Abstract:	The present paper deals with the structural stability of inorganic amorphous aluminosilicate geopolymer during long-term period. The geopolymer systems have been prepared by mixing calcinated kaolines and sodium activators. Structural behavior, during ambient ageing and thermal treatment (at 100 degrees C for 1 - 4 weeks) have been monitored by XRD, solid state NMR spectroscopy, and measurement of compression strength. Growth of crystalline zeolite phases were observed after thermal treatment. These structural changes are accompanied with fluctuations of geopolymer bodies compressive strengths.
