Abstract
The present invention relates to a fibrous construct which is used in providing cementitious mixtures supplemental and reinforcing strength upon setting, and more particularly, to a unitized fibrous construct which comprises a plurality of oriented reinforcing fibrous components, wherein the fibrous components can be cut to a predetermined and finite cut length upon formation and remain in a plural parallel form until such point the unitized fibrous substrate is incorporated and subjected to mechanical agitation during preparation of a cementitious blend or mixture.

A cementitious reinforcement comprising unitized fibrous constructs, each of said unitized fibrous constructs being comprised of two or more reinforcing fibrous components and one or more circumferential retaining elements, wherein said reinforcing fibrous components are combined in an essentially parallel orientation and said circumferential retaining element extends spirally and circumscribes about an over all circumference described by said combined and essentially parallel reinforcing fibrous components, said circumferential retaining element circumscribing no more than 80% of the total circumferential surface area of said unitized fibrous constructs.
