Description:

Early age cracking can occur when concrete is exposed to stresses exceeding its capacity before it matured and gained strength.

These cracks are usually the result of early, excessive drying shrinkage.

They may also occur when forms and supports are removed too early and excessive loads are imposed on the structure before the concrete reached its design strength.These cracks can extend the full depth of the element and lead to early failure from strength loss and/or durability related distress.Data to be collected and Analyzed: 1. Review reports from original construction regarding curing and form removal procedures. (FM 2.4 Exhibit 1)2. Inspect for visible cracks in the SGR hole cut zone.3. Review strength development of original concrete. (FM 2.4 Exhibit 2)Verified Refuting Evidence:

Verified Supporting Evidence: a) There are no reports or NCRs addressing early age cracking of the containment structure.

Not applicable b) Records of construction methodology, and especially curing and form stripping records, indicate that the concrete was not exposed or allowed to dry for at least seven (7) days after pouring as recommended by concrete industry standards. (FM 2.4 Exhibit 1)c) Form stripping records show that the concrete was supported for at least seven days, at which time it reached 70-80% of measured 28 day strength. (FM 2.4 Exhibit 2)Conclusion:

Adequate steps to prevent early age cracking were taken.Reviewed by" Dr. Avi Mor, 352-795-6486, ext 1030- PII CR3 Team Office evidence.DJIOR~May identify additional perspective on this issue as RCA related efforts proceeds 3/19/2010 Dv iil ettea to third poa without permission 1
