#67 Stone
Vulcan Materials Company · No. 67
A coarse aggregate in the No. 67 size - nominally 3/4 inch to No. 4, a half-step finer at the top than No. 57 and the size most often called for in structural concrete where the member is congested or the cover is tight. The producer lists it among its coarse stone products; as with every size number here, the gradation is defined by the standard table and not by the producer.
