ABSTRACT:
A method of bonding aggregates with resinous binder compositions to produce building materials of controlled strength, porosity and weight. Two types of building materials are made with this bonding method; one is a controlled strength, waterproof material, and the other is a controlled strength, porous material. The method employs either a phenolic resin binder composition in a semi-clear liquid form to maintain the natural coloration of the aggregate, or a furan resin binder composition which discolors the aggregate to a black or dark brown tone. In the controlled strength, waterproof product, the aggregate is gradated to provide a mixture of various particle sizes, including dust and fines, so that all the voids in the resulting product are filled. In the controlled strength porous product, the aggregate is gradated to provide a mixture of various particle sizes, excluding dust and fines, so voids in the product remain open, allowing moisture to pass through the product.
