Reasons why steel and concrete work effectively include

Together, these factors ensure that steel and concrete are used in structures with maximum efficiency, ensuring the stability and durability of the building.

The main reasons why steel and concrete work effectively together include the following:

Adhesion. There is a strong bonding force between steel bars and concrete, which allows them to coordinate deformation and work together under the action of external forces.
The temperature linear expansion coefficient is close. The temperature linear expansion coefficients of steel bars and concrete are relatively close, so that when the temperature changes, there will be no large internal stress between the two, thus avoiding damage to their bond.
Protective effects. The concrete protective layer prevents corrosion of the steel bars, which ensures the durability and stability of the structure.
Complementary physical properties. Concrete is excellent at withstanding pressure and relatively weak at tension. Steel bars are strong in tension. This complementarity allows the two to better utilize their respective advantages and jointly withstand various stresses when used together.
Chemical properties are similar. Steel and concrete have similarities in chemical makeup, which helps them form a stable unit.
Together, these factors ensure that steel and concrete are used in structures with maximum efficiency, ensuring the stability and durability of the building.
