Web1. Workability of Fresh Concrete. The diverse requirements of transportability, compatibility, mobility, stability, mixability, playability, and finish ability of fresh concrete mentioned above are collectively referred. To as workability. The workability of fresh concrete is thus a composite property. Webdetermine the pressure needed to pump concrete based on the desired flow rate, the diameter of the used pipes, the equivalent length of the pipeline (suggesting amplification factors for bends and reducers), and a fresh concrete property. Dependent on the origin of the chart, this fresh concrete property is either the slump [3] or the spread [1].
