SECTION 801 CEMENT
801.01 REQUIREMENTS. Provide Portland cement or blended hydraulic cement from
approved mills listed in the Department's List of Approved Materials. Mills obtain approval by furnishing the Department samples and certified mill test data developed over the previous 6 months. Approved cement mill laboratories are AASHTO accredited in ASTM C150 test methods. Foreign cements are added to the approved list based upon testing by the sponsoring approved cement mill laboratory along with submittal and approval of verification samples. When supplying cement with a SO 3 content above the value in table I of ASTM C 150, include supportive ASTM C 1038 14-day expansion test data for the supplied SO 3 content on the certification. The Department will require a signed certification from the supplier for each shipment of cement stating that the cement complies with the applicable ASTM standard and all additional requirements of this subsection. Conform to the following requirements for cement:
1.Type I, II, III, IV, and V Portland cement conforms to ASTM C 150. State, on the mill certification, the nature, amount, and identity of any processing addition and its compliance with ASTM C 465.
2.Type E-1(K) conforms to ASTM C 845.
3.Type IP (≤20), Portland-pozzolan cement, conforms to ASTM C595, and the following additional requirements to Type IP ( ≤20).
a.The pozzolan constituent shall be fly ash. Ensure that the loss on ignition of the fly ash does not exceed 3.0 percent.
b.The cement manufacturer shall furnish to the Engineer reports showing the results of tests performed on the fly ash used in the manufacture of the Type IP( ≤20) cement shipped to the project.
c.The cement manufacturer shall have a qua lified technical representative readily available for consultations on the project at any time the Engineer deems necessary, at no expense to the Department.
d.Use only one brand of Type IP( ≤20) cement throughout the project, unless the Engineer approves otherwise.
4.Type IS( ≤30), Portland blast furnace slag cement, conforms to ASTM C 595 and the following requirements:
a.Use Grade 100 or 120 blast furnace slag cement conforming to the requirements of ASTM C 989.
b.The cement manufacturer shall furnish to the Engineer reports showing the results of the tests performed on the blast furnace slag cement used in the manufacturing of the Type IS( ≤30) shipped to the project.
c.The cement manufacturer shall have a qua lified technical representative readily available for consultation on the project at anytime the Engineer deems necessary, at no expense to the Department.
d.Use only one brand of Type IS( ≤30) cement throughout the project, unless the Engineer approves otherwise.
5.Type IL(5-15), Portland-limestone cement, conforms to ASTM C 595 and the following additional requirements:
a.The cement manufacturer shall furnish to the Engineer reports showing the results of test performed on the limestone used in the manufacture of the Type IL cement 801-1 shipped to the project.
b.Use only one brand of Type IL cement th roughout the project, unless the Engineer approves otherwise.
c.The Type IL blended cement shall be an intimate and uniform blend produced by intergrinding of the Portland cement and limestone. Even when tested and approved, do not mix cement from different mills in individual batches or use cement from different mills in alternate batches of concrete. Subject to the above restrictions, the Engineer may allow the use of cements from different mills for any structure or individual elements of a structur e, provided color contrasts resulting from their usage is minimal or is otherwise unobjectionable and identification of the location of concrete containing the different cements is satisfactorily maintained. Store cement to prevent damage from the elements. Provide weatherproof storage facilities with sufficient storage capacity that cements from different mills or of different types will not become intermixed. Provide an acceptable means for obtaining samples, from either the cement silo, weigh hopper, or truck. The Engineer will reject cement that for any reason has become damaged through contamination, partial set, or which contains lumps of caked cement. The Engineer may reject the entire contents of a container when it contains damaged cement.
801.02 NON-SPECIFICATION CEMENT. The Department accepts cement on the
basis of manufacturer’s certification attesting to type and conformance to the applicable ASTM specification. The Engineer will take check samples. When the check samples do not conform to these specifications, the Department will make deductions as shown in the following table. When a sample fails more than one test, the Department will make the total deduction as the sum of deductions up to a maximum of 100 percent. 801-2 TEST MAXIMUM DEVIATION FROM REQUIREMENT (PERCENT) DEDUCTION RATE BASED ON INVOICE COST OF CEMENT Autoclave Expansion 0.08 12.5% per 0.01% deviation Fineness by air permeability 10 20% per 2% deviation Air Content for Non- Air Entrained Cement ± 8 0-4 free, thereafter 25% Per 1% Deviation Compressive Strength 15 20% per 3% deviation Time of Set 20 25% per 5% deviation Magnesium Oxide (MgO) 0.3 33.3% per 0.1% deviation Sulfur Trioxide (SO 3) 0.4 0.1% free and then 33.3% per 0.1% deviation Loss on Ignition 0.75 20.0% per 0.15% deviation Insoluble Residue 0.75 20.0% per 0.15% deviation Tricalcium Aluminate (C 3A) 1.5 33.3% per 0.5% deviation Silicon Dioxide (SiO 2) 3.0 33.3% per 1% deviation Aluminum Oxide (A1 2O3) 1.0 20.0% per 0.2% deviation Ferric Oxide (Fe 203) 1.0 20.0% per 0.2% deviation 801-3 SECTION 802 ADMIXTURES FOR CONCRETE
