The specifications may reference a specific cement type for a construction application. When a cement type is specified, the cement type referenced is applicable to Section 750 A; however, the Contractor may use any of the following cements: A.Portland Cement : Portland cement will conform to AASHTO M 85 for the type specified. All cements will not have more than 0.60% of Alkalis (Na2O + 0.658K2O). B.Portland Limestone Cement (PLC): Portland limestone cement will conform to AASHTO M 240 Type IL. When Type II cement is specified, the cement will meet MS requirements of AASHTO M 240. When Type V cement is specified, the cement will meet HS requirements of AASHTO M 240. The Contractor will submit ASTM C1012 test results from within the last 12 months to the Engineer prior to using Portland limestone cement. C.Portland-Pozzolan Cement: Portland-pozzolan cement will conform to AASHTO M 240 Type IP. When Type II cement is specified, the cement will meet MS requirements of AASHTO M 240. When Type V cement is specified, the cement will meet HS requirements of AASHTO M 240. The Contractor will submit ASTM C1012 test results from within the last 12 months to the Engineer prior to using Portland-pozzolan cement. Fly ash used in the cement manufacturing will meet the requirements of Section 753. The fly ash content will meet the fly ash percent specified. Fly ash may not be substituted for a portion of the Portland-pozzolan cement during concrete production. If a different pozzolan is used in the cement manufacturing, the Portland-pozzolan cement will meet equivalent performance of historical fly ash percent specified mixes, as determined and reviewed by the Department’s Concrete Engineer. D.Ternary Blended Cement: Ternary blended cement will conform to AASHTO M 240 Type IT. When Type II cement is specified, the cement will meet MS requirements of AASHTO M 240. When Type V cement is specified, the cement will meet HS requirements of AASHTO M 240. The Contractor will submit ASTM C1012 test results from within the last 12 months to the Engineer prior to using ternary blended cement. The ternary blended cement will meet the equivalent performance of historical fly ash percent specified mixes, as determined and reviewed by the Department’s Concrete Engineer. Fly ash may not be substituted for a portion of the ternary blended cement during concrete production.
