Abstract
A method is provided for making a cement composite product such as a flat or profiled sheet, or a pipe, containing glass fibre as reinforcement instead of the traditional asbestos, wherein a cement and water slurry of flowable consistency is made with high shear agitation, the glass fibre is mixed with the slurry in a static mixing apparatus (i.e. having no moving parts) by bringing together flows of the slurry and of the glass fibre and then altering the path of the conjoined flow, and the glass fibre-containing mixture is immediately subjected to the conventional deposition on a water-permeable web, formation of a profile if desired, drainage of the water from the slurry through the web, and curing the deposited cement to form the product.
