what is the best wat to transfer concrete from top to bottom(180m high)?

Answer 1

You don't give enough information to answer this question. So some of these will apply and others won't
Long Hose (concrete type), Tubing (size dependent on size of concrete fill needed). Simple Drop (pour it in and let it fall). Ramp with sides. More info better answer (size of hole to fill and fill height diameter - is concrete on the top or on the ground and pumped up to the top and then back down. This type of question is like the string question (How long is a piece of string?)

Answer 2

If the concrete is very workable it can be pumped up easily to the heights you mention, a typical skyscrpaer 180 m in the air

especially because at the top of a building the concrte is usually less strong and therefore more workable

If the concrete is not workable enough to flow through a pipe, a crane would ahve to lift a large batch of the concrete to the top of the building

Workability is a measure of a concrete's viscosity

Answer 3

Lets assume your wanting to place concrete into something from a height of 180meters. Well, you can't just drop it down a chute, because the amount of energy you'd impart to the aggregate would cause it to segregate at the bottom of the pour and wreck the strength characteristics. You would probably need to use a concrete pump, to place it that far down. If you had the room to slope a trough enough to use it, I would assume you could then place it from a lower elevation.

Answer 4

concrete companies have pumping systems to do this. Also use crane and bottom dump bucket.
