Abstract：Through the tests of fluidity,ratio of water demand,activity index of mortar,concrete workability and compressive strength, a unitary regression equation was established to study the influence of microbeads on C60 high-strength commercial con-crete. The results indicate that beads can improve the early strength of concrete. The workability of concrete is improved obviously with the increase of the amount of beads replacing the fly ash,and the effect of viscosity reduction is good. The 7 d and 28 d compressive strength of concrete is 68.7 MPa and 84.9 MPa when the substitution of beads is 100%. The unitary regression equa-tion and analysis indicate that beads have obvious influence on the compressive strength of concrete at different age.
