801CEMENT

801.01REQUIREMENTS. 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).

fly ash does not exceed 3.0 percent.

of tests performed on the fly ash used in the manufacture of the Type IP( ≤20) cement shipped to the project.

available for consultations on the project at any time the Engineer deems necessary, at no expense to the Department.

Engineer approves otherwise.

4) Type IS( ≤30), Portland blast furnace slag cement, conforms to ASTM C 595 and the following requirements:

of ASTM C 989.

results of the tests performed on the blast furnace slag cement used in the manufacturing of the Type IS( ≤30) shipped to the project.

available for consultation on the project at anytime the Engineer deems necessary, at no expense to the Department.

Engineer approves otherwise.

5) Type IL(5-15), Portland-limestone cement, conforms to ASTM C 595 and the following additional requirements:

of test performed on the limestone used in the manufacture of the Type IL cement

shipped to the project.

approves otherwise.

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.

801.02NON-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.

SECTION 802 ADMIXTURES FOR CONCRETE

802.01REQUIREMENTS. Provide admixtures conforming to the following

requirements:

.01 Air-Entraining. ASTM C260, except the chloride content (as Cl) shall not

exceed one percent by weight. The Department may require tests for bleeding, time of setting, and length change.

.02 Water-Reducing and Retarding. ASTM C494, Type D, except the relative

durability factor shall not be less than 90 and the chloride content (as Cl) shall not exceed one percent by weight.

.03 Water-Reducing. ASTM C494, Type A, except the relative durability

factor shall not be less than 90 and the chloride content (as Cl) shall not exceed one percent by weight.
