2. Technology description
A distinction is made between alkali silicoaluminate and soda silicoaluminate concretes, according to the reaction principle of the components.
2.1 Alkaline silicoaluminate concretes
Alkali silicoaluminate concretes result from the reaction of alkali hydroxides and/or silicates (mainly sodium) with silicoaluminous components such as blast furnace slag, metakaolin and fly ash (table 1 ).
Sodium hydroxide is obtained by electrolysis of a sodium chloride solution. The electrical current can be of hydraulic or nuclear origin. The sodium silicate solution used in this process is obtained by industrial steps involving the consumption of thermal...
