Testing Concrete Strength and Durability | Port Aggregates

Aug 27, 2020· Testing concrete durability. After you’ve tested the strength of your concrete, you can begin testing its durability. This is a lot more difficult to define, however, it can be determined by testing the permeability of your mix. When water seeps into your concrete, your chances of premature deterioration increase immensely.Manual of Aggregate and Concrete Testing,Practice C 1077, for Testing Concrete and Concrete Aggregate for Use in Construction and Criteria for Laboratory Evalua-tion,2 identify and define the duties, responsibilities and re-quirements for personnel and equipment used in the testing and inspection of concrete and related materials. 2.2 The Cement and Concrete Reference Laboratory7 LAB TESTS ON AGGREGATE TO CHECK QUALITY FOR USE IN,an aggregate for use in concrete on a particular job or in meeting a particular specification should be based upon specific information obtained from tests used to measure the aggregate’s quality or, more importantly, its service record, or both.
