The Versatile Use of Steel Decks in Construction
What is the main purpose of using steel decks in construction?
a. as forms only for reinforced concrete slab
b. as deck flooring which takes care of negative reinforcement of concrete slab
c. reinforcement for concrete slab
d. formwork for concrete slab that will be removed once the concrete achieves its maximum strength
Main Purpose of Using Steel Decks in Construction:
Steel decks are used as forms for reinforced concrete slabs and as deck flooring which provides the necessary negative reinforcement.
Steel decks are primarily used for two purposes, namely as a form for the reinforced concrete slab and as the deck flooring that handles the negative reinforcement of the concrete slab. The steel deck acts as a mould for the concrete when it is being poured and it also provides the key negative reinforcement for the slab. This is necessary because concrete, although it is strong in compression, is weak in tension.
The reinforcing rods in concrete are made of steel because steel's coefficient of linear expansion is nearly equal to that of concrete. Hence, when there are changes in temperature, the concrete and the steel expand or contract virtually at the same rate which prevents the development of internal stresses within the slab.
Steel is chosen for these applications due to its strength, durability, and ability to work in tandem with concrete without causing any issues. It is an essential component in modern construction practices, ensuring the stability and longevity of structures.
