Study on the effects of alkaline-activeted solution on some properties of geopolymer concrete

Abstract

   Geopolymer concrete composition design changed the ratios of Alkaline-activated solution (NaOH và Na2SiO3) and mineral additives mixture (Blast Furnace Granulated Slag and Fly ash) respectively 0.3, 0.4, 0.5 and 0.6. To use an Alkaline-activated solution with a sodium silicate to sodium hydroxide ratio
of 2.0. The results show that when the ratio of Alkaline-activated solution increases, the strength and workability of Geopolymer concrete increases, the activation process is more thoroughly
