The mixed concrete is placed into the cone through the top, a bar is used to compact the concrete and remove any air voids within the cone. The cone is then lifted clear. By laying the bar on top of the cone, it is possible to measure how far the concrete "slumps". A slump of approx 50mm is acceptable for C20 mix. This test is known as a "slump test". If you are mixing up several batches

The process of concrete hardening once it has been placed is called curing, and is a slow process. It typically takes concrete around four weeks to reach over 90% of its final strength, and the strengthening can continue for up to three years. Ensuring that the concrete is damp can increase the strength of the concrete during the early stages of curing. This is achieved through techniques such
