A comparative study of the utilization of synthetic foaming agent


Lightweight geopolymer concrete was synthesized using fly ash as an aluminosilicate source with the addition of a pore-forming agent. The synthesis of a geopolymer was conducted by employing various volume ratios of geopolymer paste to the foaming agent: 1:0.50, 1:0.67, 1:0.75, 1:1.00, 1:1.33, 1:1.50, and 1:2.00. In contrast, the ratios of aluminum powder weight percentage to the fly ash weight varied between 0.01 - 0.15 %wt. The results showed that the higher the foaming agent content, the lower the compressive strength and density of the geopolymer. The ratio of the geopolymer paste to the foaming agent, 1:1.33, produced the strongest lightweight geopolymer whose compressive strength and density were 33 MPa and 1760 kg/m3, respectively. With the addition of 0.01%wt aluminum powder, the geopolymer specimen showed the highest compressive strength of 42 MPa and 1830 kg/m3 density, respectively. X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), and FT-IR were utilized to study the effects of foaming agent and aluminum powder addition on the geopolymer's microstructure, surface morphology, and functional groups. Both types of synthesized geopolymers can potentially develop in terms of compressive strength and density in the future. An earthquake occurs due to the mass transfer in the rock layer of the earth, where the strength of an earthquake is affected by the amount of energy released during the shifts and collisions. Indonesia is one of the countries heavily struck by earthquakes yearly. Therefore, it is necessary to establish an advancement that may reduce the impact, especially regarding infrastructure. The selection of construction materials with lightweight structures is one of the reasonable inventions to reduce damage and safety risks.
