Preconditioned resin aggregate

Particles formed by the process of:

• obtaining a supply of plastic waste treated with a preconditioning agent that comprises at least one of calcium oxide and calcium hydroxide;
• mixing the supply of plastic waste treated with the preconditioning agent with one or more additives to form a plastic waste mixture, the one or more additives comprising pozzolans;
• hot extruding the plastic waste mixture to form an extruded product comprising waste plastic material;
• and
• processing the extruded product to form particles in which the waste plastic material is exposed at exterior surfaces thereof.

A method of making a concrete construction product, the method comprising:

• obtaining particles formed by hot extruding a plastic waste mixture comprising comingled mixed plastics, a preconditioning agent that comprises at least one of calcium oxide and calcium hydroxide, and pozzolans, cooling the extruded product, and processing the extruded product to a desired size of particles;
• mixing the particles with a cement mixture to form a concrete mixture;
• mixing the concrete mixture with water to generate a concrete slurry;
• and
• forming the concrete slurry into the concrete construction product.
