Equipment for concrete construction and functions
Short answer
Crushers and batching plants produce and measure aggregate and cement. Mixers, transit mixers, pumps, vibrators, screeds, slip-form pavers and shotcrete machines mix, transport, place, compact, finish, pave continuously and spray concrete.
List the different types of equipments for concrete construction with their function. Explain briefly.
| Equipment | Function |
|---|---|
| Crusher and screens | Produce and grade aggregate |
| Batching plant | Measure cement, aggregate, water and admixtures by weight |
| Concrete mixer (drum, pan, twin shaft) | Mix the ingredients to a uniform concrete |
| Transit mixer (agitator truck) | Carry ready-mix concrete and keep it mixed in transit |
| Dumper / wheelbarrow / skip | Short-distance transport at the site |
| Concrete pump (truck or static, boom pump) | Pump concrete to height and distance through pipes |
| Crane, tower crane with bucket, hoist | Lift concrete in buckets to the work position |
| Belt conveyor, chute | Convey concrete horizontally and downward |
| Vibrators (needle, surface, form vibrator) | Compact concrete, expel air, and fill the form fully |
| Screed and power trowel | Level and finish floors and slabs |
| Slip-form paver | Continuous placing of road and canal lining concrete |
| Formwork systems and jacks | Hold concrete to shape until set |
| Curing equipment and sprayers | Keep concrete moist for strength |
| Concrete cutters and joint saws | Cut joints in pavement |
| Shotcrete machine | Spray concrete on tunnel and slopes |
Use: a typical building uses a batching plant or ready mix, a transit mixer, a pump or crane, and needle vibrators; for large pavements a slip-form paver is used. Choice depends on the volume, the placing rate, height, and distance of the pour.
