Slip-Form Productivity Analysis for Concrete Silos

Starting from the beginning of the 20-century, slip-forming is widely used in formwork due to fast concrete work. Slip-forming is one of the potential concrete formwork methods that improves speed and productivity of repetitive vertical concrete work. Typical projects that employ this technique are: silos, core of high-rise buildings, telecommunication towers, cooling towers, heavy concrete offshore platforms, etc. Current research aims at assessing slip-form productivity using simulation as well as determining the best slip-form rate and resource combination. A simulation model for slip-forming technique is developed. Data are collected from a case study in slip-forming of concrete silo. The potential control units in the system are described while applying the developed model to the case study. Results show the usefulness of applying the developed simulation model to slip-forming technique with robust results of 99% validation.
