Quick setting cement is produced by adding A. Less amount of gypsum in very fine powdered form B. More amount of gypsum in very fine powdered form C. Aluminium sulphate in very fine powdered form D. Pozzolana in very fine powdered form

The correct answer is: B. More amount of gypsum in very fine powdered form

Quick-setting cement is a type of cement that sets and hardens more quickly than ordinary Portland cement. It is made by adding more gypsum to Portland cement. The gypsum slows down the hydration of the cement, which allows it to set and harden more quickly.

Aluminium sulphate is a chemical compound that is used to accelerate the setting of cement. It is added to cement in small amounts to speed up the hydration process. Pozzolana is a type of volcanic ash that is used to improve the strength and durability of cement. It is added to cement in small amounts to improve its properties.

Here is a brief explanation of each option:

• Option A: Less amount of gypsum in very fine powdered form. This would result in a slower setting cement.
• Option B: More amount of gypsum in very fine powdered form. This would result in a quicker setting cement.
• Option C: Aluminium sulphate in very fine powdered form. This would result in a cement that sets more quickly.
• Option D: Pozzolana in very fine powdered form. This would result in a cement that is stronger and more durable.
