ABSTRACT:
A cementitious product and production method wherein the product comprises cement with reinforcing glass fibres therein which are coated with a composition which consists essentially of a protective material to reduce deterioration of the glass fibres, the material being a monocyclic or polycyclic aromatic compound which has at least three hydroxyl groups on the aromatic ring, or when a polycyclic compound is employed, on at least one of the aromatic rings. Preferably, the aromatic compound is soluble in a calcium hydroxide solution, and a preferred such compound is pyrogallol. The composition can also contain a film-forming agent such as a polyvinyl acetate of cationic character or a polyethylene glycol of non-ionic character, as well as a linking agent such as a silane.
