Experimental study of applying colloidal nano Silica in improving sand-silt mixtures
Passive method is a new procedure in stabilizing loose soils. This methodology is a type of interlocking soil particles structures. In order to optimum improve in this method, it is necessary to achieve proper penetration length and increase the shear strength of parameters. Researches have shown an increased resistance to liquefaction and decreased permeability due to colloidal Nano silica inj...

متن کاملNovel Processing of Silica Hydrosols and Gels
The extensive research activity on sol-gel processing of silica glass has been reviewed by several authors [l-4]. The typical alkoxide route to silica sols comprises the catalyzed reaction of tetraethoxysilane (TEOS) and water in a mutual solvent. The TEOS alkoxy groups hydrolyze to form silanol monomers which condense and crosslink to form the silica gel network. The nature of the sol and the ...
متن کاملFacile and economic method for preparation of nano-colloidal Silica with controlled size and stability
This study is focused on synthesis of nano-colloidal silica via alkaline water glass solution. Sodium ions of water glass were removed by cation exchanging in a resin column to obtain the silicic acid which was titrated to the solution of sodium silicate. Concentration of the colloidal silica and pH value of the solutions were controlled using different concentrations of alkaline sodium silicat...
