<br />03300 - 3/22 <br />2. Test data relating to the cement, aggregate, and admixtures shall be less than <br />six months old. Furnish the submittals in accordance with ACI 301 for the <br />following: <br />a. Mill tests for cement. <br />b. Admixture certification. Chloride ion content shall be included. <br />c. Aggregate gradation test results and certification. <br />d. Delivery Tickets: <br />3. Where ready-mix concrete is used, the CONTRACTOR shall furnish delivery <br />tickets at the time of delivery of each load of concrete. Each ticket shall show <br />the state certified equipment used for measuring and the total quantities, by <br />weight, of cement, sand, each class of aggregate, admixtures, and the <br />amounts of water in the aggregate added at the batching plant, and the amount <br />allowed to be added at the Site for the specific design mix. In addition, each <br />ticket shall state the mix number, total yield in cubic yards, and the time of day, <br />to the nearest minute, corresponding to the times when the batch was <br />dispatched, when it left the plant, when it arrived at the Site, when unloading <br />began, and when unloading was finished. <br />B. Other <br />1. The CONTRACTOR shall submit materials and methods for curing. <br />2. The CONTRACTOR shall submit product specifications, data, and installation <br />instructions for all miscellaneous products called for in this specification. <br />1.05 QUALIFICATIONS: <br />Truck mixers shall be equipped with electrically actuated counters by which the number of <br />revolutions of the drum or blades may be readily verified. The counter shall be of the resettable, <br />recording type, and shall be mounted in the driver's cab. The counters shall be actuated at the <br />time of starting mixers at mixing speeds. <br />1.06 CERTIFICATIONS AND TESTING: <br />A. General <br />1. Concrete and other materials for testing shall be furnished by the <br />CONTRACTOR, and the CONTRACTOR shall assist the ENGINEER in <br />obtaining samples, and disposal and cleanup of excess material. <br />2. The testing laboratory will meet or exceed the requirements of ASTM C 1077. <br />3. The cost of trial batch, laboratory, and shrinkage tests on cement, aggregates, <br />and concrete, will be the CONTRACTOR'S responsibility. <br />B. Trial Batch and Laboratory Tests <br />1. Tests for determining slump shall be in accordance with the requirements of <br />ASTM C 143. <br />2. Testing for aggregate shall include sand equivalence, reactivity, organic <br />impurities, abrasion resistance, and soundness, according to ASTM C 33. <br />3. A testing laboratory approved by the ENGINEER shall prepare a trial batch of <br />each class of concrete, based on the preliminary concrete mixes submitted by <br />the CONTRACTOR. During the trial batch the aggregate proportions may be <br />adjusted by the testing laboratory using the two coarse aggregate size ranges <br />to obtain the required properties. If one size range produces an acceptable
