1 2018 Standard Specifications M 41-10 Page 9-1 Division 9 Materials9-00 Definitions and Fracture Fractured aggregate is defined as an angular, rough, or broken surface of an aggregate particle created by crushing, or by other means. A face is considered a fractured face whenever one-half or more of the projected area, when viewed normal to that face, is fractured with sharp and well-defined edges: this excludes small Wood WasteWood waste is defined as all material which, after drying to constant weight, has a specific gravity of less than Test for Mass of GalvanizingAt the option of the Engineer, the weight of zinc in ounce per square foot required by the various galvanizing Specifications may be determined by an approved magnetic thickness gage suitably checked and demonstrated for accuracy, in lieu of the other methods Sieves for Testing PurposesTest sieves shall be made of either.

2 (1) woven wire cloth conforming to AASHTO Designation M 92 or ASTM Designation E 11, or (2) square-hole, perforated plates conforming to ASTM Designation E Dust RatioThe dust ratio is defined as the percent of material passing the No. 200 sieve divided by the percent of material passing the No. 40 Sand/Silt RatioThe sand/silt ratio is defined as the percent of material passing the No. 10 sieve divided by the percent of material passing the No. 200 Galvanized Hardware, AASHTO M232An acceptable alternate to hot-dip galvanizing in accordance with AASHTO M 232 will be zinc coatings mechanically deposited in accordance with AASHTO M 298, providing the minimum thickness of zinc coating is not less than that specified in AASHTO M232, and the process will not produce hydrogen embrittlement in the base metal.

3 Sampling and testing will be made by the Engineer in accordance with commonly recognized national standards and methods used in the laboratory of the Department of Sand EquivalentThe sand equivalent will be the average of duplicate determinations from a single sample. The sand equivalent sample will be prepared in accordance with the FOP for AASHTO T acceptance, there must be a clear line of demarcation. If no clear line of demarcation has formed at the end of a 30-minute sedimentation period, the material will be considered as failing to meet the minimum specified sand Field Test ProceduresField test procedures may be either a Standard Operating Procedure (SOP) or a Field Operating Procedure (FOP) for an AASHTO, ASTM, or WAQTC test procedure.

4 A Field Operating Procedure is a technically equivalent abridged version of an AASHTO, ASTM, or WAQTC test procedure for use in field conditions. References to manuals containing all of these tests and procedures can be found in Section (1).Page 9-2 2018 Standard Specifications M 41-109-01 Cement9-01 Types of CementCement shall be classified as portland cement, blended hydraulic cement, or rapidhardening hydraulic (1) Portland CementPortland cement shall meet the requirements of AASHTO M85 or ASTM C150 Types I, II,or III portland cement, except that the cement shall not contain more than percent alkalies by weight calculated as Na20 plus K20 and the content of Tricalcium aluminate (C3A) shall not exceed 8 percent by time of setting shall be determined by the Vicat Test method in accordance with AASHTO T 131 or ASTM (1)

5 A Low Alkali CementWhen low alkali portland cement is required, the percentage of alkalies in the cement shallnot exceed percent by weight calculated as Na20 plus K20. This limitation shall apply to all types of portland (1)B Blended Hydraulic CementBlended hydraulic cement shall be either Type IP(X)(MS), Type IS(X)(MS), TypeIT(PX)(LY), Type IT(SX)(LY), or Type IL(X) cement conforming to AASHTO M240 or ASTM C595, except that the portland cement used to produce blended hydraulic cement shall not contain more than percent alkalies by weight calculated as Na20 plus K20 and shall meet the following additional IP(X)(MS) Portland-Pozzolan Cement where (X) equals the targeted percentageof fly ash, the fly ash is limited to a maximum of 35 percent by weight of thecementitious material .

6 (MS) indicates moderate sulfate IS(X)(MS) Portland Blast- Furnace Slag Cement, where: (X) equals thetargeted percentage of ground granulated blast-furnace slag, the ground granulatedblast furnace slag is limited to a maximum of 50 percent by weight of the cementitiousmaterial; (MS) indicates moderate sulfate IT(PX)(LY), where (PX) equals the targeted percentage of pozzolan, and (LY)equals the targeted percentage of limestone. The pozzolan (PX) shall be Class F flyash and shall be a maximum of 35 percent. (LY) shall be a minimum of 5 percentand a maximum of 15 percent. Separate testing of each source of fly ash each at eachproposed replacement level shall be conducted in accordance with ASTM at 180 days shall be percent or IT(SX)(LY), where (SX) equals the targeted percentage of slag cement, and (LY)equals the targeted percentage of limestone.

7 (SX) shall be a maximum of 50 percent.(LY) shall be a minimum of 5 percent and a maximum of 15 percent. Separate testingof each source of slag at each proposed replacement level shall be conducted inaccordance with ASTM C1012. Expansion at 180 days shall be percent or IL(X), where (X) equals the targeted percentage of limestone, and shall be aminimum of 5 percent and a maximum of 15 percent. Testing shall be conducted inaccordance with ASTM C1012. Expansion at 180 days shall be percent or source and weight of the fly ash or ground granulated blast furnace slag shall be certified on the cement mill test report or cement certificate of analysis and shall be reported as a percent by weight of the total cementitious material .

8 The fly ash or ground granulated blast furnace slag constituent content in the finished cement will not vary more than plus or minus 5 percent by weight of the finished cement from the certified ash shall meet the requirements of Section of these Standard Standard Specifications M 41-10 Page 9-3 Cement 9-01 Ground granulated blast furnace slag shall meet the requirements of Section of these Standard shall meet the requirements of AASHTO M240 or ASTM (2) Rapid Hardening Hydraulic CementRapid hardening hydraulic cement shall meet the requirements of ASTM C Tests and AcceptanceCement may be accepted by the Engineer based on the cement mill test report number or cement certificate of analysis number indicating full conformance to the Specifications.
