Abstract:Flowing concrete is characterized by high flowability, requiring only slight consolidation by vibrating and easy control in a plant. An experimental model structure using flowing concrete was made. Paper deals with placing capability on site and properties of hardened flowing concrete in the structure. Pumpability, flowability, and capability to fill forms were investigated for the fresh flowing concrete, and distribution of compressive strength, carbonation depth, cement content, air permeability, and water absorption were measured. Compressive strength of core samples taken from the model structure and standard cylinder specimens from the plant mixture were approximately 24 Mpa. The average estimated cement content was 333 kg/m 3 and the standard deviation was 15 kg/m 3 within a wall of 3 x 4.2 m. Measured carbonation depth was smaller in the freely flowed portions than in the upper portion of vibrated parts.
