<p>A process for the preparation of an aqueous slurry of solids content at least 30% by weight, whose predominant solids content is a hydraulic cement and which contains synthetic inorganic reinforcing fibres to reinforce the cement when cured, said process comprising mixing with water a felt comprising organic web- forming fibre and said synthetic inorganic fibre, to form an aqueous dispersion of mixed fibres which contains said organic web-forming fibres in an amount forming at least 1% by weight of the water present, and thereafter adding the hydraulic cement to the dispersion of mixed organic and inorganic fibres to produce a slurry of cement content at least 15% by weight. Incorporating the ingredients according to this procedure reduces bailing up of the synthetic inorganic fibres and so improves the properties of composite articles made by compression- moulding the slurry.</p> |
