The bleeding of cementitious materials corresponds to the settlement of the granular skeleton accompanied by the accumulation of water at the surface (bleed water).Part of this water (internal bleeding) remains trapped under the aggregates (sand or gravel) or the reinforcements.The excess of this trapped water can weaken the bond between the cement
