- B \(\mathrm{CaO}, \mathrm{Al}_2 \mathrm{O}_3\)
- C \(\mathrm{SiO}_2, \mathrm{MgO}\)
- D \(\mathrm{CaO}, \mathrm{MgO}\)
Answer & Solution
Correct Answer
(A) \(\mathrm{CaO}, \mathrm{SiO}_2\)
Step-by-step Solution
Detailed explanation
The portland cement consists of tricalcium silicate \((3 \mathrm{CaO} \cdot \mathrm{SiO}_2)\), dicalcium silicate \(\left(2 \mathrm{CaO} \cdot \mathrm{SiO}_2\right)\), tricalcium aluminate \(\left(3 \mathrm{CaO} \cdot \mathrm{Al}_2 \mathrm{O}_3\right)\) and tetra-calcium…
