ABSTRACT:
Composite products formed from at least one piece of wood and a resinated hydraulic cement and the method for their preparation are described. The predominantly mechanical bond between wood and hydraulic cement achieved by the prior art is significantly improved because of the presence of a thermoset resin in the cement such that adhesion occurs at the wood-cement interfaces by specific action of the resin, and a bond of greater integrity results. The cement and the resin function synergistically to consummate a bond with the wood wherein the resin performs the adhesion action and the cement performs a reactive filler or bulking action. The resulting composite products are stronger, more durable and can be made at lower densities than prior art products.
