(57) The present disclosure relates generally to shaped aggregate particles and reinforcement for concrete. Specifically, but without limitation, the disclosure relates to plastic shaped aggregate particles. The plastic shaped aggregate particles may be made of/from recycled plastic. Such shaped aggregate particles may contain recycled and non-recycled glass fibers and particles, silica, or similar materials and/or combinations. The morphologies of the shaped aggregate particles include, but are not limited to, spherical particles, spiral structures, elongated ellipsoids, fibers, connected structures, spherical burst patterns, or similar structures such as tetrahedrons, rectangular prisms, and pyramids. The shaped aggregate particles may be made of recycled plastic waste and used with and without discontinuous glass fibers and/or similar materials such as chopped glass fibers and glass particles, for use in concrete applications as a filler and support.
