Benefits of technology
The invention is about using continuous glass fibers, such as basalt, to reinforce concrete structures. This helps to make roads, sidewalks, and other infrastructures stronger and more durable. The basalt reinforcing member provides additional support to reduce bending moments and help prevent shear. Other types of continuous glass fibers can also be used, such as borosilicate glass, volcanic basalt glass, and carbon fiber. Overall, this technology improves the performance of cement-based materials and plastics.
Problems solved by technology
It has been identified that the ultimate load capacity of a steel or fiber reinforced polymer concrete beam, column, panel or street is limited by the rupture strength of the stirrups to delay the onset of shear within the concrete.

Embodiment Construction
[0035]Disclosed herein is an improved reinforcement matrix member for concrete structures or reinforced pavements. Specifically, the matrix member works with concrete material by forming a structural support use in reinforcing concrete structures, pavements, roads, sidewalks and other infrastructure conventionally reinforced with rebar. Through the use of embodiments of the present invention, the concrete structure can be made stronger by adopting the high tensile, low stretch characteristics of continuous basalt fiber configured into a geometry that acts to tighten to the concrete it reinforces as load increases. The material and method of construction extends the onset of bond slit to beyond the limits of the concrete matrix it reinforces resulting in a somewhat self-healing structure where the lack of memory after a temporary overload will allow the structure to return to its original shape. In particular, the continuous glass fibers are formed into rectilinear shape with corners...

Matrix basalt reinforcing member constructed and arrange to provide lateral support for the longitudinal bar steel or FRP tendons that provide tensile strength to cementitious material or plastics to reduce bending moment by reducing the onset of shear. The reinforcement members are formed from continuous glass fibers treated with a thermoplastic thermoset polymer and formed into structures to provide structural resistance to bending-moment forces, compression forces, and torsional forces acting on the structure.
Description
PRIORITY CLAIM[0001]In accordance with 37 C.F.R. 1.76, a claim of priority is included in an Application Data Sheet filed concurrently herewith. Accordingly, the present invention claims priority as a continuation-in-part of U.S. patent application Ser. No. 15 / 068,198, entitled “BASALT REINFORCEMENT FOR CONCRETE CONTAINMENT CAGES”, filed Mar. 11, 2016, which claims priority to U.S. Provisional Patent Application No. 62 / 131,889, entitled “BASALT REINFORCEMENT FOR CONCRETE CONTAINMENT CAGES”, filed Mar. 12, 2015. The contents of the above referenced applications are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates broadly to concrete reinforcement, and more particularly, to reinforcement members made from continuous fiber glass in a configuration to improve tensioning in concrete and reinforced masonry structures.BACKGROUND OF THE INVENTION[0003]Concrete is very strong in compression, but relatively weak in tension. To compensate for this imbalance i...
