Milling Parameter Optimization For The Manufacture of SubMicrometric Portland Cement
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 3
Abstract
Today, ultra-high-performance nanostructured concrete is being developed by using high-fineness Portland cement with blast furnace nano-slag and other nanomaterials. The primary aim of this research was to obtain the optimum milling parameters of Portland cement with an average particle size (APS) in the submicron range, by using a planetary ball mill with 5/8" and 1/2" ball diameters. The Portland cement was subjected to different grinding processes, varying the combination of the parameters, until obtaining an APS in the submicron range. The characterization for both the as-received and milled Portland cement was carried out through the following techniques: laser diffraction, XRD, scanning electron microscopy, specific surface area of the cement, and normal cement consistency. The optimum milling parameters were then analyzed and evaluated. The average particle size of the submicron Portland cement obtained through the optimal combination of the parameters was 0.84 μm
