VOLUME BATCHING OF CONCRETE – THEORY EXAMPLE

Jun 17, 2016  Step-1-Batching of cement. Cement is always measured by weight. Mostly it is used in terms of bags. One bag of cement weighs 50 kg and has a volume of 35 litres (or, 0.035m 3 ). Cement should not be batched by volume because its weight per unit volume varies according to the way the container is filled.

Concrete: Batching and Mixing Concrete Technology

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. These mixers are used on big concrete projects such as construction of dam etc.
