Limits on free fall of concrete - PMDC

Specify if free-fall concrete is not permitted or if the free-fall height is limited. Recent research on free-fall concrete has confirmed that free fall does not cause segregation, at least for fall heights up to 60 ft (18 m) and pier diameters as small as 3 ft (1 m) with 10 in. (750 mm) diameter cages.

Placement and Design of Concrete in Drilled Shaft

Nov 12, 2018 · Studies have demonstrated that free fall placement of concrete does not impact the compressive strength of the concrete. It also does not result in any observable segregation of the mix. In one study, results suggested that free-fallen concrete drove out air, produced denser concrete, and actually produced stronger concrete.

Batching, Mixing, Placing and Compaction of Concrete

Mar 18, 2017 · A pan type mixer is a forced–action mixer, as distinct from drum mixer which relies on the free fall of the concrete inside the drum. The pan mixer consist of a circular pan rotating about its axis with one or two stars paddles rotating about vertical axis of pan. Dual drum mixer: A dual drum is sometimes used in highway construction.

Production and placement of self-compacting concrete

Jan 01, 2020 · As a result, some specifications do not allow the use of free-fall mixers to produce SCC. Mixers that can provide a higher shear rate to concrete by well-arranged blades and higher power can produce concrete with a very low yield stress, which is more suitable to achieve self-compacting properties (Hemalatha et al., 2015).

Max free fall for ready-mix concrete - ACI (concrete) Code

Usually they limit the free-fall distance to 3 to 5 ft (0.9 to 1.5 m), but occasionally the limit is as little as 2 ft (0.6 m). Neither ACI 301- 99, "Specifications for Structural Concrete," nor ACI 318-02, "Building Code Requirements for Structural Concrete," limit the maximum distance concrete can free fall.
