Zero-Slump Concrete: A Straight-Up Tool in a Tough

Consider this: A zero-slump concrete mix can be used to manufacture a wide variety of precast concrete products just as a conventional wet-cast or SCC (self-consolidating concrete) mix can. However, if your market demands higher

Batch Systems for Dry Cast, Wet Cast, Ready Mix — Ashlar ...

Wet-cast concrete is preferred for larger, more complex forms that need greater flowability throughout the form or around reinforcements. Dry-cast concrete, on the other hand, has a low water-to-cement ratio. It is very rigid, dry, and shows no measurable slump, zero-slump or negative-slump, after the removal of a slump cone.

(PDF) CONCRETE MIX, SLUMP AND CONCRETE

With a workable concrete mix, slump test and making concrete cubes was also done. Slump test When making the slump test, the base of the slump cone was put on a flat surface. The cone was then filled with wet concrete in three layers. Each layer was tempered 25 times with a standard 16mm (diameter steel rod, rounded at the end).

2021-1-10  Zero slump – This result indicates the mix is to dry with a very low water-cement ratio with low workability, but dry mixes are used in road construction. Collapsed slump – The concrete mix completely collapses and this result indicates a very high water-cement ratio (too wet or high workability mix) and the slump test is not appropriate.

Producing no-slump concrete

no-slump concrete tends to build up on equipment faster than con-ventional concrete, and more fre-quent cleaning may be required. Testing By definition, the aspect of no-slump concrete which separates it from most other concrete work is the measurement of consistency. ACI 211.3 is a procedure for pro-portioning no-slump concrete and

Guide To Concrete Workability Concrete Slump

Concrete workability. One of the basic attributes of any concrete is its workability or "consistence", that is, how easy it is to push one way, pull the other, and float to a smooth level surface. Workability is largely determined by how fluid the concrete is. This is referred to as "Slump". Essentially, the more fluid the concrete, the higher ...
