A PROCESS FOR CONVERSION OF BASIC OXYGEN FURNACE SLAG INTO CONSTRUCTION MATERIALS
摘要
<p>The invention provides a process for conversion of basic oxygen furnace slag into construction materials like hydraulic binder in masonry blocks, flat sheets, bricks and tiles and also as a blend in cement manufacture or as in mortar for various applications. A required quantity of fluorspar is added to the molten slag for increasing its fluidity and the mixture is allowed to cool. The slag is then crushed to -3 mm size and any metallic fraction is separated using a magnetic separator. The -3 mm size non-metallic slag is ground to about 3000-4000 blain depending upon the application for which it is required. A desired quantity of gypsum can be mixed with the non-metallic fraction of the -3 mm slag before grinding.</p>
