What slump is allowed for structural concrete on South Carolina highway projects?
"Batches of Class 2500 concrete with slumps greater than 4 in. after the allowable addition of cement will not be accepted for Department use." [2] "Before discharge into forms, the Department’s representative will perform entrained air content (as determined by ASTM C231 or ASTM C173) and slump (as determined by ASTM C143) tests on the first concrete truck to arrive at the point of delivery for every pour to ensure specification compliance." [4] "If either the entrained air content or slump testing yields a test result that is outside of the allowable range, the Department’s representative will perform one retest on a different sample of the load in question." [4]
