Abstract (en)

The need for curing moulds in the manufacture of concrete roof tiles becomes possible in a process which overcomes the problem of handling thin, non-planar, uncured (and necessarily wet) tiles and which comprises the steps of metering concrete mix into a tile mould, applying pressure to the mix in the mould both to form an uncured tile having a thin, non-planar shape which nevertheless permits packing of the tiles to form a substantially solid block of tiles, and also to dewater and deaerate the mix and give an uncured tile containing the water required for hydraulic curing, removing the uncured tile from the mould, and loading the tile into a support frame - the steps being repeated, and the loading being carried out with the repitition of the steps, so as to form a virtually solid block of uncured tiles on the support frame; and curing the tiles or allowing the tiles to cure, while in the form of the solid block.
