Concrete Slump Variations at Site: How to Deal with it

2.3 Use of Air Detainer. An air detainer may be used to decrease air content and hence decrease the concrete slump. It is reported that a reduction of the air content by 1% leads to a decrease of slump by 1.27 cm. One should be aware that concrete with high air content is usually sent back to the concrete batching plant.

Concrete Batching - an overview | ScienceDirect Topics

Concrete batching is generally conducted at plants located at various strategic positions around a city or town to minimize transport time. Raw materials are mixed in elevated bins and placed directly into concrete trucks for final transport. This process is primarily powered by electricity, with small amounts of other fuels used on each site by small excavators used to move raw materials, etc.
