In the world of concrete, there are a slew of tests that exist for examining the substance’s current state. To determine the concrete’s quality, one of them must be undertaken. That being said, here are just some of the options that are available.
Slump tests are carried out in order to ascertain as to the material’s workability. Once the concrete has been batched, a fresh sample is taken for a slump test. Additionally, samples also undergo compressive strength tests. These assessments are conducted to make certain that the batched substances comply with the mix design before being released from the batching plant.
For a compressive strength analysis, three cylinder or cube samples are taken for examination, but depending on the specification, it could be two instead. If a concrete sample fails at 28 days, it may possess a slow gaining strength, but the necessary strength might be obtained once 60 days have passed.
Water permeability tests look into the concrete’s durability levels, with three cubes being taken from fresh concrete and tested according to the German Standard DIN 1048 at 28 days old. This variety of test is typically taken from substructure concrete elements that include retaining walls, water tanks, foundations and others.
At Churchill Concrete technology we prioritise those areas where concrete isn’t always visible, with basements, pillars and supporting walls being prime examples. The reason why an emphasis is placed on these locales in particular is that if they remain unchecked, substantial damages could follow. If you are worried about your own concrete, contact us immediately for survey and testing services.
