Research and field experience have shown that fines free of clay and other harmful materials can be non-detrimental, and even beneficial, for concrete properties. A proposed new ASTM International standard will be used to distinguish between harmful and non-harmful fines in construction aggregate. ASTM WK36804 , Test Method for Rapid Determination of the Methylene Blue Value for Fine Aggregate…

Piston ring/liner interface can contribute as much as half the total friction loss in internal combustion engines, with the resulting wear leading to reduced energy efficiency and raised emissions. A new ASTM International standard provides a method to more accurately measure small amounts of wear on curved piston ring segments and their counterfaces after lubricated bench-scale testing. “Coupled…
