26/02/2019· Ni0.9Fe0.1Ox is the most active water oxidn. catalyst in basic media, passing 10 mA/cm2 at an overpotential of 336 mV with a Tafel slope of 30 mV/dec with oxygen evolution reaction activity roughly an order of magnitude higher than IrOx control films and similar to the best known OER catalysts in basic media.
BOF steel slag as a fine and coarse aggregate for the design of high performance asphalt concrete. Various combinations of steel slag, dolomite sand waste and conventional aggregates were used to develop AC 11 asphalt concrete mixtures. The tests of
29/12/2012· For example to cut an aluminium bar, an iron fast rotating cutter may be used. These methods involves a physical contact between the cutting tool and the material being cut or processed. Unconventional Machining processes: As the name suggest, unconventional machining method involves the use of modern and advanced technology for machine
An excellent correlation existed between the average total expansion of the fine aggregate fraction and that of the "parent" coarse aggregate.
01/09/2013· MIX DESIGN Dense graded AC mixtures were designed by using conventional and unconventional raw materials. The Marshall mix design procedure was used for the determination of the optimal bitumen content for the reference mixture, considering the mixture test results for Marshall stability and flow, as well as the volumetric values: air voids , voids
Dense graded AC mixtures have been design ed by using conventional and unconventional raw materials. The Marshall mix design procedure wa s used for the determination of the optimal
CONVENTIONAL AND UNCONVENTIONAL AGGREGATE Viktors Haritonovs, Martins Zaumanis, Guntis Brencis, Juris Smirnovs Riga Technical University, Department of Roads and Bridges E mail: [email protected] ABSTRACT Annually up to 200 thousand tons of steel slag, a non metallic co product of iron and steel production, are produced in Latvia.
