(TEC Services) is an AASHTO R18 and International Accreditation Services (IAS) (TL-458) accredited laboratory in compliance with ANS/ISO/IEC 17025:2005 and is an Army Corps of Engineering approved laboratory. TEC Services is pleased to present this report of our compliance verification testing of SLICK-PAK, an ASTM C 494-10 Type S (Specific Performance) admixture. All sample preparation and testing was performed in accordance with applicable sections of AASHTO M194-06, ASTM C 494 and documents referenced therein. Material and procedures outlined in AASHTO M194 were used. Based on our results, SLICK-PAK complies with the requirements in AASHTO M194 and Table 1 of ASTM C 494. These test results pertain only to the sample tested. The compliance verification was performed in TEC Service s laboratory in Lawrenceville, Georgia. Concrete batching was carried out on three different days in September, 2011. One control mixture and one test mixture containing SLICK-PAK, both meeting the requirements of AASHTO M194 and ASTM C 494 for fresh concrete properties, were produced each day. A 1- gallon sample of SLICK-PAK was manufactured and supplied to TEC Service by FRITZ-PAK Corporation. The air-entraining agent used in this testing was a commercially available vinsol resin admixture, meeting the requirements of AASHTO M154-06. Testing of the concrete s plastic properties, time of setting, compressive strengths, flexural strengths, length change, and freeze thaw resistance were performed by TEC Services. Determination of the admixture s specific gravity, solids content, and ph were performed by TEC Services. Determination of the admixture s chloride content was performed by Wyoming Analytical Laboratories and the IR analysis was performed by Applied Technical Services. Mixture proportions and results of our testing are given in Tables 1 to 3. Information and test data on fine and coarse aggregates are listed in Tables 4 to 6. Table 7 contains information supplied by the producers of the SLICK-PAK. Product information and test data on the Type I cement is included in Table 8. Test results for each of the six batches prepared for this report are included in Tables 9 through 12.
