Abstract

1,204,541. Moulding glass fibre reinforced plaster. NATIONAL RESEARCH DEVELOPMENT CORP. 1 Feb., 1968 [1 Feb., 1967], No. 4962/67. Heading B5A. Reinforced plaster articles are made by mixing glass fibres with an aqueous slurry of gypsum plaster, transferring the mixture to a mould and removing water to lower the water/plaster ratio to a value approaching but not below the minimum required to hydrate the plaster. The glass fibre may be in the form of a mat which is impregnated with plaster slurry, and several such mats may be stacked together in the mould. Excess water may be removed by centrifuging, suction of about 12 lb./sq. in. or a pressure of about 400 lb./sq. in. The aqueous plaster slurry preferably contains 50 parts by weight of water to 100 parts by weight of plaster and the glass fibre comprises up to 15 wt. per cent of the reinforced article.
