Q: Which of the following could be the specific gravity of stone to be used as a building material?
  • A. 2.7
  • B. 1.7
  • C. 1.9
  • D. 1.3
Correct Answer: Option A - Specific weight of stone which are used in construction not taken less than 2.7. Unit weight of stone are much greater then strength is more. The amount of CaCO₃ and MgCO₃ are more than acidic effect increases rapidly. Specific weight porous rocks have 2.4 or less than 2.4.
