- 5.1.7 Phase I Test Results Summary -The status of each patch material after Phase I testing is shown in Table 6 on thefollowing page. Sample 2, containing the only expansive cement tested (Type K cement),was approved for Phase II testing even though its slow rate of compressive strength gainmight make it impractical for use in some DBR projects. Sample 3, containing theKomponent expansive additive, also advanced to Phase II testing. Based on the change inheight test results for the patch materials containing the Denka expansive additives(Samples 4 through 7), it was determined that the higher dosage rate (50.56 lb/yd 3 or 30kg/m 3 ) was more effective at reducing shrinkage than the lower dosage rate (42.14 lb/yd 3or 25 kg/m 3 ) and the CSA #20 product performed better than the CSA 100R product.From these findings and the desire to select just one Denka product, only Sample 4(containing Denka CSA #20, 50.56 lb/yd 3 or 30 kg/m 3 ) advanced to Phase II of thetesting process; Samples 5,6, and 7 were eliminated. Based on air entraining problemsduring the mixing process, two of the samples containing shrinkage reducing admixtures,Sample 8 (containing Peramin SRA330) and Sample 9 (containing Eclipse Plus), wereeliminated from the study without being tested. Sample 10, containing the other SRA(Tetraguard AS20), was approved for Phase II testing. Sample 11 (containing Solite) andSample 12 (containing Hydrocure), the two lightweight fine aggregate mixes designed toprovide internal curing, were eliminated from Phase II testing due to poor test resultsfrom the change in height test. 8In summary, the following samples advanced to Phase II of the testing process:• Sample 1: Mn/DOT 3U18 (Control),• Sample 2: Mn/DOT 3U18 w/ Type K cement,• Sample 3: Mn/DOT 3U18 w/ Komponent,• Sample 4: Mn/DOT 3U18 w/ Denka CSA #20 (50.56 lb/yd 3 or 30 kg/m 3 ), and• Sample 10: Mn/DOT 3U18 w/ Tetraguard AS20.8 Although the samples containing lightweight fine aggregate (Sample 11 and Sample 12) did not progressto Phase II testing, upon the completion of this research study, additional testing was conducted on a patchmaterial containing a higher percentage of Hydrocure LWFA. The results of the testing are included inAppendix C and show that internal curing can successfully reduce shrinkage.22
