A composite material structure can be constructed using an airforming process that includes filling the inflated support mold with a fluid structural material and allowing the fluid structural material to harden within the support mold. Additional steps can include inflating the support mold with a first fluid, forming fluid escape outlets in the support mold, and removing the support mold after allowing the fluid structural material to harden. The first fluid can be air, the support mold can be a fiberglass resin, and/or the fluid structural material can be a concrete composite material. Fluid can escape through the fluid escape outlets during the filling. The finished structure can include multiple structural components formed from a homogenous concrete composite material and having curved and non-planar geometries. The concrete composite material can include aluminum alloy fibers.

A composite material used to form a concrete structure that includes a concrete matrix formed of a mixture of aggregates and a paste and a mixture of twisted steel micro-reinforcements (TSMRs) dispersed within the concrete matrix. The TSMRs have a variable twist pitch; wherein the twist pitch of a portion of the TSMRs is in the range of 6 to 20 twists per 25.4 mm (1 inch) applied along its longitudinal axis. The TSMRs are made from a common base stock and have the number of twists predetermined, such that the concrete structure exhibits at least 10% greater performance in one or more of a stress, deflection, energy, or crack mouth opening (CMOD) properties as determined through one or more defined standard tests than a similar concrete structure formed with the same amount by weight of steel fibers having one or two bends.
