Abstract EN
There are numbers of equations to evaluate the modulus of elasticity by current codes and researchers.
This paper aims in developing an empirical equation to evaluate the modulus of elasticity for High Strength Concrete (HSC) considering the Iraqi aggregates used in producing the HSC.
The analysis consider 78 tests from the available literature using Iraqi aggregates with a wide range of compressive strength of concrete from 41 to 83.3 MPa.
The comparisons between the proposed equation here and the current codes ACI 318-14, EC2-02 and the equation by Noguchi show that for the ACI 318-14, there is an overestimation of 80% of the tests that are below it, while EC2 values are too conservative as they are below 78% of test results.
The equation by Noguchi et al.
showed better evaluations as it is very close to the proposed equation.
More tests are required to finalize the developed equation, which cover all the parameters influecing modulus of elasticty in the produced HSC
