Abstract To avoid the defect of traditional binders， which would lose strength under high temperatures， the geopolymer system material was used as the binder to ensure the high temperature performance of cold-bonded pellets. Chemical analysis， XRD and FR-IR were used to analyze the raw materials performance of the metakaolin-water glass geopolymer system binder. The effect of preparation parameters， such as the curing temperature， the curing time， the n（H2O）/n（Na2O），the n（Na2O）/n（SiO2）and the n（SiO2）/n（Al2O3） on the strength of pellets were studied to obtain optimized parameters. Then the strength variations of pellets under high temperatures were also discussed. The results showed that， the strength of pellets prepared under the optimal conditions was 402.4 N/P， which could meet the requirement of the actual production. Moreover， when pellets were roasted under the inert atmosphere， the strength of pellets increased with the increasing of the temperature， and the strength increased more significantly under higher temperatures. The results indicated that geopolymer binder would not lose its strength under high temperatures， and increase temperature was conductive to the strength promotion.

Key words： geopolymer binder preparation parameters optimization compressive strength high temperature strength
