Vedclass · Answer

(A) For a good quality cement,the chemical composition is strictly controlled to ensure proper setting and strength.The ratio of silica $(SiO_2)$ to alumina $(Al_2O_3)$ is maintained in the range of $2.5-4.0$.Additionally,the ratio of lime $(CaO)$ to the sum of silica,alumina,and iron oxide $(SiO_2 + Al_2O_3 + Fe_2O_3)$ is kept between $2.0$ and $3.0$.

For a good quality cement,the ratio of silica to alumina should be in the range of:
