  • Mild Yield Steel
  • Soft Yield Steel
  • Both A & B
Q.18
Select some of the advantages of steel as construction material

  • Highly suitable for prefabrication and mass production
  • Steel can be reused after a structure is disassembled
  • All Of above
Q.19
Select some of the advantages of using concrete as construction materials
  • Concrete expands and contracts with the changes in temperature.
  • Easy to disintegrate by alkali and sulfate attack
  • Needs another material to reinforce it against excessive shear and tension
