is made by combining lime and pozzolana. Pozzolana is a siliceous or siliceous and aluminous material that, in itself, possesses little or no cementitious value but, in finely divided form and in the presence of water, reacts chemically with calcium hydroxide at ordinary temperatures to form compounds possessing cementitious properties.

The initial setting time of lime-pozzolana is the time it takes for the mixture to start to set. This is important because it determines how long the mixture can be worked before it becomes too hard to handle. The initial setting time of lime-pozzolana is typically 60 minutes, but it can vary depending on the type of lime and pozzolana used, the water-to-cement ratio, and the temperature.

Option A is incorrect because the initial setting time of lime-pozzolana is typically 60 minutes, not 30 minutes.

Option C is incorrect because the initial setting time of lime-pozzolana is typically 60 minutes, not 90 minutes.

Option D is incorrect because the initial setting time of lime-pozzolana is typically 60 minutes, not 120 minutes.
