Abstract
Geopolymers are high-performance, cost-effective materials made from industrial waste
that ideally fit the needs of 3D printing technology used in construction. The novelty of the present
work lies in the investigation of methods to mix geopolymer concrete from fly ash (FA) class F,
ground granulated blast furnace slag (GGBS), and raw calcined kaolin clay (RCKC) to determine
the mixing procedure which provides the best mechanical strength and structural integrity. The
experimental results show that aluminosilicates with different reaction parameters when mixed
one after another provide the optimal results while the geopolymer concrete possesses the highest
compressive strength and the denser structure. The results demonstrated that the reactivity of GGBS,
FA, and RCKC increased for different depolymerization speeds of the selected aluminosilicates. This
research will provide results on how to improve the mixing order for geopolymer synthesis for 3D
printing demands. The highest compressive strength and denser structure of geopolymer concrete is
achieved when each type of aluminosilicate is mixed with an alkaline medium separately.
