Abstract:
A method of making a structural lightweight and thermal insulating concrete is described. The concrete has a coarse aggregate partly replaced by recycled plastic pieces. This enables the concrete to maintain a high compressive strength, low thermal conductivity, and low weight, while providing a use for waste plastic. The waste plastic pieces may comprise polyethylene in the form of flakes, fibers, or granules. Due to its low unit weight, adequate compressive strength and high thermal resistance the developed concrete can be used as a structural lightweight and thermal insulating concrete. The use of this concrete leads to economic and environmental benefits.

Claim (Index 1):
A method of making a structural lightweight concrete, the method comprising:\n mixing:\n 12-25 wt % Portland cement; \n 37-57 wt % fine aggregate; \n 5-40 wt % coarse aggregate; and \n 5-12 wt % water to form a wet concrete slurry, wherein each weight percentage is relative to a total weight of the wet concrete slurry; and \n curing the wet concrete slurry to produce the structural lightweight concrete, wherein the coarse aggregate comprises 10-100 wt % waste plastic pieces, relative to a total weight of the coarse aggregate, the waste plastic pieces having an average longest dimension of 1-12 mm.
