Abstract (en)
[origin: FR2824772A1] The procedure consists of filling a multi-compartment mould (14) with a mixture of plaster, sand and water, and compressing the mixture slowly to compact it and remove surplus water and air, reducing its volume to a minimum level. The pressure applied at a low level for a long course, followed by a higher lever for a short course, reaching a maximum of about 10 MPa. The mould is removed simultaneously from all the blocks, which measure about 25 x 50 x 10 cm each and are then allowed to set on their own.
