Instead, it relies on materials rich in silica (SiO\u2082) and alumina (Al\u2082O\u2083) as its main components. Common sources of these elements include fly ash, metakaolin, and slag. These materials undergo a chemical reaction with alkaline activators to form geopolymer binders.<\/p>\n<p>There are two main types of alkaline activators used in this process:\u00a0<strong>sodium hydroxide (NaOH)<\/strong>\u00a0and\u00a0<strong>sodium silicate solution (Na\u2082O\u00b7nSiO\u2082)<\/strong>. These are widely available and cost-effective compared to other alkaline chemicals. The activators initiate a process called\u00a0<strong>geopolymerization<\/strong>, which transforms the raw materials into a strong, durable binder.<\/p>\n<p>The performance of the geopolymer depends on the ratio of the materials used. A commonly used sodium silicate solution has a\u00a0<strong>SiO\u2082\/Na\u2082O molar ratio between 1.50 and 2.50<\/strong>. A higher ratio increases the silica content in the system, affecting the viscosity and gel formation of the geopolymer. Additionally, materials such as sand, fibers, or special additives can be included to enhance specific properties.<\/p>\n<p>Key Properties of Geopolymers:<\/p>\n<ul>\n<li>Fire resistance<\/li>\n<li>Chemical resistance<\/li>\n<li>Low carbon emissions<\/li>\n<li>High strength<\/li>\n<li>Environmentally friendly<\/li>\n<\/ul>\n<p>These advantages have led to growing interest in geopolymers across various industries, including:<\/p>\n<ol>\n<li>Construction\u00a0\u2013 Used in concrete, bricks, and chemical-resistant surfaces<\/li>\n<li>Chemical industry\u00a0\u2013 Suitable for factory floors, chemical tanks, and leak-proof barriers<\/li>\n<li>Fireproofing\u00a0\u2013 Acts as insulation in buildings and vehicles; also used in fire-resistant bricks<\/li>\n<li>Structural repair\u00a0\u2013 Ideal for repairing floors, bridges, and pipelines<\/li>\n<li>Aerospace\u00a0\u2013 Lightweight and fire-resistant materials for aircraft or spacecraft<\/li>\n<li>Specialized structures\u00a0\u2013 Suitable for underground or marine applications<\/li>\n<\/ol>\n<p>Geopolymer is considered a high-potential material for the future due to its environmental benefits, sustainability, and ability to meet specialized industrial demands.<\/p>\n<hr \/>\n<h6>References:<\/h6>\n<ol>\n<li><em>Meskhi, B., Beskopylny, A.
