Experimental study on Young’s modulus of concrete

Abstract

Young’s Modulus of concrete is studied on the basis of triaxial compressive experiments. The authors proposed two empirical equations to calculate its static Young’s modulus and dynamic Young’s modulus when dynamic Poisson ratio μ_d varies nearby 0.20. P-wave velocity and elastic modulus have the same varying tendency as letter N. μ, μ_d decrease with the increase of loading rate and μ_d has a great effect on the parameters E_d and E_D.
