workability level for different concrete elements in batch plants

Workability of Concrete - Tests & Factors Affecting Workability

It is the most common method for measuring the workability of freshly mixed concrete. It can be performed both in lab and at site. Uniformity of the concrete regarding workability and quality aspects can be assessed from batch to batch by observing the nature in which the concrete slumps. It is not very suitable for very wet or very dry concrete.

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.
