Abstract
A manufacturing process produces an article in slab form and more precisely an article made from a hydrated matrix which contains cement, sand, water and reinforcing fibers. The process includes the steps of mixing the constituents until a substantially homogeneous mineral paste is obtained; extruding the mineral paste in the form of a sheet having a thickness approximately equal to that of the article; and cutting the sheet to the size of the article. The article is made in the form of a slab and may be an imitative slate piece to be used as a roofing cover element.
