USA - Concrete silos make a new landmark in Alabama
Montgomery, Alabama's state capital, has experienced strong growth with, in addition to expansion in the car manufacturing industry, expansion of Koch Foods.
Founded in 1985 as a small chicken deboning and cutting operation with just 13 employees, Koch Food has becime one of the top poultry processors in the United States. In 2016 Koch Foods undertook major upgrades to one of its feed mills.
Kirkpatrick Concrete Company (KCI) was chosen to supply concrete for construction of two 73-m-tall, 21-m-diameter silos separated by a 10-m-diameter silo. The concrete was supplied from the batching plants of KCI's southern Alabama operation. The silos were built on grout-filled hollow-flight auger piles held together by a monolithic pile cap slab.
KCI had to keep up constant and regular deliveries by at least 30 trucks to meet the pouring rate of 230 m3/h througjout the night. The silos were then slipformed in one continuous operation over six days.
