This shall include the sources, product data and specifications of any proposed <br />admixtures, together with certification of compatibility of all the concrete mix components, <br />including the water that will be used. These same components shall be used during <br />construction of the bulkhead. <br />The Contractor shall also provide in this submittal, laboratory test data and trial mix data <br />from a qualified Testing Facility approved by the Engineer for the proposed concrete to be <br />utilized for the bulkhead, including, but not limited to; <br />• Compressive strengths at 7 and 28 calendar days respectively. Perform at least three <br />tests for each time increment. <br />• Slump Flow Value for each mix. <br />• Air Content. Perform at least three tests. <br />• Density. Perform at least three tests. <br />• Perform all tests at 70° F. <br />• Test data confirming the sulfate resisting properties of the concrete and its ability to <br />contain the mine water without significant degradation. <br />• <br />03300-2 <br />
