Please tell me answer of this question.

Answer should B. Because pozzolana have property of increasing strength, by reaction with cement.

Increase setting time of cement so option E is correct.

Addition of pozzolana to cement make the following statement:
1. Increasing strength.
2. Delay setting of cement.
3. Decreasing heat of hydration (the reacting between cement and water).
4. Increasing durability and serviceability.
5. Decreasing porosity of concrete.
So; the choose number B is correct.
1. Increasing strength.
2. Delay setting of cement.
3. Decreasing heat of hydration (the reacting between cement and water).
4. Increasing durability and serviceability.
5. Decreasing porosity of concrete.
So; the choose number B is correct.

Yes, b is the correct answer.

Most of the bits are wrong.
Ca(OH)2 + pozzolana = C-S-H (Denser Gel).
There by increasing the Strength.
Ca(OH)2 + pozzolana = C-S-H (Denser Gel).
There by increasing the Strength.

B is the correct option. I agree.

The strength of the concrete is increased, its density is increased.
Efflorescence is decreased.
The propensity for alkali-silica reaction (reaction with glass) is decreased or even virtually eliminated.

Pozzolana. Responsible for quick setting so option E.
