The rheology of fresh concrete has been working for many years, but only backwards a few years of research gives some more concrete results that could be used in the practice itself. Fresh concrete has to meet many criteria for hardening concrete to yield satisfactory results and have adequate properties after installation. The tests described in this paper attempt to establish that fresh concrete can be described using two constants. There is a tendency to make a certain model that for a certain type of business prescribes the minimum workability required and which will then provide the information for the mix calculation that will meet the other conditions. Based on the test, the use of vibration to install concrete is attempted, as concrete that is mounted by pumping behaves under the above conditions and many tests have attempted to link the complexity of the work for which the required workability has been determined. Many of the factors affect the workability of a concrete mix. Concrete mixing, transport and installation must retain the anticipated properties. The concrete mix must be stable and resist the occurrence of segregation and bleeding.
