CONCRETE-POLYMER COMPOSITES

INVESTIGATIONS OF CONCRETE-POLYMER COMPOSITES HAVE INDICATED THAT REMARKABLE IMPROVEMENTS IN THE STRUCTURAL AND DURABILITY PROPERTIES OF CONCRETE CAN BE OBTAINED BY MONOMER IMPREGNATION AND IN-SITU POLYMERIZATION BY EITHER RADIATION OR CHEMICAL- INITIATORS. IMPROVEMENTS IN COMPRESSIVE, TENSILE, AND FLEXURAL STRENGTHS OF ALMOST A FACTOR OF FOUR TIMES THAT OF CONCRETE HAVE BEEN OBTAINED FOR SAMPLES CONTAINING 6 WEIGHT PERCENT POLYMER. SIGNIFICANT IMPROVEMENTS IN DURABILITY WERE ALSO NOTED. METHYL METHACRYLATE-IMPREGNATED SPECIMENS HAVE NOT FAILED AFTER EXPOSURES OF LESS THAN 1 YR TO SULFATE BRINES AND 15 % HYDROCHLORIC ACID. EXPOSURE TO 5,120 CYCLES OF FREEZING AND THAWING HAS RESULTED IN ESSENTIALLY NO ATTACK. APPLICATIONS BEING EVALUATED INCLUDE CORROSION RESISTANT CONCRETE FOR DESALINATION PLANTS, BEAMS AND WALL PANELS IN HOUSING, UNDERWATER STRUCTURES, BRIDGE DECKS, ROADS, AND PROTECTIVE BARRICADES. /AUTHOR/
