The elastic moduli of cement-based composite materials with different types of aggregates were investigated in this study. Twelve mixes with various volume fractions (10%, 20%, and 30% ) were selected. Cylindrical specimens with a dimension of ∮ 10 x 20 cm were cast and tested. Electric strain gages were used and elastic moduli were obtained from the stressstrain curves. Theoretical moduli were calculated based on H-S bounds and micromechanics. Test results show that the types and volume fractions of aggregates significantly affect the elastic moduli of concrete composite materials and the theoretical predictions fairly agree with the experimental data.
