Method of preparing a fibre- reinforced plate comprising a cementitious matrix having uniformly distributed therein synthetic mineral fibres, natural organic fibres or mixtures thereof, fibres and a fine material having an average particle size lower than that of the cement particles, removing excess water therefrom to form a moist sheet, combining several moist sheets to form a multilayered product and allowing said product to harden to form a plate. The presence of fine particles in the slurry prevents fine cement particles from being removed together with excess water and a plate product having improved strength is obtained. |
