Evaluation of Tests for Toughness/Abrasion Resistance and Durability/Soundness of Coarse Aggregates

摘要

Many tests have been developed to empiricallycharacterize aggregate without necessarily strong relationshipswith the performance of final products incorporating theseaggregates. This seems to be particularly true for "toughness andabrasion resistance" and "durability and soundness."Toughness/abrasion resistance and durability/soundness ofaggregate are correlated, but represent resistance to degradationwhen subject to mechanical forces and weathering, respectively.A literature review identified five toughness/abrasion resistanceand four durability/soundness test procedures. Sixteen aggregateswith a wide range of properties were tested with eight of theidentified test procedures. Results from the tests and testprocisions were compared.
