Q: The bulk density of heavy mortar is more than
  • A. 50 kN/m³
  • B. 15 kN/m³
  • C. 500 kN/m ³
  • D. 115 kN/m³
Correct Answer: Option B - According to the bulk density of mortars in the dry states, they are classified into two categories– Heavy mortars–Heavy mortars are prepared with heavy aggregates, like quartz, they are called heavy mortars. Heavy mortars have bulk density of (15 kN/m³) or more Light weight mortars–These are prepared with porous sand and other fine aggregates and have a bulk density of less than (15 kN/m³)
B. According to the bulk density of mortars in the dry states, they are classified into two categories– Heavy mortars–Heavy mortars are prepared with heavy aggregates, like quartz, they are called heavy mortars. Heavy mortars have bulk density of (15 kN/m³) or more Light weight mortars–These are prepared with porous sand and other fine aggregates and have a bulk density of less than (15 kN/m³)
