Q: The hydraulic property of lime is due to the presence of :
  • A. Magnesium Carbonate
  • B. Clay
  • C. Sulphates
  • D. Silica
Correct Answer: Option B - Properties of hydraulic limes– Hydraulic lime is obtained from limestone or kankar containing a very small percentage of free sand and soluble silica combined wih 10-39% of clay and magnesium carbonate, it also contains CaCO₃ these components impart the property of hydraulicity to lime.
