Compressive Strength of Concrete

In the UK concrete compressive strength tests involve the crushing of 150mm cubes. In the US and most of Europe the test involves crushing a 150mm diameter cylinder 300mm long. Cube results will generally be around 20% higher than cylinder results. Further details are included in our Concrete Cube Test post.
