Geopolymer concrete with metakaolin for sustainability: a comprehensive review on raw material’s properties, synthesis, performance, and potential application

Comprehensive Understanding of Aluminosilicate Phosphate Geopolymers: A Critical Review

“…In addition, it seems that the obtained geopolymer structure is denser and the compressive strength is higher with the decrease in the particle size of metakaolin [ 25 ]. However, it should be noted that metakaolin is usually obtained from natural kaolin calcined at 600~900 °C to improve its reaction activity [ 26 ]. In addition, due to the slow release of aluminum in phosphoric acid solution at room temperature, ASP geopolymers face the problem of a long setting time at room temperature (usually several days).…”

Decolorization of Reactive Dyes, Part VII: Eco-Friendly Approach of Reactive Dye Effluents Decolorization Using Geopolymer Cement Based on Metakaolin-Slag mixes

“…Greater thermal insulation [24,25], bonding strength, and compressive strength [26] are all exhibited by the MKbased geopolymers. According to Jindal et al [27], have a variety of applications, such as fireproof materials needed for buildings, a sustainable concrete substitute, and an environmentally friendly material. Numerous studies have coupled the system with different materials to reduce costs, maintain excellent performance, and accomplish resource reuse since MK-based geopolymers offer better mechanical properties [28,29].The use of MK-based geopolymers as "self-cleaning" building materials is another important application area [30].…”

The Durability of Lightweight Geopolymer Concrete (LGC) on Chloride Resistance

“…The higher the concentration of NaOH used, the higher the compressive strength produced [11][12]. Geopolymers also have good resistance to extreme environments [13].…”
