Methods of Transportation of Concrete
Since the time taken within the transportation of concrete mainly depends on the initial setting time and therefore the need for workability at the location , it should be a design parameter.
For deciding appropriate admixtures in concrete to enhance specific properties, the transportation of concrete method is pre-decided beforehand .
Precaution: The homogeneity obtained at the blending time should be maintained while being transported to the deposition’s final place.
Methods of Transportation of Concrete:
Here, we discuss different transportation of concrete methods intimately . Let’s see.
Following are the various adopted transportation of concrete methods;
- Mortar pan
- Crane, Bucket, and ropeway
- Wheelbarrow or hand cart
- Belt conveyor
- Truck mixer and dumper
- Skip and hoist
- Chute
- Transit mixer
- Pump and pipe-line method
1. Mortar Pan:
Mortar pan may be a commonly used method in our country, especially for small-scale works, where the concrete is carried in small quantities. This method is more labor-intensive.
There are significantly fewer possibilities of concrete segregation, but this method exposes larger surface areas of concrete for dry conditions in thick members.
This leads to a considerable water loss thanks to more concrete exposure to an environment in weather.
2. Crane, Bucket, And Ropeway:
Crane and Bucket are mostly correct transportation of concrete equipment, especially for above-ground level. Cranes give more preference to high-rise construction projects.
Cranes are quick and versatile to maneuver concrete horizontally and vertically along the boom and enable concrete placement at the precise point. Those cranes carry buckets or skips containing concrete.

3. Wheel Barrow or Hand Cart:
It is generally used on the bottom level (i.e., construction and other similar structures. Segregation can occur if transportation of concrete is completed on rough roads over an extended distance. However, this vibration problem are often minimized if pneumatic tires are used.
4. Belt Conveyor:
it’s limited application within the concrete construction sector thanks to chances of segregation on steep slopes, roller points, and changes within the direction of the belt. Segregation also takes place thanks to the vibration of a rubber belt.
