Various Methods of Transporting Concrete

Ready mix concrete should be transported to the construction job site in a certain time. After hundred of hundred years of development of the concrete technology, there are a wide variety of equipment used for transporting concrete, from hand tools to heavy industrial machinery. The following article will list some methods and analyze their pros and cons for your reference.

  1. Mortar Pan

    mortar panMortar pan is be used for small quantities concrete transporting in some countries. This method exposes greater surface area of concrete for drying conditions. To some extent, this method also nullifies the segregation, particularly in thick members. And it also may cause greater loss of water, particularly, in hot weather concreting. Note that mortar pan must be wetted to start with and must be kept clean.
  2. Wheel Barrow

    Wheel barrows is another normal way used for transporting concrete in ground level. This method is employed for hauling concrete for comparatively longer distance as in the case of concrete road construction. If concrete is conveyed by wheel barrow over a long distance, on rough ground, it is likely that the concrete gets segregated due to vibration. In order to avoid this, wheel barrows are provided with pneumatic wheel.
  3. Crane, Bucket and Rope way

    concrete crane bucket and ropeA tower crane and bucket is one of the right method for transporting concrete above ground level. It is a familiar way in medium and large sites owing to the crane can handle concrete in high rise construction projects. Apart from it, cranes are fast and versatile to move concrete horizontally as well as vertically along the boom and allows the placement of concrete at the exact point. Cranes carry skips or buckets containing concrete. Skips have the discharge door at the bottom, whereas buckets are tilted for emptying. For a medium scale job the bucket capacity may be 0.5m³. Rope way buckets of various sizes are adopted for Concrete works in valley, Construction work of the pier in the river, Dam construction.
  4. Truck Mixer (Transit Mixer) and Dumpers

    truck mixerTruck Mixers and dumpers or ordinary open steel-body tipping lorries can be used for large concrete works to be placed at ground level particularly with the advantages of travelling to any part of the work. Compared with the jubilee wagons that require rail tracks, they have much advantage. Transit mixer is one of the most popular equipment for transporting concrete over a long distance particularly in Ready Mixed Concrete plant (RMC). In one, mixed concrete is transported to the site by keeping it agitated all along at a speed varying between 2 to 6 revolutions per minute. In the other category, the concrete is batched at the central batching plant and mixing is done in the truck mixer either in transit or immediately prior to discharging the concrete at site. Dumpers are of usually 2 to 3 cubic metre capacity, whereas the capacity of truck mixer may be 4 cubic metre or more.
  5. Belt Conveyors

    Belt conveyors is also can be used to transport concrete, but is has a very limited applications because the tendency of the concrete to segregate on steep inclines, at transfer points or change of direction, and at the points where the belt passes over the rollers. Belt conveyors can place large volumes of concrete quickly where access is limited.
  6. Chute

    wheel barrow and concrete chuteChutes are adopted for transporting concrete from ground to a lower level. The sections of chute should be made of or lined with metal and the surface should have same slope not flatter than 1 vertical to 2 and a 1/2 horizontal The lay-out is made in such a way that the concrete will slide evenly in a compact mass without any separation or segregation.
  7. Skip and Hoist

    Skip and hoist are often be used as one method for transporting concrete vertically up for multistorey building construction (3 to 4 floors). At the ground, the skip will be directly fed by the concrete mixer and then it travels up to the place where concrete is required. At that point, the skip discharges the concrete automatically or on manual operation.
  8. Pump and Pipeline

    Concrete PumpPumping of concrete is universally accepted as one of the main methods of concrete transportation and placing. Starts with the suction stroke for suck the concrete inside the pipe. It has a piston which moves forward and backward to have suction and delivery of concrete. Adoption of pumping is increasing throughout the world as pumps become more reliable and also the concrete mixes that enable the concrete to be pumped are also better understood. The modern concrete pump is a sophisticated, reliable and robust machine.

Owing to over 30 years of manufacturing experience in concrete machinery field, Camelway Machinery can provide the whole set of equipment for concrete mixing and transporting including concrete mixer, concrete batching plant, truck mixer, concrete pump, etc.
