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.
Claims19
A cementitious reinforcement comprising at least one unitized fibrous construct comprised of two or more reinforcing fibrous components and one or more circumferential retaining elements, wherein said one or more circumferential retaining elements combine said reinforcing fibrous components in an essentially parallel orientation as a single group of said reinforcing fibrous components and said one or more circumferential retaining elements extend spirally and circumscribe about an overall circumference defined by said single group of combined and essentially parallel reinforcing fibrous components, wherein said construct having an overall length and a total circumferential surface area being defined as the overall length and the overall circumference of said construct, and no more than 80% of the total circumferential surface area of said unitized fibrous construct being circumscribed by circumferential retaining elements.
A cementitious reinforcement comprising at least one unitized fibrous construct comprised of two or more reinforcing fibrous components and an interlocking means for combining said reinforcing fibrous components of said unitized fibrous construct into a single group of said reinforcing fibrous components, wherein said interlocking means combines said reinforcing fibrous components in an essentially parallel orientation as a single group of said reinforcing fibrous components and said interlocking means is applied about an overall circumference defined by said single group of combined and essentially parallel reinforcing fibrous components, wherein said construct having an overall length and a total circumferential surface area being defined as the overall length and the overall circumference of said construct, and no more than 80% of the total circumferential surface area of said unitized fibrous construct being circumscribed by interlocking means.
A cementitious reinforcement comprising at least one unitized fibrous construct comprised of two or more reinforcing fibrous components and one or more circumferential retaining elements, wherein said one or more circumferential retaining elements combine said reinforcing fibrous components in an essentially parallel orientation and said one or more circumferential retaining elements extend spirally and circumscribe about an overall circumference defined by said combined and essentially parallel reinforcing fibrous components, wherein said construct having an overall length and a total circumferential surface area being defined as the overall length and the overall circumference of said construct, and no more than 30% of the total circumferential surface area of said unitized fibrous construct being circumscribed by circumferential retaining elements.
