A mixture of cement, sand, ________ and water is known as concrete

• gravel

• mortar

• clay

choose the correct types of Portland Cement

• Ordinary Portland Cement (OPC)

• Rapid Hardening Portland Cement (RHPC)

• Slow Hardening Portland Cement (SHPC)

• Low Heat Portland Cement (LHPC)

• Sulphate – Resistance Portland Cement (SRPC)

Concrete can handle the higher compression stresses as compared to tension

• False

• True

Select some of the advantages of using concrete as construction materials

• Fresh concrete expands on drying and hardened concrete shrinks on wetting

• 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

• Lack of ductility, disadvantageous with respect to earthquake resistant design.

Select some of the advantages of steel as construction material

• Very strong in compression

• High ductility - Steel can undergo large plastic deformation before failure

• Highly suitable for prefabrication and mass production

• High fire resistant - high strength in fire if protected by paint.

• Steel can be reused after a structure is disassembled

Choose the common types of steel used in construction

• High Yield Steel

• Mild Yield Steel

• Soft Yield Steel
