This paper describes the fall characteristic of the mixture materials in vertical tube. In this paper, the mixture materials were made by clay and converter steel-making slag. As time passed, the cohesion of the mixture materials was growing up, and we measured it by the cylinder flow test. We experimented about the dumping the mixture materials into the vertical tube.
As the result, we found that the mixture materials had three fall conditions which depended on its flow value, and became three accumulated shapes, and that the turbidity from clay and pH from converter steel-making slag were influenced by their fall condition and accumulated shape.
