A particular advantage of the centrifugal (spinning) process is the production of longitudinally pre-stressed concrete products, such as posts, poles and pressure pipes. During the centrifugal process, the mould with the fresh concrete is set into rotation. This affects on the concrete mass a centrifugal force, which presses the concrete outward to the mould wall. This delivers a typical grain structure of a concrete texture with outmost density and minimum pore volume.
The advantages of the Centrifugal method:
- Higher density through a very high concrete compaction
- Closed smooth surfaces of the products
- Exact length and outer diameter by full mould space
- Suitable for the production of longitudinally pre-stressed concrete products with excellent structural qualities
The perfect solution for the
production of dry-cast concrete
Vibro-Compaction and Pressing method
PRINZING PFEIFFER was significantly involved in the development of the vibro-compaction and pressing method for the concrete precast concrete industry.
