Air content test is typically required for checking air-entrained concrete in areas where frost-related damage can occur. Air-entraining admixtures added to the concrete mixture create uniform and stable air bubbles in the fresh concrete. These voids will allow water to expand during freezing phase without damaging the hardened concrete. The measurement can be performed by water-column method (Type A to ASTM C231) or pressure method (Type B to ASTM C231).

Description
Introduction
The EN and ASTM standards describe two methods for the determination of air content of compacted fresh concrete: Water column type (eg. Our model 54-C0170/L) and Pressure gauge type (eg. our models 54-C0170/F 7 liters cap. and 54-C0170/D 8 liters cap). The air content is a very important parameter for the behavior of concrete to weathering and to verify the air content variation due to the use of chemical additives to increase the workability of concrete. All models utilize the principle of Boyle’s law.
Description
54-C0170/L Water column type, 5 l cap.
The water column type consists essentially of a stainless steel flanged cylindrical vessel with cover assembly, incorporating the measuring cylinder, pressure gauge and valves. Supplied complete with hand pump and calibration cylinder apparatus which is essential for adjustment to site barometric pressure.
The cylindrical vessel of all models can also be used as unit weight measure for fresh concrete for density determination.
