The present disclosure provides a potassium aluminosilicate-based nanogel precursor additive and use thereof in a low calcium system-based geopolymer, belonging to the technical field of geopolymer additives. In the present disclosure, the potassium aluminosilicate-based nanogel precursor additive has a high-activity and potassium aluminosilicate-based short-chain structure, and is a precursor of the low calcium system-based geopolymer. The additive includes K2O, SiO2, and Al2O3, and has a K/Si molar ratio of 1.0 to 4.0 and an Al/Si molar ratio of 0.25 to 1.5. The potassium aluminosilicate-based nanogel precursor additive can be added to a matrix material of the low calcium system-based geopolymer, to effectively optimize a hydration process, balance an internal reaction, and improve a pore structure of the low calcium system-based geopolymer such as metakaolin, thereby improving mechanical properties. The additive effectively avoids harsh curing conditions, uneven hydration reaction.
