Where are Concrete Pipes?
Concrete Pipes are very common in sewage systems and underground water systems. Sewers carry the wastage from industrial or residential areas. It carries tons of suspended solid wastes along with the water. Concrete Pipes are durable, resistant to any kind of rust and sustainable towards any biological decay, these properties make it suitable to be a part of sewage systems. Storm Water Drains are pipes with large diameters and are meant for the flow of excess water from one area to another in order to alleviate the cause of flooding. During the situation of any storm, water can be moved through a high velocity.
Culverts are another major application of Concrete pipes. These are fitted in areas having large man-made areas such as flyovers, underneath roads, underground tunnels, etc. Being robust in structure and having high strength, they are known to bear heavy loads. Concrete making machines are therefore very useful in ensuring that the pipes being manufactured are high in tensile strength.
How are Concrete Pipes Manufactured?
Concrete Pipes are primitively composed of basic components that cement, aggregate that is sand and gravel, and water. All these ingredients are mixed differently in five forms and hence the manufacturing process gets categorized in five methods.
Centrifugal Method employs machines for making Concrete Pipes in a hollow structure. Concrete pipe making Machines cast them with the rotating mold giving a hollow shape thus making it compact and strong. Iron reinforcements can also be added sometimes. Concrete pipe making equipment inserts a steel pipe which compresses the mixture to make hollow shapes in the finally dried concrete pipes.
Besides the first method, in other methods like the Dry cast method, packer head method, the tamp entail method, pipe making machine uses a dry concrete mix and manufactures the desired concrete pipes through the standard technique of press rolling.
Another method, Wet casting method, machines for making concrete pipes use a high slump of wet cast concrete mix and it is highly recommended for making huge diameter pipes. Wet masses are introduced in the concrete pipe making machines to mold the input in a long pipe-like structure having an inner wall. The press rollers smoothen the inner layer and also applies an impregnating liquid medium. The build-up pressure is sufficient to enhance the permeability of the liquid medium to a depth of at least 10 mm.
The Bottom Line

They have been proved to be useful in holding any hazardous containment, sewage or drainage systems. Water supplies, Irrigation, etc. are the most remarkable systems for any cities across which have evolved in a much better way only after increased usage of Concrete PIpes.
Concrete batching plants are equipments used to combine sand or gravel , water , air, admixtures , fly ash, and cement to finally create concrete.
What are the main types of concrete batching plants?
There are two types. These are the wet and dry batching plant. There are plants containing both a transit mix chamber and a central mix side while having a common material storage point.
How does a dry batching plant operate?
The dry mix concrete plant is designed to accurately weigh out sand, gravel, and cement in weigh batchers. These are then discharged into a chute which then directs the mix to a waiting truck. In the process of discharging to the transit mixer, water is also volumetrically metered and discharged through the same chute. The materials are then agitated / mixed in a range of 70 – 100 revolutions on the mixer truck while in transit to the construction site.
How different or similar is the quality of concrete from the dry batching plant versus wet batching plant?
The dry mix plant has generally more break strength standard deviation and there may be some variations from load to load. This is brought about by differences in the mixing times, truck blade and drum conditions, traffic conditions and many other external factors.
The wet batching plant on the other hand, all loads are mixed at same station and under similar conditions and therefore it is much easier to get consistent quality.
What is the capacity of the dry batching plant?
This typically refers to the volume of concrete that can be processed in a period of time and is expressed in cubic meters. The batching plant capacity can also be referred to as the biggest factor or the main parameter considered in determining the price of a batching plant.
What are important advantages of the dry type concrete batching plant?
Storage time; the dry batching concrete can be stored for the longest time possible as no setting will occur. The maximum time the wet concrete mixture can be kept is not more than 24 hours; hence it must be utilized soonest possible.
Due to the large volume of production, the construction performance of the dry mix plant can be much higher than that of the wet mix. Materials used for mixing such as sand can be carefully screened to achieve the required fineness while the process is still ongoing, and the correct grade is easily achieved.
What are the important performance features of the dry concrete batching plant?
The dust during operation is much reduced and therefore environmentally safe.
The dry mixing plant can also be used in small batch mixes, while this is not possible for the wet mix concrete batches.
What are some of the latest innovations to the dry batching concrete plants?
Modern concrete batch plants now utilize computer aided control technology that assists in fast and accurate measurement of inputs and ingredients. Concrete performance is also highly dependent on accurate water measurements. The use of moisture probe during the water addition phase has also become an important feature in this equipment.
Transit mixer is a multipurpose device that used to transport concrete mortar from a concrete batching plant. The transit mixer is loaded with dry material and water; The transit mixer consists of a drum with a spiral blade which has the ability to move in two directions. The purpose of the drum is to ensure the concrete remains in the liquid state; while it rotates on its own axis. This type of mixer has multiple purposes and helps deliver concrete to several locations; especially remote locations.
Components of a Transit Mixer
The transit mixer has several components which is possible to apprehend from the name itself. It is basically a vehicle which has a rotating drum used as a mixer. It is possible for this drum to rotate while the vehicle is travelling. The purpose of the rotation ability is to ensure the concrete remains usable and of good quality. The main purpose of this type of machine is to be able to deliver the concrete to a working site (in most cases a remote site) while still maintaining its quality.
This machine has several components as listed below:
Detachable feed hopper
Crank chute support
Swivelling discharge chute
Additional extension chute

This machine consists of a supporting element that is an auxiliary frame. Discharge support along with a discharge channel is mounted to this auxiliary frame, at the same time a discharged feed hopper is also mounted to the discharge support with the help of a tubular frame. The swivelling discharge chute is vertically adjustable as per the requirement with the special support provided. This has an elliptical cross-section and is mounted to the discharge support by a reinforced double arm. It is possible to extend the discharge chute using additional extension chute. A gearbox with a drum bearing is bolted to the bearing pedestal; this is fixed on the auxiliary frame with the help of U-bolts. The mixer drum has mixing spirals that is supported by two rollers in discharge support; these are highly wear resistant.
The water pump is fanged to the gearbox. The mixing drum has a speed of 14/min, the water pump has a pressure of 3.5bars, and has the capacity to supply 250 liters of water per minute. A diesel engine runs the mixer and it is independent of the vehicle’s basic system. This engine too consists of a piston gearbox, thus allowing the operator to control the drum speed in a precise manner.
The mixing drum can be rotated either clockwise or anticlockwise and the speed can be controlled. This helps keep the concrete at the bottom of the mixer drum during transit while also maintain the optimal composition. Although the drum moves in both directions, the general rule is that while the transit mixer is in motion travelling on the road, it is necessary for the drum to rotate in a clockwise direction. However, when the concrete is being pumped the drum should rotate in an anti-clockwise direction. This type of rotation ensures optimal performance and also allows for the easy discharge of the concrete from the swivelling discharge tube.
A concrete transit mixer is essentially a truck that can transport concrete. The benefit of using this truck is that the process of mixing continues to take place even when it is in transit. It is highly durable and the concrete will stay in a good state for long, allowing the truck to cover large distances. These trucks also carry water and dry material to ensure the mixing takes place during transport keeping the concrete in usable condition. This is done with the help of a spiral blade present inside the drum of the truck.
