Question

Generally the two terms associated with cement: A. Portland
B. Sulphur
C. Ferric Nitrate
D. Aluminous
E. Sodium Chloride Choose the correct answer from the options below :

• A. A and D only
• B. B and C only
• C. C and E only
• D. A and B only

Hint:

Logic Tip: Portland and Aluminous are major industrial cement types.

Answer 1

The Correct Option is A

Concept:
Different types of cement are classified according to their composition and industrial usage. Two important types are:
• Portland Cement
• Aluminous Cement

Step 1:
Portland Cement is the most common type of cement used in:
• Construction
• Sculpture casting
• Architectural work Thus, option A is correct.

Step 2:
Aluminous Cement contains high alumina content and is used where:
• Heat resistance is required
• Rapid hardening is needed Thus, option D is correct.

Step 3:
Sulphur (B)
Not a standard cement category. Ferric Nitrate (C)
A chemical compound unrelated to cement classification. Sodium Chloride (E)
Common salt, not associated with cement types. Therefore, the correct pair is: \[ A \text{ and } D \] Hence, the correct answer is: \[ \boxed{\text{(1) A and D only}} \]
