Notes:
S.W. Cole Engineering Construction Services Technician Robert Reuter arrived onsite at 6:20 am for "Concrete Field Testing" for
the placement location referenced above.
Upon arrival, met with Eric Salo from CDM Smith who provided information about today's job duties.
RLR would be testing concrete for the SRP slabs 11 and 15. Also the process building basement slab north and south.
Concrete was delivered by "Cape Cod ready mix" and was a 1-1/2", 4500psi, Concrete Mix with HRWR and (330) cubic yards of
concrete were placed.
The mix specifications were as follows:
Slump: 7.00in - 10.00in
Air Content: 3% - 6% (Air entrained mix).
Samples were collected from loads 2,12,22,32 and the standardized testing was performed with the following results:
First Placed Load (Truck#69)
Slump: 7-1/2” in.
Air Content: 4.0%
Concrete Temperature of 74F°
Second Placed Load (Truck#80)
Slump: 10” in.
Air Content: 5.0%
Concrete Temperature of 60F°
Third Placed Load (Truck#62)
Slump: 8-3/4” in.
Air Content: 4.0%
Concrete Temperature of 66F°
