Why do we reinforce plain cement concrete?
Reinforcing schemes are generally designed to resist tensile stresses in particular regions of the concrete that might cause unacceptable cracking and/or structural failure.
Why plain concrete is not used for structural purposes?
Low tensile strength The first property makes plain concrete unsuitable for most structural applications, since even elements subjected to compressive stresses generally need sufficient tensile strength to inhibit buckling.
Why is reinforced concrete strong?
The reinforcing steel—rods, bars, or mesh—absorbs the tensile, shear, and sometimes the compressive stresses in a concrete structure. In reinforced concrete, the tensile strength of steel and the compressive strength of concrete work together to allow the member to sustain these stresses over considerable spans.
What is plain cement concrete?
Plain cement concrete is the mixture of cement, fine aggregate(sand) and coarse aggregate without steel. PCC is an important component of a building which is laid on the soil surface to avoid direct contact of reinforcement of concrete with soil and water. Fig 1: Laying of PCC.

Plain cement concrete is the mixture of cement, fine aggregate(sand) and coarse aggregate without steel. PCC is an important component of a building which is laid on the soil surface to avoid direct contact of reinforcement of concrete with soil and water.
What is plain concrete structure?
Plain concrete has no reinforcing materials added. The term plain concrete is used to describe any concrete mass used without any strengthening materials. Concrete is a combination construction material made of cement, ash, gravel, limestone, and granite.
Why is reinforced concrete so popular in building construction projects?
Reinforced cement has a compressive power that is very high. This support additionally makes it resist lots of strength. Structures built utilizing reinforced cement are more satisfied to resist states like quakes and thunderstorms. Concrete reinforced concrete is not any different and is a fire proof material.
Why is reinforced concrete a preferred construction material for high rise structure?
2.1. Currently, tall buildings are increasingly preferred to be made of reinforced concrete, since this material has the highest fire resistance, and its strength characteristics are close to the strength of steel.
What is plain concrete in construction?
Plain concrete has no reinforcing materials added. The term plain concrete is used to describe any concrete mass used without any strengthening materials. The physical properties of plain concrete are very similar to stone and include the ability to withstand great pressure.
