A method and apparatus for forming a concrete block, particularly but not exclusively a composite block with a reflective facia portion. The block is formed by a dry-cast technique, in which mixture for forming the block has a water/cement ratio less than or equal to 0.35, in combination with application of a compaction force so that the resultant block complies with compressive strength requirements set out in BS 6717: Part 1: 1993.
La présente invention concerne un procédé et un dispositif de mise en forme de blocs de béton, en l'occurrence un bloc de béton composite pourvu d'une partie formant une facette réfléchissante. Le bloc est réalisé selon un procédé de moulage à sec selon lequel le rapport eau/ciment du mélange utilisé pour faire le bloc de béton est inférieur ou égal à 0,35. En outre, le procédé nécessite l'application d'une force de compactage permettant au bloc obtenu d'être conforme aux spécifications de résistance à la rupture en compression définies par la norme BS 6717: 1<ère> partie de 1993.
