Abstract

A method of moulding articles from a concrete mixture. As shown in Fig 1, the water (12) is first poured into the mould (14, 14'), whereafter the dry cement mixture (2) is poured into the mould, soaking up the water. Another form of the invention is shown in Fig 2, where instead of pouring the water into the mould, the cement mixture (2) is moistened by water (1) sprayed into the dry mixture just before the mixture is poured into the mould. The invention is especially advantageous when mixtures containing fibres are used or when the articles are formed by centrifugal moulding.
