Polymer masonry unit and method therefor
A polymer masonry unit is disclosed that can include a polymer added to a quarry byproduct to manufacture a quality brick unit. The present disclosure solves the technological problem of providing a structurally sound brick or concrete alternative without the need for kiln firing, using traditionally unusable waste material. By combining quarry byproduct and a polymer, a polymer masonry unit can be fabricated having compressive strength and architectural utility. In one exemplary embodiment, fiber elements can be added to the byproduct and polymer mixture to increase structural stability. The present disclosure improves the performance of the system itself by providing a basic block or brick unit using an environmentally responsible manufacturing process that reduces cost and waste. The manufacturing process includes a polymer/base material that can be poured into molds that cures over a predetermined period, without the need for kiln firing.
