The correct answer is: C. Hydraulic lime
Hydraulic lime is a type of lime that can set and harden even when
it is in contact with water. This makes it ideal for use in mortar, which is a mixture of lime, sand, and water that is used to bind bricks and stones together.Quick lime is a type of lime that is produced by heating limestone to a high temperature. It is a very strong base and can be used to make a variety of products, including mortar, plaster, and whitewash. However, it is not suitable for use in hydraulic lime mortar, as it will not set properly when it is in contact with water.
Fat lime is a type of lime that is produced by burning limestone at a lower temperature than quick lime. It is less strong than quick lime, but it is more workable and can be used to make a variety of products, including mortar, plaster, and whitewash. It can also be used to make hydraulic lime mortar, but it is not as strong as hydraulic lime made from pure limestone.
Plain lime is a type of lime that is produced by burning limestone at a very low temperature. It is the weakest type of lime and is not suitable for use in mortar or plaster. It can be used to make whitewash, but it is not as effective as fat lime or quick lime for this purpose.
In conclusion, the correct answer to the question “Lime mortar is generally made with” is “C. Hydraulic lime.”
