Geopolymers are a class of aluminosilicate materials synthesized by alkaline or alkali-silicate activation solid alumina- and silica-containing precursor at ambient higher temperature. These products have highly significant commercial technological potential, but the exact physicochemical nature geopolymeric binder phase has never before been determined. Through analysis existing experimental results from literature comparison with related systems, in particular hydrothermal synthesis...
Geopolymerization is a general term to describe all the chemical processes that are involved in reacting aluminosilicates with aqueous alkaline solutions produce new class of inorganic binders called geopolymers. In present work, novel analytical procedure developed study geopolymerization amorphous real time. This involves first conducting series well-designed leaching experiments, within which an aluminosilicate alkali-activated varying alkalinities and soluble silicate dosages. The...
In geopolymeric gels, aluminum is known to have tetrahedral coordination and be associated with an alkali cation satisfy electronic neutrality. However, the mechanism of incorporation effects different synthesis parameters are not well understood. 2H, 27Al, 23Na MAS NMR techniques been used elucidate structural properties in metakaolin-based geopolymers. Na+(aq) Al(OH)4-(aq) species were detected pore solution geopolymers Si/Al ratios ≤1.40 found directly related concentration soluble...
