Maximum Aggregate SizeLarger aggregates can make pumping the concrete more difficult and can affect some finishes. Smaller Maximum Aggregate Size in Concrete. In some cases smaller aggregates have been found to be more resistant to freeze thaw cycles. This is particularly evident in concrete pavements where D cracking can be a problem in freezethaw affected areas.
