2014-9-15 · 3. Results and Discussion. The size-fractionated aerosol and dust collected near the Hayden mining and smelting site clearly shows a bimodal distribution for both Pb and As, with maxima located at approximately 0.32 and 9.9 μm diameter (Figure 2).Scanning electron micrographs of fine particles (< 1 μm) show that particles containing relatively high concentrations of Pb and As are spherical ...
The increase in the slump is owing to the low water absorption (0.11%) and high relative density of copper slag . The replacement of sand with copper slag was adopted by weight, and hence the volume fine aggregate is lesser in the copper slag used concrete than river sand based concrete.
A comparative study of the adsorbents prepared from several industrial wastes for the removal of 2-bromophenol, 4-bromophenol and 2,4-dibromophenol has been carried out. The results show that maximum adsorption on carbonaceous adsorbent prepared from fertilizer industry waste has been found to be 40.7, 170.4 and 190.2 mg/g for 4-bromophenol 2-bromophenol and 2,4-dibromophenol, …
2016-7-28 · The concept of replacement of natural fine aggregate by quarry dust which is highlighted in the study could boost the consumption of quarry dust generated from quarries. By replacement of quarry dust, the requirement of land fill area can be reduced and can also solve the problem of natural sand scarcity.
