Adjusting Air Entrainment| Concrete Construction Magazine

Feb 17, 2009 · When air entrainment is added to concrete, there is some effect on slump, and compressive strength is reduced by about 500 psi in a standard 6-bag (564-pound) mix. There are two kinds of air in concrete: entrapped and entrained. Entrapped air is a result of the mixing process. As concrete is being mixed about 1.5% air becomes entrapped.

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.
