Keywords： self-compacting concrete

To meet the requirements of construction of concretes filled in the steel tube arches,a C60 grade micro-expansive self-compacting concrete (SCC) was prepared from manufactured sand (MS). The utilization of MS with a high content of quarry limestone fines was dealed for SCC applications. The workability, compressive and splitting strength, modulus of elasticity, restrained expansion and chloride ion permeability as well as freeze-thaw resistance of three MS-SCC mixes with fines content of 3%, 7% and 10% were tested and compared with those of the natural sand (NS)-SCC mix.The experimental results indicate that the performances of the C60 MS-SCC with fines content of 7%are excellent and compared favorably with those of C60 NS-SCC.
