The influence of curing conditions on the properties and microstructures of the geopolymers was further investigated. The compressive strength of the various geopolymer formulations were determine after curing to ascertain its utilization for the production of low-cost energy-saving geopolymer products. Results of the compressive strength of the 100% kaolin formulation (B100) was 22.88 N/mm2 at 14 days and 32.73 N/mm2 28 days respectively which showed that the strength of the produced Geopolymer improved as the curing day increases. Result of X-ray Fluorescence spectroscopy showed the following elements Si, Al, Fe, Ti and heavy metals such as Co, Zr, Pd, Pb, Y, Nb, Au. However, Mg, K and Ca were not detected as reported by previous studies. The result of the amount of the reactive elements (Si and Al) gave Si as 49.55 and Al as 11.06 for the raw Kaolin; Si as 46.27 and Al as 12.13 for the calcined Kaolin and Si as 63.82, Al as 29.14 for the produced geopolymer. The Si: Al of the produced geopolymer is 2.08 which makes it a polysialate geopolymer with excellent geopolymeric properties, which can be considered as an important material for building, pottery and major components in material and technological industries.
