Apr 13, 2017 Define reinforced concrete.Reinforced cement concrete is a composite material is made of concrete and steel reinforcement.The concrete may be assumed to work purely in compression whereas the reinforcement is predominately subjected to tension.For a large range of applications it is sufficient to consider the uni-axial response of either .
Apr 26, 2018 The life span of wooden sleepers is minimum (12 to 15 years) compared to other types of sleepers.They are liable to decay, attack of white ants, wear, spike killing, cracking, splitting, rail cutting etc.The concrete sleepers constructed of reinforced cement concrete are called RCC sleepers.RCC sleepers are the following two types .
At end of life, concrete can be crushed and recycled but the recycled material cannot be used for new building concrete.Steel: According to the British publication Building , 85% of steel is recycled, a process made easier by the fact that magnets are used in the process to sort steel.

Concrete is one of the most versatile and widely used as construction material throughout the world.Reinforced concrete structures has to withstand the environmental conditions throughout its life-span if properly prepared and placed.
Continuously reinforced concrete pavement (CRCP) is concrete pavement reinforced with continuous steel bars throughout its length.Its design eliminates the need for transverse joints (other than at bridges and other structures) and keep cracks tight, resulting in a continuous, smooth-riding surface that is virtually maintenance-free.
Cutting through concrete that is reinforced with steel is a difficult task.Steel is often used to provide stability for structural concrete, and it does a good job of this.However, it also means that if you need to cut the concrete you are likely to run into problems.Traditional blades will hit the steel and get chewed up or become blunt.
Dec 16, 2020 Its full name is reinforced cement concrete, or RCC.RCC is concrete that contains steel bars, called reinforcement bars, or rebars.This combination works very well, as concrete is very strong in compression, easy to produce at site, and inexpensive, and steel is very very strong in tension.Lifespan in corrosive environments, permeability .

Dec 23, 2010 Well when the O&M begins to cost more than the building is worth, it is no longer worth investing in O&M.Typically reinforced concrete structures, unless special purpose structures, are expected to have a operational design life of at least 50 to 100 years buildings tend to be on the high side, pipelines and other such facilities tend to be lower.
Early 20th-century engineers thought reinforced concrete structures would last a very long time – perhaps 1,000 years.In reality, their life span is more like 50-100 years, and sometimes less.Building codes and policies generally require buildings to survive for several decades, but deterioration can begin in as little as 10 years .
In RCC framed structure, the whole load is supported on beam and slab, where in load bearing structure, it is supported by masonry wall.The whole load of beam and slab is transferred through columns to footing in RCC structure, and masonry wall to masonry foundation in load bearing structure.
In the recent two–three decades lot of research relating to how to enhance the life of reinforced concrete structures has been carried out.As a result of which—it has been possible to design structures having service life span of more than 100 years.In concrete, cement paste is the primary active constituent.

Jun 27, 2018 Reinforced concrete or plastic pipe–it seems like a simple question, but in fact is not.The two materials have proponents and detractors in approximately equal numbers and there is little correlation of material to specific use, and size, by itself, is rarely a consideration.
Key Words: T-Girder, Reinforced cement, Bridge.Introduction Bridges are the life line of road network, both in urban and country zones.With fast innovation development, the commonplace bridge has been supplanted by creative practical structural system.One of these courses of action presents basic RCC framework that is T-Beam and Box Girder.
Life Span The life span of this roofing depends upon the installation technique and accuracy as well as the type of construction material used.According to the statistical reports, the average life span is about 40 years.The life span of this roofing can be further increased by providing an adequate and appropriate supporting framework.
Many concrete and sculptures (Masonry) worldwide is constructed with there is a great market for repairing and replacing these structures for the safe use and enhancing its life span.Lack of strength, stiffness, ductility and durability are the many conditions under which civil construction needs to be strengthened or rehabilitated.

RCC or Reinforced cement concrete is an amalgamation of concrete and steel.
RCC stands for reinforced concrete cement.It is a building structure made by combining the steel rod with cement concrete mixture.
RCC technology is a gods gift on the earth its life span is about to 100 years we cant say because invention of RCC design is less than 100 years so that we are not conclude the 100 years.Some of the structures such as dams old buildings life ia about 50 to 60 years they are very good in condition.
Reinforced cement concrete is an extremely popular construction material used for structural components of a building like beams, columns and slabs etc.One major flaw of RCC is its susceptibility to environmental attack.This can severely decrease the strength and life of the structures.
Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material in which concrete’s relatively low tensile strength and ductility are counteracted by the inclusion of reinforcement having higher tensile strength or ductility.In reality, their life span is more like 50-100 years, and sometimes less.
Reinforced concrete is a combination of traditional cement concrete with reinforcements (steel bar).This combination is made to utilize the compressive strength of concrete and tensile strength of steel simultaneously.In reinforced concrete, the components work together to resist many types of loading.

The Concrete Reinforcing Steel Institute is proud to honor five great concrete bridges built between 1990 and 2000.Each stands as a solid testament to concrete’s versatility, its cost effectiveness, and its durability.From arches to swing leaves, from foundation to superstructure, concrete is clearly a superior bridge-building material.
The corrosion of steel reinforcing bars is a predominant factor in limiting the life expectancy of Reinforced Cement Concrete (RCC) structures.Corrosion resistant Fibre Reinforced Polymer (FRP) bars can be an effective alternative to steel bars in this context.
The diameter of reinforcement bar commonly used in slabs are: 8 mm, 10 mm, 12 mm and 16 mm.According to ‘IS 456:2000’ (Plain and Reinforced Concrete – Code of Practice), the maximum diameter of bar that can be used in the slab should not be more than 1/8 th of total depth of slab i.In slab, maximum spacing of the main bar should be 3 times effective depth or 300 mm whichever is .
The life span of an above ground tank is limited while an underground tank, particularly in a durable material such as concrete is almost indefinite.Add to this the advantages such as temperature control and biological growth, and the economic advantages are significant.
The problem with reinforced concrete is that eventually the reinforcing will corrode, expand in size, and cause the concrete to crack.There can also be issues with the aggregates that are used.
The Reinforced Cement Concrete of beam size 1000mm x 150mm x 150mm was cast with the mix ratio of M25 grade of concrete.The water-cement-sand-aggregate weight ratio of the concrete mix was 0.
