When constructing a sliding formwork, concrete is poured into the formwork which is constantly moving. When the concrete is poured, the formwork rises vertically at a rate that allows the concrete to harden before it detaches from the formwork at the bottom.
The concrete to be used must be workable enough to be formed and set by vibration but hardens quickly enough to be deformed by force. Concrete must always be monitored for setting speed so that the mold does not rise too quickly. You can also get information about slip form concrete silo through https:/borton.net/.

Advantages of slipforms konstruksi construction
High production speeds can be achieved by pushing, but once a long casting job has started, there is little flexibility for changes and therefore very careful planning is required.
Only minimal scaffolding and temporary work are required, meaning that the construction site is less overloaded and therefore safer.
Exposed concrete can be covered at the bottom of the rising formwork.
The main cost of constructing a concrete structure is the formwork required to hold the concrete in place, while it can be safely dismantled and withstand itself and other imposed loads.
The formwork must be constantly removed in newer places and then rebuilt.
Shear formwork is one of the best techniques for quick construction in unusual structures such as cooling towers, chimneys, silos, and bridge construction.
Sliding formwork technology with a structure of more than 16 m high and its assembly technology is very fast, time-saving, and economical.
