CONCRETE-POLYMER MATERIALS FOR HIGHWAY APPLICATIONS-PROCESS REPORT NO. 1

AN INCREASE IN COMPRESSIVE STRENGTH OF ABOUT THREE-FOLD CAN BE OBTAINED WITH BOTH HIGH AND LOW QUALITY CONCRETES BY IMPREGNATING THE CONCRETE WITH METHYL METHACRYLATE MONOMER AND THEN POLYMERIZATION BY EITHER RADIATION OR THERMAL CATALYTIC MEANS. THE STRENTH OF LIGHTWEIGHT INSULATING CONCRETE IN SOME CASES HAS BEEN INCREASED FROM A STRENGTH OF 100 PSI TO ABOUT 4,000 PSI. TESTS ALSO INDICATE THAT CREEP IS LESS THAN ONE-TENTH THAT OF THE CONTROL CONCRETE. THE ABRASIVE RESISTANCE OF THE CONCRETE HAS BEEN IMPROVED BY A FACTOR OF ABOUT TWO. IMPREGNATION OF STRUCTURAL LIGHTWEIGHT CONCRETE HAS GIVEN COMPRESSIVE AND TENSILE STRENGTHS OF 18,000 AND 2,000 PSI, RESPECTIVELY. EFFORTS ARE NOW BEING MADE TO PREPARE SPECIMENS OF GREATER UNIFORMITY. PRELIMINARY DESIGN STUDIES USING COMPUTER-CODED FINITE ELEMENT ANALYSIS WERE MADE TO DETERMINE THE FEASIBILITY OF USING CONCRETE-POLYMER MATERIALS FOR PRECAST BRIDGE DECKS AND BREAKAWAY LAMP POSTS. BASED ON THE LIMITED DATA ON PROPERTIES, BOTH APPLICATIONS APPEAR ATTRACTIVE. ADDITIONAL DATA UNDER STATIC AND DYNAMIC TEST CONDITIONS ARE REQUIRED BEFORE A DETAILED STRUCTURAL DESIGN AND COST ESTIMATE CAN BE MADE. /AUTHOR/
