Geopolymer: A Comprehensive Overview of its History, Science, and Technology
Geopolymer is a material that has been developed over the past four decades by various researchers and innovators around the world. Geopolymer is an inorganic polymer that is synthesized by activating aluminosilicate materials such as fly ash, slag, metakaolin, and rice husk ash with alkaline solutions. Geopolymer has a unique structure and composition that can be tailored to different purposes and requirements. The history, science, and technology of geopolymer can be summarized as follows:
History: The concept of geopolymer was first proposed by Joseph Davidovits in 1978, who coined the term and founded the Geopolymer Institute. Davidovits also suggested that ancient civilizations such as the Egyptians used geopolymeric materials to build their monuments. Since then, many researchers and innovators have contributed to the development and advancement of geopolymer science and technology.
Science: The science of geopolymer involves the understanding of the chemical reactions, mechanisms, kinetics, thermodynamics, microstructure, properties, and performance of geopolymeric materials. The science of geopolymer also involves the characterization and optimization of the raw materials, activators, additives, curing conditions, and processing methods of geopolymeric materials.
Technology: The technology of geopolymer involves the application of geopolymeric materials to various fields and sectors such as construction, waste management, aerospace, ceramics, coatings, adhesives, art, archaeology, medicine, energy storage and conversion etc. The technology of geopolymer also involves the innovation and commercialization of geopolymeric products and processes that can create value-added solutions for various challenges.
