Concrete Air Entrainment Meters
|
|
|
As Concrete air entrainment of air in limited percentage
improves durability of concrete and very low percentages deteriorate
it, measurement of air entrapped in freshly mixed concrete becomes
important. The use of chemical additives to increase workability
of concrete requires an air content check to be made. Air Entrainment
meters are used to determine air entrained in freshly mixed
concrete by pressure method. |
