Notes:
The S.W.COLE Construction Services Technician arrived onsite at approximately 6:45AM.
Concrete placement activities were observed during the time the S.W.COLE rep was onsite
performing sampling and testing services.
Concrete Delivery No. 1 arrived onsite consisting of approximately 11 cubic yards of 4,500‑psi
concrete with 1‑1/2‑inch aggregate. Sika 75 admixture was added prior to placement. The
concrete was placed via pump truck.
One set of field tests were performed on sampled concrete with the following results:
Truck 73 – Load 1
Slump: 8 inches
Air Content: 4 percent
Concrete Temperature: 71°F
One set of compression test cylinders was cast for laboratory testing at 7, 14, and 28 days (two
cylinders per test age), along with one hold cylinder. Laboratory compressive strength test
results will be reported separately upon completion of testing.
Second Placement:
Concrete Delivery No. 1 arrived onsite consisting of approximately 11 cubic yards of 4,500‑psi
concrete with 3/4‑inch aggregate. Sika 75 admixture was added prior to placement. The
concrete was placed via pump truck.
One set of field tests were performed on sampled concrete with the following results:
Truck 64 – Load 1
Slump: 8.5 inches
Air Content: 3.5 percent
Concrete Temperature: 72°F
One set of compression test cylinders was cast for laboratory testing at 7, 14, and 28 days (three
cylinders per test age), along with one hold cylinder. Laboratory compressive strength test
results will be reported separately upon completion of testing.
Test results and observations were verbally reported to Rayssa (CDM Smith) while onsite.
The S.W.COLE rep departed the site at approximately 12:15 PM after completing the requested
