Bauxite residue (BR) is an industrial by-product generated during the production of alumina from bauxite ores in Bayer process. BR environmentally hostile due to it high alkalinity and fine particle size distribution. In this work, blended with NaOH subsequently reduced hydrogen, order develop intermediate material rich magnetite sodium aluminate, by doing so, enable recovery iron, aluminium as...

background: introducing new endodontic cements should await comprehensive investigations and new formulations have to be tested in vivo before applying in human beings. so, the purpose of this study was to compare the biocompatibility of new endodontic cements, calcium aluminate α-aluminate cement (caac), calcium aluminate α-aluminate plus cement (caac plus), and a mixture of wollastonite and c...

At present, the most commonly used building material is ordinary Portland cement (OPC). However, OPC has a negative environmental effect during synthesis, with the release of significant amount of CO2 greenhouse gas. The cement industry is responsible for 5-8% of total global anthropogenic CO2 emissions. Geopolymerization is a technology capable of turning industrial wastes into strong and chem...
