RRB Paper · Accepted Answer

According to IS 456-2000, the slump of a medium degree of workability of concrete if placed in heavily reinforced sections like slabs, beams, walls, and columns is 25-50 mm.

Workability:- All aspects of fresh concrete—those associated with several tasks, from the selection of materials to the final finishing—are collectively called workability. Workability of concrete can be defined as the ease with which a fresh- concrete mix can be handled from the mixer to the final structure.

Concrete Slump Test is a measurement of concrete's workability or fluidity. It's an indirect measurement of concrete consistency or stiffness.

Uses of concrete of different degrees of workability According to IS 456-2000

Placing Condition	Degree of Workability	Slump, mm
Mud mat, shallow section, pavement using pavers	Very low	0.70 – 0.80 (Compacting factor)
Mass concrete; lightly reinforced slabs, beams, walls, columns; strip footings	Low	25-75
Heavily reinforced slabs, beams, walls, columns	Medium	50-100
Slip formwork, pumped concrete	Medium	75-100
In situ piling, trench fill	High	100-150
Tremie concrete	Very high	150-200 (flow test as per IS 9103:1999)
