Claim 14:
15. A lightweight composite composition comprising:
a plurality of lightweight particles comprising a volume of at least about 10% of a total volume of the composite composition, the plurality of lightweight particles comprising an average bulk density within a range from about 0.001 grams per cubic centimeter to about 1.5 grams per cubic centimeter and an average particle size within a range from about 0.01 microns to about 90 millimeters, further comprising a binder material in contact with the plurality of lightweight particles, the binder material comprising a volume within a range from about 5% to about 40% of the total volume of the lightweight composite composition, the binder material comprising one or more of a cement, pozzolan, gypsum, Portland cement, calcium aluminate, or calcium sulfoaluminate, wherein the plurality of lightweight particles comprise a non-volcanic ash material comprising one or more of polymer pellets, polymer foam beads, crushed glass, foamed glass spheres, hollow glass microspheres, polymer microspheres, polymer capsules, polymer micro-balloons, or carbon-based pellets; and
an aggregate up to about 60% of the total volume of the lightweight composite composition, the aggregate comprising one or more of recycled concrete, reclaimed material, sand, gravel, clay or crushed stone, wherein the plurality of lightweight particles and the aggregate are homogenously dispersed and mixed throughout the binder material, wherein the lightweight composite composition comprises a compressive strength of at least 10 pounds/in2, and a bulk density within a range from about 15 pounds per cubic foot to about 135 pounds per cubic foot.
