The paper presents an evaluation of the potential of using the limestone powder as a substitute for the fine aggregate, focusing on the impact of such a modification on aspects of durability. The sulfate degradation and chloride ion diffusion in concrete were investigated. The overall desirability function has been determined.

Sep 8, 2021Ultra-fine diamond powder is an ideal abrasive for ultra-precision grinding of hard and brittle materials. 15 The hardness of diamond is higher than that of ordinary hard brittle materials. Compared with other abrasives, diamond abrasives can invade the surface of workpiece with less pressing force, resulting in mechanical removal.

This research project investigated the wheel wear and tribological characteristics in wet, dry and minimum quantity lubrication (MQL) grinding of cast iron. Water-based Al2 O3 and diamond nanofluids were applied in MQL grinding process and the results were compared with those of pure water. During the MQL grinding using nanofluids, a dense and hard slurry layer was formed on the wheel surface ...

Ball mill is a type of grinder which is used in mixing materials like ceramic, ores, paints, and chemical. These balls rotate around a horizontal axis. These balls can be made from ceramic, stainless steel, silicon carbide. Ball mills are widely used in mechanical alloying. [Florez-Zamora et.al (2008)].
