The Research on the Experiment Conditions for the Preparation of New Geopolymer by the Utilization of Tailings

Abstract:

Admix different tailings for preparing new inorganic mineral polymer. To explore the preparation conditions by testing the different performances of mortar specimens. The results show that, the strength performance is the best when the tailing dosage is 20%, the modulus of water glass is 1.2, water glass content (Na2O) is 4.5% and the ratio of liquid to solid is 0.6.
