ABSTRACT:
A low cost, lightweight, high strength, long lasting, crack resistant, monolithically formed composite structural material and the method of making the same in which the composite consists of a core constructed from lightweight, granulated scrap or waste plastic bonded together with a cementitious slurry binder. The core is covered on one or more of its sides with a high strength outer layer constructed of layers of non-woven fabric material impregnated with the same cementitous slurry binder with the fibers in the layers of non-woven fabric material forming a three-dimensional reinforcement matrix for the cementitous slurry. The composite of the core and covering is co-formed and cured monolithically with the cementitious slurry being continuous throughout the fibers of the layers of non-woven fabric and the core with the lightweight scrap or waste plastic serving as an aggregate for the core. The composite structural material can be molded or formed in various shapes and configurations for various purposes.
