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).

Weigh Batching

Aggregate batching is simpler than that of cement because of a more constant natural flow rate. In fine aggregate, the moisture content does effect the flow rate. This is unimportant because volume, not weight, is the desired quantity. The volume is found as a function of the weight.

Determining Moisture in Aggregate for Mix Proportioning ...

Mar 01, 1986  The difference in weight represents the total moisture content of the aggregate. For making batch calculations it is handiest if moisture has been calculated as percent of the SSD weight of the aggregate. The total moisture measured in the test represents both the free moisture and the moisture that the aggregate absorbs.
