Bleeding occurs when freshly mixed concrete consolidates in a form. After the setting of concrete, formation of microstructure in hydrating concrete initiates on the consolidated frame. External bleeding water is excluded and the space occupied by internal bleeding becomes pore in hardened concrete. Understanding and furthermore estimation of bleeding are therefore important to assure the quality of fresh concrete. This paper provides a comprehensive model and advanced experimental setup for analyzing both external and internal bleeding. (C) 2013 Elsevier Ltd. All rights reserved.
