DIRECT TENSILE STRENGTH TEST OF CONCRETE

THE SHORTCOMINGS ARE DESCRIBED OF THE INDIRECT METHODS PRESENTLY USED TO DETERMINE THE TENSILE STRENGTH OF CONCRETE. A NEW METHOD FOR TESTING THE DIRECT TENSILE STRENGTH OF CONCRETE, DEVELOPED AT THE BUILDING RESEARCH INSTITUTE OF PRAGUE TECHNICAL UNIVERSITY, IS PRESENTED. THE APPLIANCE CONSISTS OF A TIE ROD WITH A PIVOT JOINT MOUNTED IN A CYLINDRICAL HEAD WITH A SLEEVE. THE HEAD IS SCREWED INTO A THICK STEEL END PLATE, WHICH IS GLUED TO THE END OF TENSILE TEST SPECIMEN. A CZECHOSLOVAK BONDING ADHESIVE, CHS EPOXY 1200 RESIN, IS EMPLOYED FOR THE GLUING. IT IS CURED AT AMBIENT ROOM TEMPERATURE FOR 48 HOUR WITH AN AID OF A SETTING AGENT. THE DIRECT TENSILE STRENGTH, SPLITTING TENSILE STRENGTH AND MODULUS OF RUPTURE TEST RESULTS IN RELATION TO THE DYNAMIC MODULUS OF ELASTICITY OF BEAM TEST SPECIMENS AT 14 AND 28 DAYS ARE COMPILED IN TABLES AND SHOWN IN GRAPHS.
