The design of concrete with specified properties for an application is not a new science, but it has taken on a new meaning with the wide use of high performance concretes (HPC). The following properties are related to fresh concrete: "ease of placement" and "compaction without segregation." The term, ease of placement, covers various other properties of fresh concrete that are called: workability, flowability, compactibility, stability, finishability, pumpability, and/or consistency. These words are often used interchangeably without a definition based on fundamental measurements of properties. Several attempts were made to better relate fresh concrete properties with measurable entities. Some researchers treated fresh concrete as a fluid and used the fluid rheology methods to describe concrete flow. This approach, the most fundamental one, is reviewed in this paper.
The main topics that will be addressed are:
