Q: The cross sectional area of cubes used in testing of compressive strength of cement is
  • A. 50 cm²
  • B. 100 cm²
  • C. 225 cm²
  • D. 250 cm²
Correct Answer: Option A - Proper size of mould for testing compressive strength of cement. • Compressive strength of cement is the capacity of taking compressive loads of cement • It is determined by compressive strength test on mortars compacted by a standard vibration machine • Mould size = 7.06 cm ×7.06 cm × 7.06 cm • Cross section area = 7.06 cm ×7.06 cm = 50 cm²
