发明名称 Geopolymer with nanoparticle retardant and method
摘要 A method of controlling the setting time of a geopolymer by coating aluminosilicate particles with nanoparticles to slow the geopolymerization reaction. The coating effectiveness of the nanoparticles may be enhanced by pretreating the aluminosilicate particles with a layer-by-layer assembly of polyelectrolytes. A geopolymer is formed by mixing about 39% to about 66% by weight aluminosilicate source, about 0% to about 40% by weight sand, about 19% to about 33% by weight of alkali activator solution, and about 1% to about 4% nanoparticles.

主权项 1. A method of controlling the setting time of a geopolymer, comprising the steps of: a) partially or completely coating aluminosilicate particles with nanoparticles; b) then mixing the coated aluminosilicate particles with sodium silicate and a sodium hydroxide solution to form a geopolymer through a geopolymerization reaction, wherein the nanoparticles retard the geopolymerization reaction.
