Influence of nano-silica and sodium silicate on the ...

Aug 23, 2021  Effect of curing period on nano-silica- and sodium silicate-treated clay soil. Figure 8 shows the UC strength (kPa) of clay soil treated with 4% SS with various dosages of NS over different 1, 3 and 7 days of curing periods. From the figure, it is clear that the curing period has a serious influence on the UC strength of treated clay soils.

Sodium Silicate - Minnesota Clay Home Page

Sodium Silicate. Description. The most popular deflocculant used in casting slips for many years. It is nearly always used with soda ash (when employed alone it can make a slip 'stringy' and thixotropic). The material is effective, reliable and inexpensive. However, it attacks the plaster in molds much more than more modern deflocculants and it ...
