At the discretion of the Company Representative, the Contractor may be directed to take additional test samples at no additional cost to the Company.

Test samples shall remain at the site exposed to the same conditions as the placed concrete for the first twenty-four (24) hours. Following the twenty-four (24) hours field cure period, the cylinders shall be immediately transported to a laboratory for controlled curing and testing. During periods of cold weather, the cylinders shall be transported in a temperature-controlled environmental (60- 80°F) or shall otherwise be insulated to protect against freezing.
