material dry mix.
C. Placement.
- As preparation, work location of concreting cleared from garbage, wood cutting, bend
rat, nail and other garbage with vacuum cleaner, compressor and or water.
-
Form work coated internally with mould oil till covering all surface. Leakage of form
work been checked and repaired. Construction joint with concreting before all have
been coating with cal bond or cement water and also form work free from water pond.
Dredging and Embankment of River
Before concreting instruction, all permission the needed have been managed and
agreed by directors / owner and work supervisor.
-
For the Concrete of ready mix, concreting done by mechanically, from truck mixer pass
gutter. Concrete shall not be dropped freely into form work heights greater than 150
cm. So it’s not happened dissociation between the weight aggregate with concrete
pasta, (segregation).
-
Compaction helped with adequate selected vibrator type mechanically in number.
Vibrator pipe inserted into the wet concrete vertically so that it penetrate to the bottom
of the freshly placed concrete and provides consolidation throughout the full depth of
section and it’s not to happened air pocket. Vibrator do not hit shutter or bar except
cover of concrete.

Considerations for producing a good concrete work
- The quality of the concrete depends a great proportion of the materials
used such as cement, sand, aggregate and water
- Lack of cement in the concrete mix causes less qualified and weak
- Too much water leads to poor concrete quality
- It is important to measure and add gravel and sand separately to create a
quality solid concrete
- Always use a clean gravel
