Durability is that property of concrete which plays the prime role in governing lifespan and serviceability a structure with regard to its intended usage. Environmental conditions surroundings are main criteria decide longevity performance concrete. For understanding durability structures, analysis impact chemical attacks may be crucial. As sulphate predominant on their study can interpret it w...

Introduction Our earlier investigations demonstrated that formation of hydrocarbons such as polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), polycyclic aromatic hydrocarbons (PAHs), popychlorophenols (PCPhs) and polychlorobenzenes (PCBzs) and their toxic equivalent quantity (TEQ) with dioxin-free flyash and unburnt hydrocarbon with varied temperatures as well as different hydro...

A unique process for regenerating calcium-based sorbents which are in the form of calcium sulfide was demonstrated by employing thermogravimetric analysis (TGA). The process converts calcium sulfide to calcium oxide by subjecting particles of the material to repeated cycles of oxidation and reduction at temperatures between 950 and 1100 °C. During each cycle a small portion of material is first...
