The document outlines the 8 key steps in the concreting process: 1) Collection of ingredients, 2) Batching ingredients by volume or weight, 3) Mixing ingredients homogeneously, 4) Transporting concrete via pans, wheelbarrows, trucks or conveyors, 5) Placing concrete in formworks, 6) Compacting concrete using tamping rods or vibrators, 7) Finishing concrete through screeding or troweling, and 8) Curing concrete through water sprinkling, ponding, steaming or covering to improve durability and reduce shrinkage.
1. Concreting
-Process of making concrete .
1. Collection of Ingredient.
- Collect all the ingredient that is required for making concrete.
Where we should store the ingredient ?
- No moisture will be contact with the ingredient.
2. 2. Batching of ingredient.
-Measuring of ingredient that is required for making concrete.
i )Volume batching
ii)Weight batching
3. Mixing of ingredient .
- The aim of mixing of concrete is to produce homogenous ,
consistent and uniform coloured concrete .
i) Hand mixing
ii) Machine mixing
3. 4. Transporting the concrete.
-Transfer the concrete from the place where it is mixed to the
form work.
i) pan
ii) Wheel barrow
iii)Truck mixer
iv)Belt conveyor
v)Pumps
5. Placing of Concrete .
- Process of fill the formwork with the concrete .
4. 6. Compaction of Concrete .
- Reducing the air voids that is present in freshly mixed
concrete at the time of placing & make the concrete dense .
i) Tamping rod .
ii) Vibrator.
7. Finishing of concrete .
-Process of levelling , smoothing , compacting of freshly and
recently placed concrete to provide desired appearance .
5. Method of finishing of concrete .
i) Screeding
ii) Trowelling
8. Curing of Concrete .
- The operation of maintaining the temp. of freshly placed
concrete for some definite period after placing the concrete for
sufficient hydration.
Objective of curing .
i) Improve weather resisting quality .
ii) Durability .
6. iii) Impermeablity .
iv) Reduce shrinkage .
Method of Curing.
i) Sprinkle of water.
ii) Ponding method .
iii) steam method .
iv) Covering concrete surface with wet sack.
