The maximum intake air restriction for the combustion air is traditionally a requirement from an engine manufacturer to the truck manufacturer. These requirements are for a new air cleaner pressure drop and a dirty air cleaner pressure drop. Typical values for a new air cleaner are 12 in. H2O (3 kPa) and 20 in. H2O (5 kPa) for a dirty air cleaner.

Air Entrainment versus Air Entrapment - NPCA

Because so many production variables can affect air entrainment, careful monitoring and trial batch testing are the foundation for proper air entrainment and a long service life for exposed precast concrete products. By Claude Goguen, P.E., LEED AP is NPCA’s director of Technical Services.

Concrete Curing Guide - Concrete Coatings

Air entrainmentof exterior concrete is a critical element affecting the durability of concrete sub-jected to freeze/thaw cycles. Too little air entrain-ment and the expansion and contraction of the concrete during freeze/thaw cycles will cause cracking and surface spalling. Too much air entrainment will cause the concrete to be lower strength ...

ACI , Structural Concrete Design

Air-entraining agents are probably the most widely used type of admixture. Minute bubbles of air are entrained in the concrete, which increases the resistance of the concrete to freeze-thaw cycles and the use of ice-removal salts. Waterproofing chemicals are often applied as surface treatments, but they can be added to the concrete mix.
