DYNAMIC TENSILE STRENGTH OF CONCRETE MATERIAL

THE DYNAMIC TENSILE STRENGTH OF PLAIN CONCRETE, FIBER REINFORCED CONCRETE, AND A POLYESTER CONCRETE IS EVALUATED IN TERMS OF THE CRITICAL FRACTURE STRAIN ENERGY. BASED ON THE FRACTURE STRAIN ENERGY REMAINING CONSTANT, IT WAS SHOWN THAT THE FRACTURE STRAIN SHOULD VARY AS THE ONE-THIRD POWER OF STRAINING RATE OR THE INVERSE ONE-HALF POWER OF RISE TIME. THIS WSA EXAMINED ON PRISMATIC SPECIMENS OF THREE TYPES OF CONCRETE AND FOUND TO AGREE WITH EXPERIMENTAL RESULTS. THE TESTS WERE ACCOMPLISHED USING AN IMPACT LOADER AND A STRAIN GAGE SYSTEM. THE PAPER ALSO POINTS OUT THE RELATIONSHIP OF THIS TYPE OF TEST TO THE GENERAL PROBLEM OF SPALLATION OF CONCRETE BY DYNAMIC TENSILE PULSES. /ACIJP/
