Concrete Placement Information
Location(S):
N/A
Testing:
One set Set of concrete specimens (6 per set) were cast during the cast-in-place concrete pour at the above referenced location, in accordance with ASTM C31. The specimen 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)
Specimen
Pick Up: One set Sets of concrete specimens/ 6 specimen per set were picked up & transported to AS Engineering and Consulting LLC (ASEC) for curing and testing in accordance with ASTM C39, C670/1231
Pick Up: One set Sets of concrete specimens/ 6 specimen 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:
Specimen 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 %
