Q: The hydraulicity of the hydraulic lime is mainly due to____.
  • A. Calcium oxide
  • B. Clay
  • C. Sulphur
  • D. Water
Correct Answer: Option B - It is sometimes observed that lime sets in damp places or under water where there is no free access of air. This property of lime is known as hydraulicity. Hydraulicity of lime depends upon the amount of clay and the type of clay present. Hydraulic lime has a great hydraulicity as it is obtained by bushing limestone containing lot of clay.
