Concrete Placement Information

Location(S):
Testing: One set Set of concrete specimens (6 Cylinders per set) were cast during the cast-in-place concrete pour at the above referenced location, in accordance with ASTM C31. The cylinders will remain on site for the initial 24-48 hrs curing.
Compliance:

Field placement of concrete appeared to be in accordance with the project specifications (i.e., slump, temperature, etc) (refer to remarks below)

Deviations and/or noncompliances were noted during the field placement (refer to remarks below)
Cylinders
Pick Up: One set Sets of concrete cylinders/ 6 cylinders per set were picked up & transported to AS Engineering and Consulting LLC (ASEC) for curing and testing in accordance with ASTM C39, C670/1231
Field Curing: Cylinders were stored for the initial 24 hours
Near the poured structure
In an insulated curing box
Other
Remarks: Once arrived at the project for the concrete placement, I followed up on another observation of project to make sure everything was still acceptable. When the testing was completed, the Air was not in compliance with specifications. I discussed with the contractor about the air not falling into specification. On the second load another Air check was completed, and the air came up to 1.3%. The contractor was informed as well of the air not being in compliance with specifications. slump: 4.75 air: 2.5% temp: 63 unit weight: 144.4 pcf air re-check: 1.3 %
