Method for producing fiber reinforced cement-based structural building materials

摘要

A composition for synthetic structural building materials, such as lumber, and the method used to fabricate such building materials. The synthetic building materials are molded from a composition that contains cement, sand, curing agents, water, synthetic fibers, a low density particulate and a curable polymer. These ingredients and a few others are mixed in unique ratios to produce a synthetic material that mimics the strength, flexibility, and weight of natural wood. The composition cures with time. Prior to curing, the composition is molded into the form of structural building materials, such as framing lumber and planks. Depending upon the intended purpose of the building materials, the composition can be molded around reinforcement elements that internally strengthen the composition when it is cured. The final piece of structural building material has a weight, strength and flexibility comparable to wood, yet is resistant to rot and insects.
