The effect of two artificial aggregate types and three kinds of mortar on the elastic modulus of concrete are reported. Bighteen batches of concrete with various volume fractions (10%, 20%, and 30%) were selected. Theoretical moduli were calculated based on micromechanics. Following recent studies of concrete as a twophase composite material, this study examines whether there is a relation between the elastic modulus of the constituents and concrete. From the examination of available experimental results, it is apparent that elastic modulus of concrete is affected by elastic modulus of constituents and volume fraction of aggregate. Test results were compared with the theoretical moduli and the theoretical predictions fairly agree with the experimental data.
