Explanation:
Concrete placing operations are often planned to allow for the free fall of concrete. This planning must also consider any segregation that might occur when the concrete free falls into place.
In typical residential construction, concrete is commonly placed in a wall to a maximum of 10 to 12 feet in height during one concrete pour. This is done in multiple lifts of around 4 feet or less. In commercial construction walls may be higher -14 to 18 feet.
