Drilled shaft refers to a deep foundation system where a single large diameter pier is used to replace a whole group of piles. Florida Department of Transportation (FDOT) specification 346-3.2 requires that the concrete used for the construction of drilled shaft should have a slump between 7 and 9 inch (180 and 230 mm) when placed and should maintain a slump of 4 inch (25 mm) or more throughout the concrete placement time. Furthermore, it requires that the mix for the slump loss test should be prepared at a temperature consistent with the highest ambient or initial concrete temperature (whichever is greater) expected during actual concrete placement.
