Aimco Abrasion Resistance of Concrete, For Metal

To determination of abrasion resistance characteristics of concrete under physical effects only�by subjecting it to the impingement of air-driven silica-sand using l0-cm concrete cubes. Working Principle: - The surface of the concrete cubes is subjected to impingement of an abrasive charge. As a�result, abrasion of the concrete surface of the cubes occurs and resulting loss in mass of the�cubes is taken as the abrasion loss of concrete. Technical Features: - � A high carbon steel nozzle, dia 1.7 � 0.006 cm� Internal diameter of the NozzIe tip 0.8 � 0.003 cm.� Nozzle along with the tip is 15 cm� Distance b/w Nozzle tip and concrete surface is 5 � 0.02 cm.� Air pressure shall be 0.14 N/mm2,� Charge quantity each impingement is 4000 g� Abrasion charge 10 kg
