Method for casting a concrete, which can be used in making manufactured products intended for the building industry and containing a filler composed partly of petrified hemp stalk (boon) aggregates, characterised in that, during moulding, the concrete is compressed between at least two opposite walls of the mould, exerting antagonistic pressures on these walls, which produces a density which decreases towards the centre of the product when extracted from the mould, thus increasing its thermal and acoustic insulation power. The invention provides a solution to the problem posed by implementing concrete containing at least partly light granulates of vegetable origin, of a novel type, which the petrified hemp stalk (boon) aggregates are. It provides a novel and innovative technology in the field of civil engineering. <IMAGE>
