ATTACHMENT RII:JRH 50-389/79-08 INFRACTION:
Curing of Concrete Test Cylinders - Failure to Follow Procedures Procedures gI 10.71 and Specification FLO-2998-473 specify that concrete test cylinders will be cured in accordance with ASTM C-31 and ASTM C-511.
The inspector found the following examples which were contrary to these require-ments:
1)
Contrary to the allowable 60 to 80 degree Fahrenheit range in ASTM C-31, on May 31, 1979, temperatures adjacent to field cured test cylinder set numbers 6147 and 6149 were 90 degrees and 86 degrees Fahrenheit respectively.
2)
Contrary to ASTM C-511, in the laboratory curing room free water was not visible on test specimens stored along the right wall.
3)
No documentation was available to support the 95 percent relative humidity requirement of ASTM C-511.
RESPONSE
Based on the information provided to FPL by Nr. J.
R. Harris's exit interview, Construction OC determined the necessary corrective actions and took immediate steps to implement these actions.
Full compliance was confirmed by Mr.
R.
W. Wright during the week of June ll, 1979.
Corrective actions taken to resolve the above noncompliance are as follows:
1)
Concrete test cylinders are now being molded to comply with the requirements of ASTM C-31 and C-172'n order to maintain the initial curing temperature of 60-80 F during hot weather, the concrete specimens are being molded in the concrete laboratory.
2)
New spray heads have been installed in the laboratory curing room spray system to assure all cylinders stored in the curing room are thoroughly wetted.
3)
The recording of humidity in the moist curing room is optional, according to ASTM C-511, only temperature recording is mandatory.
However, for our own information, humidity in the curing room is now being recorded.
