EFFECT OF CERTAIN VARIABLES ON PULSE VELOCITIES THROUGH CONCRETE

SONISCOPE TESTING OF CONCRETE SPECIMENS SHOWED THAT THERE ARE MANY VARIABLES THAT INFLUENCE THE VELOCITY. TEST RESULTS WERE (1) PULSE VELOCITIES THROUGH CONCRETE CONTINUE TO INCREASE DURING MOIST CURING OF THE CONCRETE TO AGES OF 56 DAYS, (2) PULSE VELOCITIES THROUGH NEAT CEMENT PASTE ARE APPRECIABLY LOWER THAN THOSE THROUGH CONCRETE CONTAINING THE PASTE, (3) FOR THE SAME WATER-CEMENT RATIO AND MAXIMUM SIZE OF AGGREGATE, THE PULSE VELOCITY WILL VARY MARKEDLY WITH AGGREGATE TYPE, (4) FOR THE SAME WATER-CEMENT RATIO AND TYPE OF AGGREGATE, THE PULSE VELOCITY INCREASES AS THE MAXIMUM SIZE OF AGGREGATE INCREASES AND AS THE PERCENTAGE OF PASTE DECREASES, (5) FOR THE SAME MAXIMUM SIZE AND TYPE OF AGGREGATE, THE PULSE VELOCITY DECREASES AS THE WATER-CEMENT RATIO INCREASES, AND (6) A RELATIONSHIP BETWEEN COMPRESSIVE STRENGTH AND PULSE VELOCITY CAN BE DETERMINED BUT IT IS DIFFERENT FOR EACH AGGREGATE AND AGGREGATE GRADUATION.
