Concrete: Batching and Mixing | Concrete Technology

Batching of Concrete: In case of continuous mixers, the proportion of materials is done on the basis of volume batching. Thus concrete obtained by the mixer has less strength than obtained from batch mixers. Further control on mixing of ingredients in continuous mixer is also difficult. The cheapest and simplest method of cleaning the

Measurement Of Volume Of Aggregate In Batching

Volume Batching. 1:2:4 generally represents the ratio for M15 concrete. It is generally done by volume batching not by weight. After adding water to the dry mix, the gross volume of concrete reduces from the sum of individual volume of cement, aggregate and sand.
