What is the temporary force exerted by a device that introduce tension into a pre-stressing tendons?

• Driving force

• Tensile force

• Pre-stressing force

• Jacking force

It is a concrete used for structural purposes, including plain and reinforced concrete.

• Structural concrete

• Concrete

• Reinforced concrete

• Masonry

The ability of soil to allow water to flow through it.

• Osmosis

• Capillarity

• Seepage

• Permeability

Slump test is done in fresh concrete in order primarily to determine:

• Rigidity

• Elasticity

• Water content

• Workability

Inert materials in concrete which occupy more than 75% of the volume of the hardened concrete:

• Aggregates

• Gravel

• Sand

• Crushed Rocks

It is a method of pre-stressing in which tendons are tensioned after concrete has hardened.

• Precast Concrete

• Post Tensioning

• Pre-Tensioning

• Pre-Stressed Concrete

It is a material encasing prestressing reinforcement to prevent bonding of the prestressing reinforcement with the surrounding concrete, to provide corrosion protection, and to contain the corrosion inhibiting coating.
