The positive effects of silica fume on the permeability, swelling pressure and compressive strength of natural clay liners

Effects of nano and micro size of CaO and MgO, nano-clay and expanded perlite aggregate on the autogenous shrinkage of mortar

“…Kalkan and Akbulut [50] stated that it is difficult to give a reaction of silica fume with clay under normal conditions. However, interpretation of chemical reactions must be explained to understand silica fume-clay modification.…”

Research on the Batch and Fixed-Bed Column Performance of Red Mud Adsorbents for Lead Removal

“…Recently, there has been an increasing emphasis on the adsorbent with low cost for the heavy metal ions removal. Most cases have also confirmed that the use of large quantities of such kind of wastes for the treatment of polluted water is an attractive and promising option with a double benefit for the environment [10][11][12].…”

“…The temperature of the suspension was maintained at 20 ±1 ° C. The initial pH of the solution was adjusted to the value 7.5 by adding NH 3 and HCl. Samples were taken after mixing the adsorbent and Pb 2+ ion bearing solution at pre determined time intervals (5,10,20,30,60, and 120 min) for the measurement of residual metal ion concentration in the solution and to ensure equilibrium was reached. After specified time the sorbents were separated from the solution by centrifuge and filtration through the filter paper (Whatman grade6).…”

Effect of Fly Ash on Geotechnical Properties of Local Soil-Fly Ash Mixed Samples

“…It is accepted by Kumar (2004) and Prakash and Sridharan (2009) that specific gravity value of pond ash amended soil and coal ashes are less than soil.The affinity of non-plastic fly ash to react (flocculation/agglomeration) with soil and reduces the plasticity of soil-fly ash mixtures as observed by Goh and Tay (1993), Show et al (2003), and Kalkan and Akbulu (2004). Many previous researchers have explained the reason behind variation in MDD and OMC in soil-fly ash mixed samples on laboratory experiments as revealed by Osinubi (1998), Kalkan and Akbulut (2004), Kumar and Sharma (2004), and Kumar (2004). Effect of pond ash studied by Kumar (2004) on variation of initial void ratio and initial degree of saturation.…”
