Through compressive tests of 126 (150mm150mm300mm) and 63 specimens ( 150mm150mm150mm) of plain and fiber reinforced high-strength concrete, the effects of fiber types and volume fractions on elastic modulus of highstrength concrete, and the relation between elastic modulus and compressive strength were studied. Based on the discussion on the elastic modulus of high-strength concrete, the calculating formula of elastic modulus of fiber reinforced high-strength concrete was put forward, good agreement between the calculated values and the test results was found.
