Patent ID: 7875231

Claim:
A method of fabricating artificial lumber that has a compressive strength of at least 3000 pounds per square inch and a density under eighty pounds per cubic foot so as to better mimic natural wood lumber, said method comprising the steps of: providing a synthetic composition containing a mixture of cement, sand, curing agents, water, synthetic fibers, a low density particulate and a curable polymer, wherein said cement is provided in amounts between 550 and 650 pounds per cubic yard, said synthetic fibers are added in amounts between 5 and 10 pounds per cubic yard, said low density particulate is added in amounts between 75 and 125 pounds per cubic yard, and said curable polymer is added in amounts between 3 and five pounds per cubic yard; providing reinforcement elements; and molding said synthetic composition around said reinforcement elements, wherein said synthetic composition cures and forms a segment of artificial lumber internally reinforced by said reinforcement elements.
