Abstract:
LONGITUDINAL WAVE VELOCITIES THROUGH A SELECTED GROUP OF CONCRETE TEST BEAMS AND THROUGH A SLAB IN SITU WERE DETERMINED WITH THE INTERVAL TIMER, AND FLEXURAL STRENGTH VALUES WERE PREDICTED BY APPLICATION OF APPROPRIATE FORMULAS. ACTUAL FLEXURAL STRENGTHS OF THE TEST BEAMS AND OF BEAMS CUT FROM THE SLAB WERE DETERMINED BY CONVENTIONAL TECHNIQUE, AND THESE RESULTS ARE COMPARED STATISTICALLY AND PRACTICALLY WITH THE PREDICTED VALUES. THE VALIDTY OF A GENERAL CORRELATION BETWEEN DYNAMIC MODULUS OF ELASTICITY AND FLEXURAL STRENGTH OF CONCRETE IS BRIEFLY REVIEWED. ADDITIONAL RELATED INFORMATION PERTINENT TO THE USE OF THE INTERVAL TIMER IS DISCUSSED. /AUTHOR/
