ABSTRACT:
A method for producing a lightweight, water resistant composition for use in manufacturing building materials and the composition produced by such method. The method comprising mixing a first mixture comprising an epoxy resin, a lightweight aggregate, a UV absorber and preferably sodium bicarbonate and a viscosifer in a rotary mixer, rotating at a speed of at least 40 rpm. A second mixture of an epoxy hardener, a lightweight aggregate, a UV absorber and preferably sodium bicarbonate and a viscosifer are mixed in a rotary mixer rotating at a speed of at least 1000 rpm while pressurized air is pumped in until the second mixture is homogenized. The first and second mixtures are then combined and mixed while pressurized air is pumped in until the combined mixtures are homogenized. The mixing process preferably is performed in a centrifugal mixer comprising a co-rotating disk agitator just prior to the time of manufacturing the building materials. A preferred lightweight, water resistant composition produced by the method of this invention comprises a curable composition resulting from the first mixture and second mixture prepared in accordance with the method describe herein and then combined and mixed until homogenized.
