Reinforced Concrete Tubes (RCC)
Reinforced concrete tubes with strength of up to the Diameter of 1000 m are specially reserved for the SSI sector Manufactures. Drainage, irrigation, sewerage, and culverts are the areas where these pipes are most commonly used.RCC pipes are made from the materials such as sand, mild steel, bars, cement and HT rods.
Classification of RCC pipes
There are two types of RCC pipes. They are
- Pressure pipes
- Non pressure pipes
Demand for Reinforced Concrete Pipes
Nowadays the demand for RCC pipes is more and more than before.RCC pipes are bulky purchased by the departments such as National Highways, Irrigation department, Public Health Engineering Department, Forest Department etc. Moreover many civil contractors who are undertaking the works of public sectors and government are also the mass purchasers of RCC pipes. Currently, government introduces some schemes for farmers such as water supply and irrigation schemes so the demand for reinforced concrete pipes is increasing.
Short view of manufacturing process
The reinforced cage is initially fixed to the cage winding machine by the method of hand processing. The cage pipe is placed in the mold and it is lifted up and mounted in horizontal turn unions. It rotates using a driving shaft with variable speed .The adjustment slows down the rotation initially and then accelerates Increased. The RCC pipes are prepared from the mixture proportionately 1: 2: 5: 2: 5 for cement stone, metal and sand, respectively. During rotation the axes spread evenly inwards. The time of completion depends on its strength (diameter) and its class. The mould holds the pipe for 24 hrs. The next day the pipes are taken from the mould and immersed in water in a curing tank for 15-20 days depending on its class. Then the specimens are taken for the following tests:
- Hydrostatic pressure test
- Three edge bearing test
- Absorption test.
Pros of Reinforced Concrete
- Compare to other materials for construction, it has high compressive strength.
- Because of the reinforcement provided, reinforced concrete can also withstand a better tensile stress.
- Reinforced Concrete ‘s weather and fire resistance is fair
- Compare to other building systems, the durability of reinforced concrete buildings is better.
- Initially, reinforced concrete as a liquid material can be shaped into infinite shapes.
- Its cost of maintenance is very low.
- The most economical construction materials are concrete, which is more rigid in structure, i.e. footings, piers , and dams.
- It is widely used in precast structural elements as it can mold reinforced concrete in any shape required. It provides rigid members with obvious deviations.
Cons of Reinforced Concrete
- Mixing, casting, curing are the steps of reinforced concrete so it may affect its final strength.
- The forms that are used for casting are of higher cost.
- Shrinkage causes cracking and loss of strength.
