Testing fresh concrete - Part 7: Air content - Pressure methods
Also Known As:
The DIN EN 12350-7 standard provides guidelines for determining the air content in fresh concrete using pressure methods. The standard specifies two methods for measuring the air content in compacted fresh concrete made with normal or dense aggregate, and with a maximum size of coarse aggregates not exceeding 63 mm.
It is important to note that this test is not suitable for concretes with low slump values of less than 10 mm, as outlined in EN 12350-2. Additionally, the methods described in this standard are not applicable for concretes made with lightweight aggregates, air cooled blast-furnace slag, or aggregates with high porosity. This is due to the significant aggregate correction factor in comparison to the entrained air content in these types of concrete.
