JEE MAIN - Chemistry (2023 - 8th April Evening Shift - No. 7)
For a good quality cement, the ratio of lime to the total of the oxides of $$\mathrm{Si}, \mathrm{Al}$$ and $\mathrm{Fe}$ should be as close as to :
3
2
1
4
Explanation
For good quality cement, the ratio of lime (CaO) to the sum of the oxides of silicon (SiO₂), aluminum (Al₂O₃), and iron (Fe₂O₃) should be approximately 2:1.
This proportion ensures that the cement has good strength and setting properties, as well as resistance to chemical attack.
