Concrete Properties
Slump Flow (SCC)
// Definition
For self-compacting concrete (SCC), slump flow measures the spread diameter of fresh concrete after lifting the cone — typically 550-850 mm.
SCC requires no vibration and flows under its own weight. Measured by slump flow test (T500 time and final spread). Used for densely reinforced or complex sections.

Slump
A measure of the consistency and workability of fresh concrete, determined by the slump cone test. Reported in millimetres.
Workability
The ease with which fresh concrete can be mixed, transported, placed, compacted, and finished without segregation.
Superplasticizer
A high-range water reducer that can reduce water demand by 15-30%, allowing very low w/c ratios with high workability.
