Introduction: In our study, various test methods were adopted to explore the mineralogical characteristics, grindability, particle morphology, size distribution, and environmental leaching toxicity of iron ore tailings (lOTs). Methods: The include petrographic analysis, X-ray diffraction (XRD), scanning electronic microscopy (SEM), synchronous thermal analyzer (DSC-TGA), electron probe microana...

The need for sustainable concrete with low carbon dioxide emissions and exceptional performance has recently increased in the building industry. Many distinct types of industrial byproducts ecologically safe wastes have shown promise as ingredients this kind concrete. Meanwhile, industrialization lifestyle modernization continue to rise, ceramic waste becomes an increasingly serious threat natu...

steel slags are the by products of steel industries, which forms during reduction process of iron melting. the chemical composition of it changes depending to the melting procedure. its mineralogical composition also varies based on the cooling procedure. two different types of steel slag were used as absorbing bed for various concentrations of pb2+ ions in the form of lead chloride, and the co...

There has been a significant movement in the past decades to develop alternative sustainable building material such as geopolymer cement/concrete control CO2 emission. Industrial waste contains pozzolanic minerals that fulfil requirements alumino-silicate based geopolymer. For example, industrial red mud, fly ash, GBFS/GGBS (granulated blast furnace slag/ground granulated slag), rice husk ash (...

Acid mine drainage (AMD) is one of the biggest issues faced by mining and mineral processing industries in terms removing heavy metals from effluents. The present study investigated effects glyoxylic acid, hydrazine dimethylamine borane as reducing agents effect using Ni, Fe, basic oxygen furnace slag (BOFS) granulated blast (GBFS) seeding materials to remove acidic effluents respectively. expe...

This paper evaluates the effect of mix design parameters on mechanical, hydraulic, and durability properties pervious geopolymer concrete (PGC) made with a 3:1 blend granulated blast furnace slag (GBFS) fly ash (FA). A total nine PGC mixtures were designed using Taguchi method, considering four factors, each at three levels, namely, binder content, dune sand addition, alkaline-activator solutio...

Materials containing ground granulated blast furnace slag (GGBFS) display a transient green–bluecolor after demolding. This greening effect has been investigated for leaching behavior and ecotoxicological impact. Color of concretes pure pastes GGBFS was assessed with portable spectrophotometer, samples were then submitted to tank monolith test. Ecotoxicological tests conducted on reference samp...

A granulometric bandpass "lter (GBF) passes certain size bands in a binary image. There exists an analytic formulation for the optimization of GBFs in terms of the granulometric size density of a random set. This size density plays the role of the power spectral density for optimization of linear "lters. An optimal "lter depends on the parameters governing the distribution of the random set. In...

This report is an analysis of the structure of the compound biological effectiveness (CBE) factor. The value of the CBE factor previously reported was revalued for the central nervous system, skin and lung. To describe the structure, the following terms are introduced: the vascular CBE (v-CBE), intraluminal CBE (il-CBE), extraluminal CBE (el-CBE) and non-vascular CBE (nv-CBE) factors and the ge...
