THE IMPACT STRENGTH OF CONCRETE USING GREEN'S BALLISTIC PENDULUM

AN EXTENSIVE INVESTIGATION HAS BEEN CARRIED OUT USING THE IMPACT TEST DEVLOPED BY GREEN. IT IS SHOWN THAT THIS TEST CAN GIVE VERY CONSISTENT RESULTS IF THE AVERAGE ENERGY PER BLOW TO 'NO-REBOUND' IS USED AS THE CRITERION FOR THE IMPACT STRENGTH OF CONCRETE. THE EFFECTS OF VARYING THE MIX PROPORTIONS, BY CHANGING THE C/W RATIO, CEMENT CONTENT AND COARSE/FINE AGGREGATE RATIO, ON IMPACT STRENGTH WERE INVESTIGATED. THE EFFECTS OF FOUR TYPES OF COARSE AGGREGATE, DIFFERENT MAXIMUM SIZES OF AGGREGATE, DIFFERENT AGES AND TWO TYPES OF CEMENT WERE ALSO CONSIDERED. THE RESULTS IN GENERAL, INDICATED A REMARKABLE CORRELATION BETWEEN IMPACT STRENGTH AND UNIAXIAL (STATIC) COMPRESSIVE STRENGTH. /RRL/A/
