Methods of Batching Concrete - The Constructor

Methods of Batching Concrete 1. Volume Batching. In volume batching, materials are measured on the basis of volume. It is less precise method of batching; Measurement boxes or gauge boxes of known volume are used to measure materials. Cement is taken in the form of bags, where volume of one bag of cement (50 kg) is taken as 35 liters.

Concrete Batching - an overview | ScienceDirect Topics

Over a 6-month summer/autumn period, the energy consumption and production levels of six different concrete-batching plants were audited. The average CO 2 emissions due to batching per cubic meter of concrete produced were found to be 0.0033 t CO 2-e/m 3. Fig. 1.4 shows the contributions of each energy source to the total CO 2 emissions.
