Abstract
An aggregate includes a polymeric foam present in a range of about 80 vol % to about 85 vol % of the aggregate. A cementitious matrix is present in a range of about 10 vol % to about 13 vol % of the aggregate. One or more resins are present in an amount of less than about 2 vol % of the aggregate, and one or more reinforcing fibers are present in an amount of less than about 1 vol % of the aggregate.

An aggregate comprising:
- a polymeric foam present in a range of 80 vol % to 85 vol % of the aggregate, the polymeric foam comprising at least one of waste polymeric foams, thermoset foams, elastomeric foams, and combinations thereof;
- a cementitious matrix present in a range of about 10 vol % to 13 vol % of the aggregate;
- one or more reinforcing fibers present in an amount of less than 1 vol % of the aggregate;
- and
- one or more water-based resins present in an amount of less than 2 vol % of the aggregate, the one or more water-based resins comprising at least one of polyurethane resins, epoxy resins, styrene maleic resins, and combinations thereof,
- wherein the aggregate has a density in a range of 350 kg/m3 to 550 kg/m3.
