The correct answer is: D. All of the above
Quicklime is obtained by burning pure limestone at a high temperature. This process is called calcination. The resulting product is a white powder that is highly reactive. Quicklime is used in a variety of applications, including the manufacture of cement, mortar, and plaster.
Hydraulic lime is a type of lime that can set and harden under water. It is produced by burning limestone that contains a small amount of clay. The clay acts as a flux, which helps to reduce the melting point of the limestone and allows it to form a hydraulic cement. Hydraulic lime is used in a variety of applications, including the construction of dams, bridges, and other infrastructure.
Poor lime is a type of lime that is produced by burning limestone that contains a high amount of impurities. These impurities can include clay, sand, and other minerals. Poor lime is not as reactive as quicklime or hydraulic lime and is not suitable for use in many applications. It is sometimes used as a soil amendment or as a filler in concrete.
