It can form a dense and uniform concrete structure, and has better strength and durability than ordinary concrete. According to the relevant specifications and standards such as the "Technical Specifications for the Application of Self-Compacting Concrete" (JGJ / T283-2012), when the fresh concrete sample does not produce segregation, it is filled into the slump cone, and the material container is used to make the concrete mixture flow out evenly, and it is filled to the full without stratification. It should be completed within 1.5 minutes from the beginning of feeding to the end of filling, and no tamping or vibration is applied. In actual tests, it was found that it is difficult to accurately control the filling amount of the concrete sample. It is often the case that the slump cone is filled too much at one time or is not fully filled at one time, that is, it is difficult to fill it to the full without stratification.
