Testing fresh concrete - Part 7: Air content - Pressure methods
Also Known As:
The DIN EN 12350-7 standard is focused on testing the air content of fresh concrete using pressure methods. The standard outlines two different methods for determining the air content in compacted concrete, specifically for concrete made with normal weight or relatively dense aggregate where the coarsest fraction of aggregates (Dmax) used is not greater than 63 mm.
However, it is important to note that the test is not suitable for use with concretes that have slumps less than 10 mm, as per the requirements outlined in EN 12350-2. Additionally, the standard specifies that neither of the methods described can be applied to concretes made with lightweight aggregates, air cooled blast-furnace slag, or aggregates with high porosity. This is due to the significant difference in the aggregate correction factor compared to the entrained air content in the concrete.
