The grade of wireshall conform to AASHTO M-32. Welded Steel Wire Fabric shall conform to ASTMA-185 (AASHTO M-55).C.CementThe cement shall be of a recognized standard brand of Portland Cementconforming to the specification requirements listed below and of a type listed below:SpecificationType Portland CementASTM C-150Type I, III*AASHTO M-85Type I, III**Type III cement may be used upon written authorization of the Engineersubject to the following modification:Minimum design strength shall be achieved in seven (7) days in lieu of thetwenty-eight (28) days required for Type I cement.For architectural concrete only one brand of cement shall be used unless otherwiseapproved by the Engineer. When no type cement is specified, the requirements ofType I shall govern.Cement reclaimed from cleaning bags or leaking containers shall not be used.The Engineer may require an additional one-half sack of Portland concrete over thedesign specification.D.WaterWater used for the mixing of concrete shall be clean and free of oil or acid, andshall not contain salt, alkali, or organic matter.E.AggregatesAggregates for Portland Cement Concrete shall be well graded, clean, hard gravel,and coarse sand, non-frost susceptible material, and free of deleterious (organic)Page 3Standard Construction SpecificationsDivision 30 – Portland Cement ConcreteRevised 11/08
