4.10.4 CONCRETE COMPOSITION AND BATCHING TABLE
The volumes and/or weights of the individual components vary in relation to the breaking load and the product
characteristics, also considering practical experience.
The table below gives approximate values.
- Recommended operating cycle to produce workable concrete ( A ):
1 ) Pump in about 80-90% of the total quantity of water.
2 ) Add all the cement
3 ) Add all the gravel
4 ) Add all the sand
5 ) Add the remaining percentage of water.
- Approximate mixing time: 4-5 minutes
- Approximate total cycle time (aggregate loading, adding water, mixing, unloading): 15 minutes.
