A Simple Guide to Concrete Cube Testing

The concrete is usually sampled after the 1 st metre of concrete has been poured to ensure a good sample is taken. As said in BS EN 12350-1, take a few samples throughout the pour for the best representation of the batch and make sure you take 150% of what you think you’ll need. The sample is taken and used to make the cubes.

Equivalent durability concept

According to EN 206-1: 2000, most batches are required to achieve the maximum w/c ratio and no batch may have a w/c ratio greater than the specified maximum w/c ratio plus 0.02. Provided a batch does not have a w/c ratio greater than the specified maximum w/c ratio plus 0.02, it is regarded as being of acceptable quality.
