Method of forming a reinforcing element
View Patent ↗A reinforcing element and a method of forming the reinforcing element are generally described. The reinforcing element may be used in reinforcing a cementitious material and may comprise a settable material and a tension-resistant material that extends for a length of the element. To form the reinforcing element the settable material and tension-resistant material may be disposed together such that the settable and tension-resistant materials generally take the form of the reinforcing element. The settable material may then be cured.
1. A method of forming a reinforcing element for use in reinforcing, a cementitious material, the method comprising:
disposing a flexible tension-resistant material, such that the flexible tension-resistant material has, or assumes, a tubular form and is made from a material formed from a plurality of one or more woven fibers or from a plurality of one or more metal wire strands woven together into the flexible tension-resistant material;
lining an internal circumference of the tubular form of the flexible tension-resistant material with another material, wherein the other material is resistant to penetration by a settable material including one of a curable cementitious material and a settable polymer, and wherein the other material is a latex-based polymer;
introducing the settable material under pressure into a discrete length of the flexible tension-resistant material by positioning the flexible tension-resistant material around a formed tubular length of the settable material; and
curing the settable material, such that the flexible tension-resistant material assumes a tubular form.
2. The method of claim 1 , further comprising: one of;
separating the discrete length of the flexible tension-resistant material is from a longer length of the flexible tension-resistant material, wherein another discrete length of the settable material is introduced into the discrete length of the flexible tension-resistant material; and
positioning the flexible tension-resistant material around an elongate hollow mandrel, wherein the discrete length of settable material is formed, when the settable material passes through the mandrel and into a tubular form of the flexible tension-resistant material.
3. The method of claim 1 , wherein the other material adds an additional layer internal to the tubular form of the flexible tension-resistant material.
4. The method of claim 1 , wherein, the other material is hydrophobic when the settable material comprises water.
5. The method of claim 1 , wherein the one or more metal wire strands include galvanized steel wire.
6. The method of claim 1 , wherein one or more of the one or more woven fibers and the one or more metal strands are coarsely woven.
7. The method of claim 1 , wherein a weave of one or more of the one or more woven fibers and the one or more metal strands is arranged to one or more of extend axially and skew with respect to a longitudinal axis of the reinforcing element.
8. The method of claim 1 , wherein the settable material is shear-resistant.
