Concrete Placement Information

Location(S): N/A

Testing: 4 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: 4 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
