\5.4 Concrete Form Release Agent

==

Description:==

Release agents are applied to the form contact surfaces to prevent bond and facilitate stripping. They may be applied to the form before each use, at which time care must be exercised to prevent coating adjacent construction joint surfaces or reinforcing steel. A good release agent should provide a clean and easy release without damage to either the concrete face or the form, while contributing to the production of blemish free surface. It should have no adverse effect upon either the form or the concrete surface.

When applied improperly, form oil may prevent bond between the concrete and reinforcing bars or weaken joints by preventing bond of old to new concrete.

Data to be collected and Analyzed:

1. Review concrete placement specifications.

2. Review Quality Control (QC) specifications.

3. Review QC reports.

Verified Supporting Evidence: None Verified Refuting Evidence:

a. Project specifications (FM 5.4 Exhibit 1 - Specification SP-5618) require that forms are thoroughly cleaned after each use, and surfaces in contact with concrete be coated with form oil which has been approved by the OWNER.

b. Project QC specifications (FM 5.4 Exhibit 2) included requirements for verifying form oiling and cleanliness of all surfaces prior to concrete placement.

c. QC reports (representative example in FM 5.4 Exhibit 3) show that inspectors followed the established QC specifications and monitored proper form coating.

d. Exhaustive review of Non-Conformance Reports (NCRs) found no evidence of improper application of form oil during the construction of the containment building.

==

Conclusion:==

Form release agents were applied properly and were not a contributing factor to the delamination.

1. Testing laboratory inspectors shall perform the following Inspections and shall docunent this inspection on each placement. (Sample inspection form attached.)

a. Forwmork for cleanliness, tight joints, form oiling and exposed edges chamfered.

I b. Reinforcement for cleanliness,I adequate securing and clearances to forms and subgrades.

c. Construction joint surfaces except as noted otherwise hereinafter shall be prepared for the placement of concrete there on by cleaning thoroughly with wire brushes, water under pressure, or by other meansi to remove all coati ,

stains, debris, or other foreign material.

d. Horizontal and vertical construction joints in the reactor building cylinderical shell below 250'0 levie shall be prepared for receiving next pour by either sandblasting, air water jet, bush hammering, or other means to-remove all coatings, stains, debris or onter I m

foreign mterial. The horizontal joints shall be I dampened, then thoroughly covered wthI cement san mortar, of similar proportions in concrete, of approximately 1/2 inch thick and 'oncrete placed before initial set of mortar. Vertical joints shall be dampened before concreting.

e. Construction joint surface In the Ring Girder and Dome at and above 250'0 of the Reactor Bldg. are to be prepared by sandblasting to produce a clean rough surface and the applying an evenly distributed film of Colma Fix 8% adhesive.

f. Conveyance equipment in accordance with ACI 301 Chapter 8 and ASTh C94. All transporting to point of deposit to be without segregation of concrete.

g. Concrete deposited in horizontal layer not exceeding 18" avoiding inclined joints with maximm free fall of 3 feet.

Each layer vibrated together.

h. Placing of concrete shall not cause movement or damage to embedded items.

I. Concrete vibrated adequately and concrete of proper workability to avoid seams or planes of weakness.
