RockRebar® is 80% based on one component, NATURAL volcanic basalt rock. Basalt rock covers 70% of the earth’s surface, and unlike the manmade recipe for white fiberglass. Basalt rock converted into a “glass-state” basalt fiber does not require toxic chemicals to create it! No contaminating waste is created from its production. Structural basalt glass fiber is cost effective, naturally renewable and Eco-Friendly. In its production, basalt rock is crushed and loaded into a furnace where it’s melted at extreme temperatures. The molten rock is further processed by being drawn through platinum bushings. As the fibers are drawn from the bushings, they are stretched taut, increasing fiber strength as their diameter is reduce up to 90%. A proprietary “size” solidifies each of the continuous, “glass-state” basalt fibers at 17 millionths of a meter as they exit the process at: Many Times The Tensile Strength Of Rusty Black Steel! We take thousands of these continuous strands of Basalt fiber, coat them with our proprietary epoxy resin adhesive and pass this matrix thru a series of compression dies forming a cylinder-type shape. Before the final curing, a Dacron® strand is wrapped tightly around the fibers to cause a “squeezing” shape change that will ensure concrete will fill in forming a mechanical grip to RockRebar®. To further enhance grip with concrete, a coating of resilient crush resistant quartz sand is applied to the bundle as it begins to solidify by heat curing. The final result. RockRebar®, a time tested, industry recognized and totally non-rusting alternative for traditional steel reinforcement.
