Creating Artificially Cemented Sand Specimen with Foamed Grout

It has been shown by researchers that small amount of cementation greatly strengthens and stiffens sands. These improvements help stabilize slopes against earthquake shaking and stabilize loose, saturated sand deposits against liquefaction. Grouting practice and most grouting research has dealt with saturation grouting, however recent research has shown that partial filling of void space with cementitious grout improves strength and stiffness of sand in a very favorable way and at a low cost per unit volume. Upto now there has been no way to artificially create partial void volume grouting of sand except by physical mixing. This paper describes one way of achieving this result by the injection process using a foamed sodium silicate grout.
