New Test Method to Evaluate Dynamic Stability of Self-Consolidating Concrete

Abstract

Stability is One of the Crucial Properties for Self-Consolidating Concrete (SCC). Dynamic Stability, Which Describes the Stability during Flow of Concrete, Remains, to Date, One of the Least Investigated Aspects of SCC Workability. a Novel Dynamic Stability Test, Tilting Box, is Proposed in This Paper. the Test Involves the Tilting of a Rectangular Box Numerous Times to Simulate Concrete Flow and Evaluating the Homogeneity of the Concrete with Increasing Flow Distance. Results Show that the Test Has an Adequate Repeatability and Sensitivity to Variations in Dynamic Stability Stemming from Changes in Mixture Design and Flow Conditions. Dynamic Segregation is Shown to Increase as the Flow Distance Increases or the Flow Velocity Decreases. Workability Characteristics Are Shown to Have Significant Effect on Dynamic Segregation.
