Abstract
A building material composition comprises a mixture of a styrenated unsaturated polyester with hydrated alumina at a ratio of one part by volume polyester to 0.5 to one part hydrated alumina. The mixture is cured by adding a methyl ethyl Ethyl ketone peroxide as a catalyst. Other ingredients, such as dry clean sand, perlite, and/or calcium carbonate may be added to the mixture prior to the addition of the catalyst. The resulting composition exhibits superior strength characteristics as a building material.
