Concrete is basically strong in compression butWEAK IN TENSION this limitation can be compensated by providing steel as being strong in tension it takes the tensile forces and make section safe in tension.......moreover both concrete and steel have same coefficient for thermal expansion so there are no additional stresses due to temperature change.
Steel reinforced concrete is concrete with rods of steel running through it.
The steel rods are there to strengthen the concrete - making it reinforced concrete.
how calculate steel in concrete
The basic matetrials were steel and concrete.
Concrete is much more fire resistant. This is shown by the design of reinforced concrete structure where the steel is placed within the concrete. A major reason is that the concrete protects the steel from any fire. Steel only construction requires the steel to be covered in a fire protection material.
No, it is not recommended to pour concrete directly onto steel bars painted with red oxide primer. The primer may prevent proper adhesion between the concrete and the steel, leading to a weaker bond and potential structural issues. It is important to remove any paint or primer from the steel bars before pouring concrete to ensure a strong and durable connection between the two materials.
depends on the bridge type really. most are steel and concrete.
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
Concrete is unpredictable compared to steel...
Mainly re-enforced concrete (concrete that's been set around steel rods). The cables are made from many long strands of steel.
