Estimation of Super High-Rise Pumping Pressure for High-Performance

The actual concrete pumping process is shown in Figure 1. Concrete flows through the pipe line under pressure action supplied by the pump. According to the fluid mechanism, the inlet is taken as velocity type where the value is determined by the actual flow rate. Meanwhile, the outlet is set as pressure type where the velocity is zero.

Mix design and fresh properties for high-performance

The printing process is in three stages: data preparation, concrete preparation, and component printing. In the data preparation stage a component is designed as a 3D CAD model, then converted to an STL file format and sliced with a desired layer depth. The printing path for each layer is then generated to create a G-Code file for printing.

Concrete Pumping How to Pump Cement Concrete Network

Concrete being pumped through a line experiences friction with the internal wall of the pipeline. The longer the line, the more friction encountered. For longer pumping distances, the use of smooth-walled steel pipe can lower the resistance. The length of hose used at the end of the pipeline adds to the overall line length as well.
