Centrifugal concrete products are manufactured using specific technology that changes the concrete proportion during consolidation. The bleeding of water reduces the water-to-cement ratio and increases the compressive strength of concrete. This affects the strength of the concrete determined on conventional casted cylinders, centrifuged hollow cylinders, and drilled cores from piles.
