Concrete structures are more costly than steel structures. Both types of material are the dominant materials that are used in building homes and offices.
I think you are talking about embedding steel rods (rebars) in concrete, right? This would make the concrete much stronger. It is called reinforced concrete, and you can make all sorts of structures with it, something that you can't do with ordinary concrete. Though, I am not even sure anyone is using non-reinforced concrete nowadays.
Concrete reinforcing steel is commonly used in bridges, buildings, skyscrapers and road construction. Reinforcing concrete with steel significantly increases its strength in an economical and safe manner.
how calculate steel in 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.
Because of the thermal compactablity of the steel the material is used in concrete
Generally, because concrete has massive compression strength and steel has incredible tensile strength. Combined, they make amazingly strong structures.
As per the civil engineering thumb rule, weight of steel for one cubic meter of concrete is 100kgs to 130 kgs for normal structures
Ans: The costly material in concrete is cement
Rust can weaken the steel reinforcement inside concrete structures, leading to cracks and structural damage over time. This can compromise the durability and stability of the concrete structure.
Apparatus used to bend and shape steel rod,especially used in the preparation of steel re-inforced concrete structures,eg concrete slabs and pillars.
They for strength for concrete structures. Concrete, like masonry, is strong in compression (forces downward on it) but not in tension (stretched out). Therefore the steel gives the concrete tensile strength.

Concrete structures are typically constructed using a mixture of cement, water, aggregates (such as sand and gravel), and sometimes additives or reinforcements like steel bars.
Yes , just the same as steel - otherwise the rebar would crack structures !

Steel reinforced concrete is concrete with rods of steel running through it.
