Flexible fibers, cementitious mixtures comprising flexible fibers, and building components formed therefrom

Abstract

Flexible fibers, along with cementitious mixtures and building materials formed therefrom, are disclosed. In one aspect, a flexible fiber comprises a polymeric component and an inorganic component. In some embodiments, the surface of the flexible fiber comprises exposed pores. In some cases, at least some of the inorganic component is exposed on the surface of the flexible fiber. In some implementations, the polymeric component comprises a polyolefin. In some instances, the polyolefin comprises a polypropylene homopolymer or copolymer. In some embodiments, a linear density of the flexible fiber is from 0.5 decitex (dtex) to 50 dtex. In some cases, the flexible fiber has a length between 2 mm and 40 mm. In some implementations, the flexible fiber further comprises a foaming agent. In some instances, the inorganic component comprises calcium carbonate, silicon dioxide, titanium dioxide, talc, or a combination of two or more of the foregoing.
