Researchers conducted research into the strength properties of a Geopolymer produced from eggshell powder, bauxite, and flyash with RGL (Reaction generating liquid) cure for 84 days at ambient temperature. Also studied were changes in products Morphology, XRD, FTIR studies SEM images microstructure. The results indicated that, various mix proportions, gradually improved 28 to days. aged Geopoly...
Bauxite residue (red mud) generated during alumina production is a highly alkaline solid waste. The red mud mainly stored on land, but it can cause harm to the surrounding environment and human health. transformation of into soil feasible method for large-scale disposal mud, alkali removal key process that controls soil. In this study, calcification dealkalization with small particle size was c...
The aim of this study is to determine the stratigraphic position bauxite deposits in Ayrancı region, where most important mineralization Bolkardağı region located. In context, age will be determined by determining erosion surface associated with features during formation and according its side rocks. there are Permian-Cretaceous aged rocks belonging Union, one main tectonic units forming Centra...
Hydrocracking represents an alternative to the recycling of abundantly available plastic waste. polyethylene in a fluidized bed, at 750 °C and 1 atm, was investigated this work. Water dissociation, through steam-iron reaction, used as source hydrogen. Bauxite olivine, containing reduced iron, were bed materials reactor drive water dissociation reaction. The hydrogen-to-carbon (H/C) ratios produ...
Brazil is the richest country in the world in terms of primate species and the Amazonian rain forest is one of the richest biomes containing 15 (ca. 90%) of the Neotropical primate genera. Although considered key elements in conservation strategies, there is only anecdotal information on primates for several protected areas within the region. Here we present new data on the community compositio...
