Final answer:
Rebars material for residential construction are primarily made of steel, which is compatible with concrete and prevents thermal stress. Steel's unique properties like strength and corrosion resistance make it ideal for reinforcing concrete.
Step-by-step explanation:
The rebar used for residential construction is primarily made of steel. Steel is chosen for its compatibility with concrete due to its similar coefficient of linear expansion.
This compatibility is crucial as it prevents thermal stress in the structure. Steels are a staple in building construction and are comprised of iron with various amounts of carbon and other elements, which provides the material with its desired properties of strength, hardness, and resistance to corrosion.
Steel rebars reinforce the concrete by providing the tensile strength that concrete lacks, allowing for the creation of larger and more complex structures.
Rebar for residential construction is primarily made of steel. Steel is widely used in construction due to its strength, hardness, and resistance to corrosion. The reinforcing rods in concrete structures are made of steel because its coefficient of linear expansion is nearly equal to that of concrete.
