Abstract
The present disclosure relates to cementitious articles that are reinforced with a fabric made at least partially of high modulus polyolefin monofilament fibers. Preferably, the polypropylene monofilament yarns have a 3% secant modulus of elasticity of at least 100 g/denier. The high modulus polypropylene fabric has an intrinsic resistance to the alkaline conditions present in a cementitious composite, as well as a low elongation at break. The high modulus polypropylene may contain a nucleating agent to facilitate the process of obtaining desired draw ratio.
