E. Cure specimens under laboratory conditions except that when in the opinion of the Engineer,
there is a possibility of the surrounding air temperature falling below 40 degrees F., additional
specimens may be required and cured under job conditions.
F. If the average strength of the laboratory control cylinders for any portion of the structure falls
below the compressive strengths called for on the Drawings, the Engineer has the right to order a
change in the proportions or the water content for the remaining portion of the structure. If the
average strength of the job-cured cylinders falls below the required strength the Engineer has the
right to require conditions of temperature and moisture necessary to secure the required strength
and may require tests in accordance with ASTM C42, or order load tests to be made on the
portions of the structure so affected. Remove or replace failing concrete if directed by the
Engineer.
