Contrôle de l'attaque des sources aluminosilicates par la compréhension des solutions alcalines

Abstract : This study was undertaken to identify the parameters that control the geopolymerization reaction and the working properties of the final materials. To do this, various aluminosilicate sources and alkaline solutions have been studied to exacerbate their reactivity. Then a feasibility study of the consolidated materials was conducted to identify the geopolymer existence domain in Si-Al-M / O ternary diagram. The evolution of samples during formation was monitored by thermal analysis (DTA-TGA), to quantify the required energy for oligomer formation, and infrared and nuclear magnetic resonance spectroscopies to determine the nature of formed networks and the reaction rate. A strong correlation was evidenced between the precursors reactivity, the local and porous structure and the mechanical properties. The obtained results have been exploited to use poorly reactive Tunisian clay as alternative aluminosilicate source and also to reuse geopolymer waste in new formulations.
