EPOXY-RESIN ADHESIVES FOR BONDING CONCRETE TO CONCRETE

THE HISTORY OF EPOXY-RESIN ADHESIVES FOR BONDING CONCRETE AND OTHER MATERIALS TO CONCRETE IS REVIEWED. DURING THE SHORT HISTORY OF COMMERCIAL USE, EPOXY-RESIN ADHESIVES HAVE EVOLVED INTO TWO BASIC TYPES: THOSE CAPABLE OF BONDING PLASTIC OR HARDENED CONCRETE TO CONCRETE, AND FASTER-CURING SYSTEMS DEVELOPED FOR BONDING HARDENED CONCRETE OR OTHER RIGID STRUCTURAL MATERIALS TO CONCRETE. EXPERIENCE HAS SHOWN THAT PROPER SURFACE PREPARATION DETERMINES THE SUCCESS OF CONCRETE BONDING. MECHANICAL ABRADING HAS PROVEN THE MOST RELIABLE METHOD OF SURFACE PREPARATION. ACID WASHING MAY LEAD TO VARIABLE RESULTS. ALTHOUGH LITTLE DIFFICULTY HAS BEEN EXPERIENCED IN THE FIELD, EPOXY-RESIN ADHESIVES MAY CAUSE SENSITIZATION OF INDIVIDUALS COMING IN CONTACT WITH THEM. PRECAUTIONS AND TOXIOCOLOGICAL DETAILS ARE COVERED. AT PRESENT, THERE ARE NO STANDARD TEST METHODS FOR EVALUATING EPOXY-RESIN ADHESIVES FOR USE WITH CONCRETE ALTHOUGH THE DIAGONAL-TENSION TEST HAS PROVEN REPRODUCIBLE. THE WRITING OF STANDARD SPECIFICATIONS FOR THESE ADHESIVES AWAIT THE ACCEPTANCE OF STANDARD TEST PROCEDURES. /ACIJP/
