“…Due to the fact that any material rich in aluminium plus silicone as shown in Figure 3, can be utilized as raw materials, there are also other numerous materials that can as well be used to produce geopolymers. For instance kaolinite which was the first material extensively utilized in geopolymer synthesis [29], then after efficaciously uses of this innovative material, the scientists start producing other novel raw materials, like calcinated clays [30]; or industrial waste (for examples slag [27]; ashes [31], waste glass [32], aluminium mine tailings (etcetra), as well as natural silico-aluminates (for instance pure Al 2 O 3 -2SiO 2 powder) [7], zeolites [22,25], etc. ).…”

The paper discusses geopolymerisation which is a chemical reaction within an alkaline solution as well as a solid reaction of both aluminium and silicon. It highlights the origin of silicates, pozzolanic composite or alumino-silicates that could be melted within alkaline solution that may be utilized as a source of geopolymers creation. Materials that possess plenty aluminium, silicon and others such as metakaolin, microsilica, pozzolanas, ashes, red mud, kaolin clay and slags can be used as raw materials with the activators to create geopolymers. Also geopolymer end product after the exothermic procedure carried out via oligomers, as well as three stages of geopolymerisation which are suspension, when hard or solid alumino-silicates matter and stuff is dissolved because of the occurrence of water together with alkali activator. After jettisoning a small quantity of water, the reorientation outsets, and then the cluster atoms take their position in the structure. In the course of the solidification at 200C (twenty Celsius degree) or higher temperature of roughly 10000C, the water (H2O) is almost absolutely jettisoned and the material displays his final look.

The present work studies the effect of solid-to-liquid (S/L) ratio on the properties of thin fly ash-based geopolymer. The fly ash geopolymers with dimension of 160 mm × 40 mm × 10 mm were synthesised by using various S/L ratios (1.5, 2.0, 2.5, 3.0 and 3.2). The alkali activator was prepared by mixing 10M sodium hydroxide (NaOH) solution and sodium silicate (Na2SiO3) with the Na2SiO3/NaOH ratio of 2.5. The samples were cured at 60°C for 6 hours. The performance of fly ash geopolymers was evaluated by testing the flexural strength after 28 days. Results showed that the S/L ratio had an effect on flexural strength. The optimum flexural strength of 5.12 MPa was achieved by the fly ash geopolymer with S/L ratio of 2.5. However, the flexural strength dropped with higher S/L ratio as the workability decreases. However, further experimental lab work should be carried out as there is less knowledge in the study on the flexural strength of thin fly ash geopolymer.
