Preparation of UHPC with Iron Ore Tailing Powder as Mineral Additive

Mechanical Properties of Low Plasticity Clay Soil Stabilized with Iron Ore Mine Tailing and Portland Cement

Due to economical and environmental issues, utilization of mineral wastes, e.g. iron ore mine tailing (IOMT), as road materials can be recommended as a sustainable alternative. In the present study, mechanical properties, as well as resistance to freezing and thawing cycles (F-T) of low plasticity clay soil stabilized with different percentages of Portland cement (0, 6, 9, 12 and 15%) and diffe...

environmental effects of gol-e-gohar iron ore mine on groundwater of the area

gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...

Onion powder as feed additive in Procambarus clarkii culture

120 days trial was performed to evaluate the effect of dietary onion powder on the growth performance of red swamp crayfish Procambarus clarkii. Crayfish with initial body weight of 1.37±0.13 g were randomly stocked to experimental tanks. Four different onion powder levels in ratios of 10, 20, 30, and 40 g/kg were added to the formulated experimental basal feed and a control group was fed with ...

The preparation and tribological properties of surface modified zinc borate ultrafine powder as a lubricant additive in liquid paraffin

This paper investigates the effects of surface modification of zinc borate ultrafine powders (ZB UFPs) on their tribological properties as lubricant additives in liquid paraffin (LP). ZB UFPs were successfully modified by hexadecyltrimethoxysilane (HDTMOS) and oleic acid (OA). It is evident that HDTMOS modified zinc borate ultrafine powder (HDTMOS-ZB UFP) delivered a small conglomerate size, go...
