COMPARATIVE MEASUREMENTS BY STATIC AND DYNAMIC METHODS TO DETERMINE YOUNG'S MODULUS AND POISSON'S RATIO OF PLAIN CONCRETE.

Abstract

Attempts were made to seek a relationship between values of Young's modulus and Poisson's ratio as found by the NCEL sonic device and the NCEL compressometer. The dynamic method (resonant frequency measuring device) of determining Young's modulus of elasticity for concrete was found to be a more reproducible method of testing than the static method (compressometer). Dynamic measurements were made for the transverse, torsional, and longitudinal resonant frequencies of each concrete cylinder. Compressometer readings were then taken at 100 and 1000 psi; the cylinder was then compressively loaded to failure. No conclusive proof was found to demonstrate a definite relationship between the dynamic and static methods of determining the value of Young's modulus. (Author)
