In the production of geopolymer the use of commercial sodium silicate is very common; however this material causes several environmental impacts during its production. The extraction of silica from rice husk ash by using the alkaline lixiviation method is an alternative. In this study the storage time was analysed in the production of a source of dissolved silica more environmental friendly. The results showed all these conditions are important in the production of the alternative sodium silicate.
