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.

May 29, 2010  Here is another important note: Most mixers’ batch capacities are actually about 67 percent (or two-thirds) their total volume. Therefore, if a plant needs to batch 1 yard of concrete, the mixer’s total volume would need to be 1.5 cubic yards. It is important to know how a mixer is rated, either by batch volume or total volume.
