The answer is C.

Screeding: Striking off the excess concrete to bring the top surface up to proper grade is called screeding. It removes humps and hollows of uniform concrete surfaces.

Floating: It is the removal of all irregularities on the surface of the concrete that are left after screeding. It is done by wooden float.

Trowelling: Final operation of finishing be done after all excess water has evaporated by steel float to give a very smooth finish.

Finishing: Process of leveling and smoothing the top surface of freshly placed concrete to achieve the desired appearance.

In the case of roadwork, the final operation is BROOMING.

Finishing might be final operation for finishing floors.

The operation of removing humps and hollow uniform conrete surface is known as SCREEDING b.

Define screeding.

Floating: It is the process of removing the irregularities from the surface of concrete left after screeding.

What about floating?

TROWELLING : It is the final operation of finishing the concrete surface where smooth and dense surface required.

Can anybody define it?
