It has been reported that, depending on the material used, batches of concrete having the same slump value behave differently when vibrated. It is therefore to be expected that batches of concrete having the same slump value and containing the same amount of powder will have different properties depending on the material used. However, these batches of concrete are treated as concrete of the same quality since, at present, no alternative test method has yet been established as a substitute for the slump test. This study proposed new simplified experimental methods for vibration properties of fresh concrete. By using these methods, the vibration characteristics of fresh concrete containing fly ash (FA) and containing a large amount of cement were exhibited.
