The experiment was carried out to investigate the influence of coarse aggregate, admixture, and accelerator on the properties of concrete. As the maximum size of coarse aggregate decreased from 13 mm to 8 mm, fluidity of fresh concrete declined but compressive strength and dynamic modulus of elasticity of hardened concrete increased remarkably. The mechanical properties of concrete substituted silica fume to the plain concrete improved, the compressive strength of that substituted blast furnace slag increased slightly. The hydration reaction and compressive strength of specimen with sodium aluminate type accelerator were high at initial, but specimen with alkali free type accelerator improved largely in 28 days.
