This document discusses properties of fresh concrete including consistency, workability, segregation, and bleeding. It defines consistency tests like slump test, flow test, and ball penetration test. Consistency refers to the wetness or stiffness of concrete, which is important for workability and preventing issues like segregation or bleeding. Workability refers to how easily concrete can be placed and compacted without defects. The document also discusses factors that affect workability and methods to improve it, like water-cement ratio, aggregate properties, and additives.
