Abstract
Shaped articles of hydraulic cement compositions reinforced with fiber glass fabric or with chopped fiber glass, and having a smooth, reflective surface, are produced by the admixture of 'super' water reducers to the aqueous cementitious slurries followed by casting or spraying into synthetic polymer molds, or molds coated with such synthetic polymers which are water repellent and non-sticking to hydraulic cements, to yield cured articles of high flexural strength with at least one surface which is an exact reproduction of the surface of the synthetic polymer mold, such as high gloss and patterned design. A great variety of useful articles may be produced, such as building panels, curtain walls, hollow utility poles and pipes, 'raised' flooring panels, roofing tiles, protective barriers, and other products requiring thin shell, high flexural strength products for decorative and utilitarian uses.
