Q: Pick up the correct proportions of chemical ingredients of cement.
  • A. lime : Silica : Alumina : Iron oxide = 63 : 22 : 6 : 3
  • B. Silica : Lime : Alumina : Iron oxide = 63 : 22 : 6 : 3 (
  • C. Alumina : Silica : Lime : Iron oxide = 63 : 22 : 6 : 3
  • D. Iron oxide : Alumina : Silica : Lime = 63 : 22 : 6 : 3
Correct Answer: Option A - The proportion of chemical Ingredients of cement Average Lime (60–65%) 63 Silica (17–25%) 20 Alumina (3 – 8%) 6 Iron Oxide (0.5 – 6%) 3 Magnisium (0.1 – 4%) 2 Sulphur Trioxide (1 to 3%) 1.5 Soda and potash (0.5 ti 1.3% ) 1 Gypsum 2 to 3%
