Abstract

In a method for making vessels from cement open at least at one end, for instance from cement mortar and a reinforcement which is added to the cement while it is wet, the mixture being introduced into a mould from which the vessel is removed with an outer wall having the smoothness of the formwork, provision is made according to the invention for glass fibres to be used as the reinforcement and added to the wet cement delivered under pressure in a free spray (50) as it is delivered, and for the mould (42) to be rotated upon itself on a plate (43) about a vessel axis passing essentially perpendicularly through the aperture area of the vessel, the mixture being introduced through the vessel aperture and the free spray (50) being swivelled and/or moved downwards in a perpendicular plane of the vessel in order to apply the mixture to the mould wall in layer upon layer of wet cement, whereupon the vessel is removed from the formwork as a self- supporting body. <IMAGE>
