Abstract
A lightweight foamed polymer concrete admixture for use in fabricating building components, the polymer concrete comprising a mixture of a polyol, an isocyanate, an aggregate, and water, wherein once mixed, the mixture releases carbon dioxide gas creating a foamed mixture that may be shaped to form a building component such as, but not limited to, lap siding, shake siding, trim boards, stone and stucco sheeting.
Claims9
A polymer concrete composition useful for fabricating lightweight building products, the polymer concrete composition comprising;
- (a) aggregate in an amount in the range from about 50 to 90% by weight of the polymer concrete composition;
- (b) polyol in an amount in the range from about 10 to 20% by weight of the polymer concrete composition;
- (c) isocyanate in an amount in the range from about 5 to 15% by weight of the polymer concrete composition;
- and
- (d) water in an amount of at least 0.1% by weight of the polymer concrete composition, wherein the sum of the components (a) through (d) add up to 100 weight % and after the product is cured in a continuous belt mold the polymer concrete exhibits a density of from about 0.7 to 1.5 g/cm3 and a flexural strength of from about 0.6 to 1.0 Mpa.
