Wang et al. [124] stated ideal Blaine fineness relies upon the kind of slag and fluctuates between 400 m 2 /kg and 550 m 2 /kg. The fineness of the binder and the percentage of fines of aggregate affect the fresh and hardened properties of concrete. As the fineness of the binder increases, corresponding workability, and strength increase.
