It deals with the tension and compression of the concrete. Concrete is a really great material when in comes to compression. It has a high strength in compression but little in the way of tension. You can test this for your self. Get a small unreinforced piece of concrete and pull it apart it ( put it in tension) and it breaks fairy easily. Now, try pushing together (put it in compression) and it doesn't break anywhere near as easily, if you can break it at all. Steel is the opposite. It has more strength in tension than in compression. Putting steel bars in concrete allows you to have good strength in compression and in tension. In an easy way to understand it and get the general idea, when the reinforced concrete is under tension, the steel bars take over, and when the reinforced concrete is under compression, the concrete takes over.

answ2. Concrete is strong in compression, but weak in tension.
In a well designed reinforced beam, the compressive strength of the concrete will be matched to the tensile strength of the reinforcing.
The outer 25mm or so of concrete outside the reinforcing is not counted in the calculations, for it can experience tension!

Why are iron and certain other transition metal are used in construction instead of the alkali metals?
Iron has more important mechanical properties.
Why is iron used to make girders for building?
Because Iron is a strong metal that is easily smelted and relatively plentiful in the earth crust.
Most used metal?
This metal is iron.
What is the best metal for construction?
lead and silver is the best. This is because Lead is best for water pipes. Iron is also good as it can be used for hammers and nails. Silver is the best heat conductor.
What silver white metal is used in airplane construction?
Aluminum
A major metal used in construction?
Iron.
What the most widely used building metal?
This metal is iron.
What metal is used in construction?
If your question is about the structural frame of the building then it is steel
What are some uses for iron metal on a construction site?
Iron is rarely used in in its pure form for construction due to the ease with which it corrodes. However, it is frequently used to make steel which is then widely used on construction sites for things like girders.
Why are iron and certain other transition metal are used in construction instead of the alkali metals?
Iron has more important mechanical properties.
Where can one find metal building construction?
Metal buildings might be found in many places, including one's own backyard in the form of a metal shed. More often though, they are used for industrial purposes. Metal building construction specialists include Meuller Inc. and Allied Buildings.
Why is iron used to make girders for building?
Because Iron is a strong metal that is easily smelted and relatively plentiful in the earth crust.
What are construction tools used for?
Construction tools are used primarily in building construction.
Where does metal come from and what is it used for?
Metal ores are found underground, and are mined to produce metal. Metals have many different uses that are specific to the individual metal - copper is used for wires due to its good conductivity, iron is used for magnets as it is magnetic, and steel (analloy consisting mostly of iron) is used for building as it's very strong.
How is iron used in building materials?
Iron is the basic ingredient (usually 95% plus) of every alloy of steel, the most basic construction material there is for buildings, cars, appliances, and what-have-you.
What are constructions used for?
Construction tools are used primarily in building construction.
What do you use aluminuim for?
Aluminum ranks as the second most used metal due to its versatility. It is used in transportation, building and construction, packaging and in electrical products.
