Air entrainment tests.
Where Air entrained concrete is specified or supplied (often abbreviated to Aea on supplier’s delivery tickets) it is important the correct % is achieved. Too high and the concrete compressive strength will be compromised and a higher risk of delamination, too low and the durability of the concrete will be compromised.
BS EN 206 stipulates that when an air entrained (Aea) concrete is used it must be tested daily, it is also important to continually monitor the air content during large external works.
Some ready mixed concrete companies will produce air entrained “branded” grades of concrete that our not covered bs BS EN 8500. These should not be excluded from air entrainment testing.
Whilst this test should be carried out by the concrete supplier, we recommend independent testing to ensure results are correctly reported.
We can quote for a single visit to conduct a slump, Air, temperature and 4 set compressive test or part or full day monitoring.
Our Air entrainment tests are carried out in accordance with BS EN 12350-7.
