Normal vibrator 100mm.
Mech vibrator 50mm.
Mech vibrator 50mm.

Is this correct @Anbu from where did you get data?

What is the difference between segregation and work ability? Can any body tell me regarding this?

Segregation means concrete cement slurry & fine aggregates &coarse aggregate collapsed & have no slump & after hardening no strength but workability is the checking the concrete how much time used after mixing.

Work ability can be carried after proper mixing then 1st fill the cylinder with out tamping weight it and again fill the cylinder with concrete and properly vibrate or tamping then weight it.
Compaction Factor = (wt of concrete wt out compact/wt of concrete with fully compacted)*100.
Compaction Factor = (wt of concrete wt out compact/wt of concrete with fully compacted)*100.

Slump is 0-25 mm for vibrate when use and 25-50 mm for mass concrete.

For road construction 20-40.
For vibrate 10-25.
Normal RCC work 80-150.
Mass concreting 25-50.
For vibrate 10-25.
Normal RCC work 80-150.
Mass concreting 25-50.

Segregation is defined as breakable cohesion between concrete particle.
Workability defined as ease (comfort) concrete in mixing, transporting and placing.
