What is the property of RCC?

Concrete is good for resisting compression but it is also very weak in preventing stress. Therefore reinforcement will be provided in concrete where tensile stress is expected. The best reinforcement is steel, because steel has a high tensile strength and the bonds between steel and concrete are good. Since the elastic modulus of steel is higher, the resistance by steel is higher than that of concrete for the same expansion.

In the tensile zone, however, a shortage of hair in concrete is inevitable. Reinforcement is usually in the form of mild steel or ribbed steel bars of 6 mm to 32 mm diameter. A cage of reinforcement is made according to the requirements of the design, it is placed in the work of the form and then the green concrete is poured. Form work will be removed once the concrete has hardened. The combined material of steel and concrete is now RCC. Acts as a structural member and can withstand stress as well as stressors.

 

Properties of R.C.C./Requirement of Good R.C.C.

 

1. It should be able to resist the expected tensile, compression, bending and shearing forces.

2.It should not show excessive deflection and spoil the need for serviceability.

3. Reinforcement should have proper covering, so that corrosion is prevented.

4. Cracks of developed hair should be within the permissible limits.

5.It is a good fire resistant material.

6.When it is fresh it can be molded to any desired shape and size.

Reinforced Cement Concrete (R.C.C )

Reinforced Cement Concrete (R.C.C )

 

RCC is the most integral component of 21st century civil engineering, reinforced cement concrete. The RCC has elevated the world to a higher level.

 

What is Reinforced ?

 

According to the Oxford Dictionary, reinforced means "make it strong." So we make concrete with steel strips.

What is cement ?

 

Cement is a well-known building material as a mandatory space occupied in construction work.

 

China is currently India's second largest cement producer.

 

What is concrete ?

 

Inorganic materials, known as common concrete cement, are mixed with water and combined with natural stone piles and natural stones that can be boiled or crushed.

Why the combination of rust and material?

 

a)The co-efficiency of linear expansion of concrete and steel is almost the same. Therefore no internal stress is established in the reinforced concrete due to the change in temperature. ( Materials expand or contract when subjected to change in temperature .... An average value for the co-efficient of increase in light of concrete is about 10*10^-6/c, & steel for 7.2*10^-6/c. )

 

b) The coating of cement on the steel bars protects them from rust and does not create adverse chemical effects.

 

c) The surface of the steel rod is set very quickly while gripping concrete. Therefore, concrete can transfer stresses to the reinforcement that cannot be resisted.

Advantages, Disadvantages and uses:

 

Advantages: Reinforced concrete has the following advantages:

1. It will not rot or rot and will not be attacked by termites.

2. It is economical in terms of cost.

3. Almost no moisture is passed.

4. Its constituents are easily available.

 

5.It can be easily molded into any shape.

6. It is durable.

 

7. The structural member can be made with any desired strength.

 

Cons: Cons of reinforced concrete-

 

1. High initial cost,

 

2. Heavier than steel construction,

 

3. Skilled supervision and workmanship required,

 

4. Involves additional cost of form-work,

 

Uses: Reinforced cement concrete is commonly used for the construction of the following:

 

1. Slabs,

 

2. Lintels,

 

3. Beams,

 

4. Columns and their footings,

 

5. Foundations,

 

6. Precast or cast-in-situ concrete piles etc. 

Reinforced concrete

 

Reinforced concrete

Reinforced concrete (RC) (also called reinforced cement concrete or RCC) is a composite material that is resisted by the inclusion of reinforcement with a relatively low tensile and low tensile strength or ductility. Although reinforcement is not usually necessary, steel is a reinforcing bar (ribber) and is usually passively embedded in concrete before sets of concrete.

Description

Reinforcement plans are typically designed to withstand tensile stress in specific areas of concrete that can lead to unacceptable cracking and / or structural failure. Modern reinforced concrete may contain different reinforcing materials made from steel, polymer or alternative composite materials with or without a combination of rebar. Reinforced concrete can also be permanently tensioned (concrete in compression, reinforcement in tension), in order to improve the behavior of the final structure under working loads. In the United States, the most common methods of doing this are known as pretensioning and post-tensioning.

For a strong, ductile and durable construction, the reinforcement must have at least the following properties: -

•          High relative strength

•          High toleration of tensile strain

•          Good adhesion to concrete, regardless of pH, humidity and similar factors

•          Thermal compatibility, which does not cause unacceptable stress (such as expansion or contraction) in response to changes in temperature.

•          Environmental durability of concrete, regardless of corrosion or sustained stress, for example.

What IS CULVERT

A small bridge having total length of 6m or less than 6m between the faces of abutments is known as culverts. Culverts are a permanent drainage structure mainly constructed to carry roadway or railway track over small stream or channel.

• Types of culverts

1. Arch culverts

2. Open or slab culverts

3. Pipe culverts

4. Box culverts

1. Arch culverts

The culverts having its superstructure consisting of one or two arches constructed of any suitable masonry is known as an Arch culverts.

 In these culverts segmental arches consisting of brick masonry, stone masonry or concrete are commonly used. These arches can be easily and cheaply constructed. The abutments and piers or these arches are constructed sufficiently strong to take their lateral thrust arch culverts are specially suitable where the approaches are to be constructed in cutting.

2. Slab culverts

The culverts, having its superstructure consisting of RCC slab which carrier the bridge floor, is known as slab culverts.

 In this type of culverts, the RCC slab of suitable thickness is provided as simply supported over abutments and piers which are constructed of any suitable type of masonry. Slab culverts are suitable where the bed of the canal stream is sufficiently firm. These are provided up to maximum span of 3m.

3. Pipe culverts

The culverts which consists of one or more pipes placed side by side over a concrete

Base below the embankment of a roadway or railway track is known as pipe culvert.

In this type of culverts, one more pipes consisting of cast iron, steel or RCC are held in positioning over a concrete base by fixing their both the ends into masonry walls. 

In pipe culverts , generally , more than one pipe , of diameter not less than 30 cm is  used. However, their exact number and diameter depending upon the discharge and heights of the bank. As far as possible the gradient of the pipe should not be less than 1 in 1000. Pipe culverts are suitable where the flow if water in the stream is very small.

4. Box culverts

                   The culverts consisting of one or more numbers of rectangular or square opening ,                                having  their floor and top slabs constructed monolithically with abutments and pier, is                         known as box culverts.

                  Box culverts are usually constructed of precast rcc slabs. Small span box culverts may be                  constructed of stone slab, supported masonry abutments, with brick or stone flooring.                             These  culverts provided the least interface to traffic during construction.

                 Box culverts are mainly constructed where the soil is soft and the load has to be                                  distributed  over a wider foundation area. This type of culverts can be conventionally used                   for a single span of 3 m or for double span of 6m.
