Q: The specific gravity of sandstone is
  • A. 2.65 to 2.95
  • B. 1.1 to 1.8
  • C. 1.8 to 2.65
  • D. 2.95 to 3.4
Correct Answer: Option A - Properties of compacted sand stone– • It is fire resistant and sedimentation rock. • Specific gravity 2.65–2.95 • Crushing strength varies 55-110 N/mm2 • Most suitable for road material. In the form of flag stone for paving, tile stone for roofing, natural stone for ornamental work and grit for heavy engineering works.
