EFFECT OF SPEED OF TESTING ON FLEXURAL FATIGUE STRENGTH OF PLAIN CONCRETE

A FATIGUE INVESTIGATION OF CONCRETE TAKES CONSIDERABLE TIME, EVEN WHEN STATISTICS ARE APPLIED; CONSEQUENTLY THE TIME INVOLVED IN TESTING INDIVIDUAL SPECIMENS BECOMES OF PRIME IMPORTANCE. HENCE AN INVESTIGATION WAS STARTED TO DETERMINE THE EFFECT OF SPEED OF TESTING ON THE FINITE LIFE AND ENDURANCE LIMIT OF PLAIN CONCRETE IN FLEXURE. ABOUT 100 CONCRETE BEAMS WITH A CROSS SECTION 6 BY 6 IN. AND A LENGTH OF 64 IN. HAVE BEEN TESTED. THESE BEAMS WERE LOADED AT THE THIRD POINTS ON A SPAN OF 60 IN. TESTS WHERE CONDUCTED AT THREE SPEEDS, FROM 70 TO 440 C. P. M., AND FOR TWO CONCRETE STRENGTHS 3500 PSI. AND 4500 PSI. THE TESTS, SO FAR, INDICATE THAT THE SPEED OF TESTING HAS LITTLE EFFECT ON THE FATIGUE STRENGTH OF PLAIN CONCRETE. /AUTHOR/
