1 1. Slump Flow. <br /> 2 <br /> 3 a. The mix design shall specify the target slump flow in inches, in <br /> 4 accordance with WSDOT FOP for ASTM C 1611. The slump flow range is <br /> 5 defined as the target slump flow plus or minus 2-inches. <br /> 6 <br /> 7 b. The visual stability index (VSI) shall be less than or equal to 1, in <br /> 8 accordance with ASTM C 1611, Appendix X1, using Filling Procedure B. <br /> 9 <br /> 111 <br /> 10 c. The T50 flow rate results shall be less than 6-seconds in accordance with <br /> 11 ASTM C 1611, Appendix X1, using Filling Procedure B. <br /> 12 <br /> 13 2. Column Segregation. <br /> 14 <br /> 15 a. The maximum static segregation shall be 10-percent in accordance with <br /> 16 ASTM C 1610. <br /> 17 <br /> 18 b. The Maximum Hardened Visual Stability Index (HVSI) shall be 1 in <br /> 19 accordance with AASHTO PP 58. <br /> 20 <br /> 21 3. J ring test results for passing ability shall be less than or equal to 1.5-inches in <br /> 22 accordance with the WSDOT FOP for ASTM C 1621. <br /> 23 <br /> 24 4. Rapid assessment of static segregation resistance of self-consolidating <br /> 25 concrete using penetration test in accordance with ASTM C 1712 shall be less <br /> 26 than or equal to 15 mm. <br /> 27 <br /> 28 5. Air content shall be tested in accordance with WSDOT Test Method T 818, <br /> 29 and shall conform to Section 6-02.3(2)A. <br /> 30 <br /> 31 6. Concrete unit weight results in pounds per cubic foot shall be recorded in <br /> 32 accordance with AASHTO T 121, except that the concrete shall not be <br /> 33 consolidated in the test mold. <br /> 34 <br /> 35 7. The temperature of all concrete laboratory test samples shall be tested in <br /> 36 accordance with AASHTO T 309 and shall conform to the placement limits <br /> 37 specified in Section 6-02.3(4)D. <br /> 38 <br /> 39 8. The modulus of elasticity in pounds per square inch at 28 days shall be <br /> 40 recorded in accordance with ASTM C 469. <br /> 41 <br /> 42 In lieu of a Contractor-Provided mix design for SCC for Section 6-02.3(27)A Structure <br /> 43 elements 3, 7 and 8, a representative full-size example Structure element shall be cast <br /> 44 for inspection by the Contracting Agency in accordance with Section 6-02.3(27)B as a <br /> 45 component of the precast fabricating facility's annual plant approval process. <br /> 46 <br /> 47 6-02.3(4)C Consistency <br /> 48 This section is supplemented with the following new paragraph: <br /> 49 <br /> 50 For self-consolidating concrete (SCC), the slump requirements specified above do not <br /> 51 apply, and are instead replaced by the target slump flow and slump flow range specified <br /> 52 as part of the SCC mix design. <br /> I <br /> AMENDMENTS TO THE 2014 STANDARD SPECIFICATIONS BOOK <br /> Revised: 8/3/15 <br />
