ABSTRACT:
A process for the production of concrete roofing products of reduced weight loading having a thickness in section of not greater than 15 mm. The process involves forming an asbestos-free cementitious composition comprising (i) lightweight aggregate, (ii) hydraulic cement, (iii) water and (iv) reinforcing fibers in an amount of not more than 4% by weight of the total weight of the composition but the fibers being present in an amount sufficient to provide a reinforcing effect and impact strength in the roofing product, the cementitious composition being capable of being shaped by a roller and slipper method, and thereafter shaping the cementitious composition by the method to provide a shaped extrudate, dividing the extrudate to form sections and curing the sections to provide roofing products, wherein the reinforcing fibers have lengths of 0.5 mm to 20 mm. The impact resistant roofing products are useful as roofing tiles, or a replacement for shingles, shakes and slates.
