High workability concrete
WebA high air content is usually specified in concrete pavements to protect against freeze-thaw damage, and can partially offset the workability issues with using angular aggregates as explained above. However too much entrained air can lead to a mixture which is sticky and difficult to finish, as well as reducing the strength.
