摘要： A METHOD AND RESULTING STRUCTURAL BUILDING UNIT WHEREIN A CEMENT BLOCK, FOR EXAMPLE, HAS A PORTION REMOVED, IF NECESSARY, TO GIVE IT A PREDETERMINED VERTICAL HEIGHT. THE PRESIZED BLOCK IS PLACED UPON A CONTINOUSLY MOVING COMVEYER AND ONE SIDE OF THE BLODK IS PREHEATED AND THEN COATED WITH A LIQUID METAL COMPRISING A POLYESTER RESIN, A STYRENE MONOMER, A SOLVENT, AND A CATALYST. THE STORED HEAT IN THE BLOCK QUICKLY EVAPORATES THE SOLVENT AND POLYMERIZES THE RESIN AND MONOMER SO THAT A STRONGLY ADHERING BONDING COAT IS FORMED ON THE BLOCK. A LAYER OF MATRIX MATERIAL OF RELATIVELY THICK CONSISTENCY, COMPRISING A POLYESTER RESIN, A STYRENE MONOMER, FINELY DIVIDED SILICA, COLLOIDAL SILICA, AND CATALYST IS APPLIED TO THE COATED BLOCK. THE LAYER OF MATRIX MAY BE 1/8" THICK OR THICKER, DEPENDING UPON THE TYPE OF BUILDING UNIT THAT IS BEING MADE. SLABS OF BRICK OR OTHER MATERIAL ARE PARTIALLY EMBEDDED IN THE MATRIX, IN SPACED RELATION, TO FORM A FACING FOR THE BLOCK WITH SIMULATED MORTAR JOINTS. SAND IS SPRINKLED ON THE FACING MTERIAL AND THE EXPOSED MATRIX. THE MATRIX IS THEN CURED OR POLYMERIZED BY PASSING THE BLOCK THROUGH A CURING OVEN. THE MATRIX PERMANENTLY BONDS THE FACING MATERIAL TO THE BLOCK, AND RENDERS THE COVERED SIDE OF THE BLOCK IMPERVIOUS TO MOISTURE. THE SAND ADHERES TO THE MATRIX, BUT IS READILY REMOVABLE FROM THE FACING SLABS.
