Consider the following cements: Cement 1: CEM I 42.5 R with Blaine fineness of 3500 cm2/g Cement 2: CEM I 42.5 R with Blaine fineness of 3800 cm2/g Cement 3: CEM II/B-W 42.5 R with Blaine fineness of 3500 cm2/g Cement 4: CEM II/B-W 42.5 R with Blaine fineness of 3800 cm2/g (Assume that same clinker and mineral admixture is used in these cements) a) Which cement is supposed to be cheaper? Why? b) Which cement is supposed to be more suitable for hot weather? Why? c) Which cement is supposed to have the highest early strength? Why? d) Which cement is supposed to give less damage to the environment? Why?
