WHAT IS VOLUME BATCHING OF CONCRETE AND HOW IT IS

Apr 10, 2014  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.
