within 3%, achieving ideal results.

Applicable Conditions for Conventional Casting

Suitable for regularly shaped components. Requires moderate vibration to remove air bubbles. Control the casting speed to avoid segregation.

Key Points of Pump Casting Technology

The mix proportion needs to be optimized to ensure pumpability. When the pumping distance exceeds 100 meters, special mix design is required.

Advantages of the Spraying Process

Suitable for complex curved surface construction. Fibers are distributed in an oriented manner for better reinforcement. Requires professional equipment and technology.

Choosing the right casting method is crucial. It is recommended to select the optimal process based on component characteristics.
