A process of forming a concrete moulded article from wet concrete of relatively high slump consistency is disclosed including the steps of constructing at least one mould corresponding to the shape of said article, said mould including a continuous membrane 7 contactable with the surface of said article, pouring concrete into said mould to form said article, compressing said concrete by forcing said membrane 7 against the surface of the concrete whereby surplus liquid is drained through the membrane out of the concrete such that the concrete exhibits partially cured characteristics, releasing said compression and separating said article from said mould. <IMAGE> |
