(57) A concrete formulation containing a binder, which may or may not be cementitious, and at least one aggregate. The aggregate includes at least two plastic materials of the following types, which may be sourced from recycled or reprocessed waste: polyethylene (PE), polyethylene terephthalate (PET), polypropylene (PP), polystyrene (PS), polyvinyl chloride (PVC), nylon, polylactic acid (PLA), rubber, or their copolymers. The plastic may be processed to form granulated particles such as pellets, chips (fig. 2), flakes (fig. 3), or a mixture of these, and may be used to replace up to 100% of any conventional, coarse aggregatewithin the concrete. The formulation may also be used to produce ready mix concrete, concrete masonry units (CMUs), interlocking concrete blocks, and other similar products. The CMU may contain between 1 and 19% by weight of any aggregate content as plastic. The use of plastic as an aggregate is intended to lower the environmental impact of the concrete and subsequent products.
