The shape of a load-deformation diagram of concrete is influenced by the properties of the material as well as by the testing conditions. Several of the numerical approximations presented for the stress-strain diagram can take some of these effects into consideration. The modulus of elasticity of a concrete is influenced by the same factors as the stress-strain diagrams. Formulae are offered for the estimation of the effects of concrete composition, including the porosity, on the modulus of elasticity. A discussion of the other elastic constants, poisson's ratio, etc., concludes the paper. A part of this paper presents new information, the other part is an organized summary of the state of the art.
