Abstract:
The use of highly fluidized concrete is becoming more practical and its applicability has been verified through various methods of concrete construction. However, properties of the concrete in its fresh state differ greatly from those of conventional concrete and a suitable quality control system needs to be established to assure the quality of structures. Four quality control procedures are proposed, based on data obtained from actual construction sites: controlling the properties of fresh concrete, controlling the unit water content, confirming the absence of initial defects in placing, and assurance of no aggregate segregation.
