Metakaolin-based geopolymer materials reinforced with sand in tubular shape were developed, and their durability in acidic, neutral and humid environment was investigated. Results show that mechanical properties of materials are not affected by durability tests suggesting a good stability in aqueous media. Furthermore, the surface of samples which was covered by soluble species such as KOH or K2CO3 becomes smooth after treatment in acidic and neutral media and appears not to be attacked confirming the high acid resistance of geopolymer materials.
