Concrete Slump Chart

The concrete slump workability chart outlines different concrete mixes and their appropriate applications based on slump, or workability. Very dry mixes with a 0-1” slump are best for paving machines, while mixes with a 1-2” slump work well for foundations and pavements consolidated by hand. Medium workability mixes of 2-4” slump can be manually placed or consolidated and are suitable for reinforced flat slabs and walls. Highly workable 4-7” slump concrete is preferred for pumping and congested reinforcement.

Concrete Slump Workability Chart

Slump Workability Application

Very dry mixes in paving machines with high-powered vibration (binding concrete,
0-1” (0-25mm) Very Low
shallow sections)
Low-workabilty mixes that are used for foundations with light reinforcement /
1-2” (25-50mm) Low Pavements consolidated by hand-operated vibrators (mass concrete, beams,
walls, columns)
Medium workability mixes / manually consolidated flat slabs. Normal manually
2-4” (50-100mm) Medium placed reinforced concrete / heavily reinforced sections using mechanical vibration
(strip footings, heavily reinforced sections in slabs)

High High workabilty concrete for sections with congested reinforcement (pumped
4-7” (100-175mm)
concrete, trench fill, slipform work)
