Foundation and Concrete Construction

Question 1
To prevent the segregation of aggregate, what is the maximum vertical distance concrete is permitted to drop freely?
Active Guidance

Caltrans and ACI standards limit the free fall of concrete to no more than 5 ft to prevent heavy aggregates from separating from the mortar. Falls exceeding this height require the use of a tremie or chute.
