THE ESTIMATION OF THE ELASTIC MODULUS OF CONCRETE FOR THE DESIGN OF STRUCTURES

This paper shows that the elastic modulus of concrete depends on the aggregate used, the compressive strength of the concrete, the aggregate/cement ratio and the age at test. It is suggested that the estimation of the elastic modulus E should be made at one of three levels, the choice depending on the importance of the estimate. At level 1, a constant elastic modulus of 30 kn/mm2 is proposed for concrete made with natural aggregates. At level 2, the elastic modulus is estimated for the required compressive strength from either a linear or a power relationship. The modulus of elasticity of concrete at ages other than 28 days can be estimated from the 28-day value from an equation. At level 3 where the elastic modulus is of great importance, tests should be carried out on concrete made with the aggregate to be used in the structure. /TRRL/
