Solution:
For a good quality cement, the ratio of silica to alumina should be between 2.5 and 4 and the ratio of lime (CaO) to the total of the oxides of silicon aluminium and iron should be as close as possible to 2.
For a good quality cement what should be the ratio of following
I. Silica to alumina
II. CaO to the total of oxides of and
