i 1 stnogutY - Compatibility testing was initiated at the request of Brown I and Root engineers relative to the South Texas Project. E1cometer adhesion and DBA tests were conducted to demonstrate the compatibility of Concresive 1411 to Imperial's NUTEC 11S/REACTIC 1201 system. The results of these tests indicate that the Concresive 1411 is compatible with the Ispecial products.

L Ilfrn0 DUCTION - Concresive 1411 is a 100% epoxy masonry and concrete mortar which is designated for use in repairing concrete damage at the South Texas Project. Brown and Root engineers requested that Imperial conduct tests to dem nstrate that the proposed NUTEC llS/REACTIC 1201 g coating system and Concresive 1411 are compatible.

1 High strength aluminum dollies were applied to the mated spec 4==n= by means of an epoxy resin-type adhesive.

The dollies were placed 1-13-78 at 11:00 a.m. and removed i

with an E1cometer adhesion testar 1-16-78 at 9:00 a.m.

2. two of the six concreta specimens were then submitted to Coastal Science Associates for DBA testing in accordance with the test parameters established for the South Texas Project. The concrete coupons were subjected to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> i of LOCA simulated conditions with a ==w4== temperature of j 307 F. and a =mwi=ina pressure of approximately 57 psig.

The coating damage inflicted by the Elcometer testing was J

not repaired prior to IBA testing.

observation was confirmed by removing the coating in the

" defective" areas. The failure was found to occur betwoen the Concresive 1411 and the concrete surface.

CONCLUSIOBIS - The results of the Eloometer adhesion and DBA testing demonstrates the campatibility of Concresive 1411 with the Imperial coating system. In all tests, the bond between the Concresive 1411 and the NOTEC #11S was excellent.

Some failures, however, did occur between the concrete surface and the Concresive 1411. Speciman # 3707 exhibited scoe loss of adhesion at the

, substrate in the adhesion test and specimen #3710 exhibited signs of

} delanination in the ImA test. This potentimi problem can be avoided by good surface preparation practices. The concrete speci==n= used had aged for 20 months. Apparently some con *==ination was present which was not readily removed by 100 psi compressed air. Use of Concresive 1411 should be restricted to damaged concrete, voids, and tie holes where a " physical

, bond" will be achieved and improve the performance of the overall system.

Excess Concresive 1411 should be removed to avoid any potential adhesion problems.
