|Normal vibrator 100mm.
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?|
|Parveen Kaushik said: (May 5, 2015)|
|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.

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

|From where you get this data?|
|Nabin Chandra Das said: (Jan 28, 2016)|
|How? Can you explain?|
|Engineer Shailza Kant said: (Jul 29, 2016)|
|For road construction 20-40.
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.

|Slump value of mass concrete without using vibrator should range in ______.|
|B. Karthik Raj said: (Feb 20, 2017)|
|Not understanding, How? explain it.|
|Udhay said: (Mar 16, 2017)|
|Not understanding, Could someone explain about it?|
|Ayaz Tareen said: (May 13, 2017)|
|Slump value of mass concrete without using vibrator should range in 6 to 7.5 cm.|
|Garry said: (Dec 1, 2017)|
|Right answer @Shiva.
It should be less than 25 mm for power driven vibrators.
And 25-50 mm for hand driven vibrators.

|What is the slump value for heavy section without using vibrator.|
|Ashu said: (Feb 24, 2018)|
|10;-25 vibrated concrete as per MS Sheety book.|
|Apurva said: (Dec 18, 2018)|
|Slump value less than 25 mm -> power driven.
Slump value - 25 - 50 mm -> hand driven.
Slump value - 50 mm -> Mechanical vibrator.
Slump value - 100 mm -> Normal vibrator.
|Surykant Chaudhary said: (Dec 28, 2018)|
|Vibrated concrete 12 to 25.
|Koushik Das said: (Feb 13, 2019)|
|25 - 50 mm = mechanical vibrator.|
|Relna said: (May 13, 2020)|
|What is the difference between a mechanical vibrator and a normal vibrator?|
|Bibhuti Baishya said: (May 21, 2020)|
|The mechanical vibrator is powered by a motor. Whereas normal vibration is carried out by a human using rods of suitable dia.|
|Shubham Siddharth Nayak said: (May 31, 2020)|
|Low workability- (25mm-50mm) slump- light reinforcement requires mechanically operated vibrator.
Medium workability- (50mm-100mm) slump- standard reinforcement requires hand-operated vibrator.
