Self compacting concrete was first proposed by Japanese scholar Okamura in 1986.
Its excellent workability, flowability, and uniformity are significant characteristics of self compacting concrete (SCC).
SCC can use its own gravity to fill the formwork without compaction or vibration, and the hardened surface is relatively smooth and flat.
Coarse aggregates usually account for 28% to 35% of the volume of SCC, significantly affecting its performance.
The rheological properties of self compacting concrete are largely influenced by the characteristics of coarse aggregates, including shape, particle size, gradation, surface features, etc.
