(r) Tests All tests will be the responsibility of the Contractor and certified test results shall be submitted to the COR. Samples will be selected on a random sample basis in accordance with ASTM C-172. If the measured slump or air content falls outside the specified limits, a check test shall be made immediately on another portion of the same load. In the event of a second failure, the concrete will be considered to have failed the requirements of the specification and the load will be rejected.

The following concrete tests will be taken:

Slump Testing will be in accordance with ASTM C-143.

Air Content Testing will be in accordance with ASTM C-231.

Compressive Tests Compressive test cylinders will be molded, cured, prepared and tested in accordance with ASTM C-31 and C-39. A minimum of three cylinders will be taken from each truckload of concrete.

The first cylinder from each set shall be tested at 7 days, the second at 28 days, and the third shall be tested immediately if the second cylinder in the set fails at less than the specified compressive strength. Test results of cylinders tested at 28 days will form the basis for acceptance or rejection of concrete strength. Each 28 day compressive test result shall be the average of the compressive test of two cylinders from the same set. A minimum of two cylinders from each batch will be evaluated in accordance with ACI 318-77, Article 4.8.2.
