luminium based composite are getting a vast scope nowadays because of its properties and availability. In the present work, fly ash and AL2O3 reinforced composite are prepared using stir casting technique for varying wt.% (fly ash 3% and AL2O3 3%, 6% & 9%). Hardness and tensile properties were determined, with the addition of reinforcement the properties are improved compared to the parent meta...

It is necessary to reduce the effect of carbon dioxide, as failure do so will result in global warming. In this instance, researchers have begun looking for sustainable building materials. Industrial byproducts like flyash, GGBS, silica (SiO2) are used make geopolymer concrete. To produce binders alkali liquids can be react with aluminate, and activated concrete made by mixing coarse fine parti...

Cr(VI) is a highly toxic metal ion and considered a priority pollutant released from various chemical industries. Treatment methods to remove Cr(VI) from water and wastewater include chemical precipitation, ion exchange, membrane separation, electro-coagulation and reduction. These methods are not economically viable for large scale treatment of wastewater that is rich in Cr(VI). Adsorption is ...

The results of a theoretical study of the formation and growth of the submicron flyash aerosol around a single burning coal particle are presented. The vaporization of ash and subsequent aerosol formation near the coal particle are studied because the local combustion environment influences these proewes strongly. A mathematical model is developed that describes the transport of ash vapor and a...
