A geopolymer is an inorganic, often ceramic -like material, that forms a stable, covalently bonded, non-crystalline to semi-crystalline network through the reaction of aluminosilicate materials with an alkaline or acidic solution. Many geopolymers may also be classified as alkali-activated cements or acid-activated binders. [1] .

Apr 5, 2006 · Geopolymers are chains or networks of mineral molecules linked with co-valent bonds. They have following basic characteristics: a) Nature of the hardened material: X-ray amorphous at ambient and medium temperatures; X-ray crystalline at temperatures > 500°C; b) Synthesis Routes:

Jun 1, 2021 · Geopolymers, as inorganic polymer materials, are also known as alkali-activated materials (AAMs). Geopolymers can take natural materials and waste products as the primary raw materials synthesized by alkali or acid activation reaction. Common raw materials and their abbreviations are shown in Table 1.

Nov 18, 2024 · Geopolymers are a type of inorganic polymer that form by the chemical reaction between alumino-silicate materials and alkaline activators, such as sodium hydroxide or potassium hydroxide.

Geopolymer concrete is an innovative and eco-friendly construction material and an alternative to Portland cement concrete. Use of geopolymer reduces the demand of Portland cement which is responsible for high CO 2 emission. What is Geopolymer Concrete?

Geopolymer is a product of a polycondensation reaction that yields a three-dimensional tecto-aluminosilicate matrix. Compared to unary geopolymer systems, binary geopolymer systems contain complex hydrated gel structures and polymerized networks that influence workability, strength, and durability.

Nov 1, 2023 · Geopolymer materials exhibit excellent adsorption properties due to their high specific surface area, porous structure, and ion-exchange capabilities. Geopolymers can effectively remove a wide range of contaminants from water, including heavy metals, organic pollutants, and emerging micropollutants.

Geopolymers are the class of innovative, inorganic polymeric cementitious Alumino-Silicate materials possessing an amorphous three-dimensional structure which comprises of SiO4 and AlO4 tetrahedral related by shared Oxygen atoms.

A geopolymer is a semi-crystalline amorphous material formed through the polymerization reaction between an aluminosilicate source and an alkaline reagent. The polymerization process can be induced and/or catalyzed by the application of heat. Geopolymers have been studied largely as building materials.
