The paper presents the changes in the compressive strength and mass of specimems during the soaking time in different chemical liquids to evaluate the durability of geopolymer mortar using expanded polystyrene (EPS). Experimental results on the changes depend on the mortar proportion, workability and corrosive environments. The compressive strength of geopolymer mortar tends to increase after 8 week and decrease in the coming weeks but still maintain a compressive. Experimental results showed this lightweight geopolymer mortar resistant to corrosion. This study showed that geopolymer mortar using expanded polystyrene (EPS) can be applied for making lightweight unburn-bricks existing in different corrosive environments.
