METHOD AND SYSTEM FOR FABRICATION OF ELONGATE CONCRETE ARTICLES

摘要

A method for fabricating an elongate concrete article including introducing a concrete mix having a relatively high water to cement ratio into a fabrication assembly, the fabrication assembly including a core assembly and an outer mould. The method then involves dewatering in a first stage the concrete mix as it is pumped into a mould cavity formed between the core assembly and the fabrication assembly to reduce the water to cement ratio and then dewatering in a second stage the concrete mix after the mould assembly has been filled to further reduce the water to cement ratio.
