Clean technology for sustainable development by geopolymer materials

Abstract

Geopolymer materials have captivated as a promising material for building restoration due to their environmentally sustainable nature as well as their potential to use a variety of waste products as precursors. Numerous industrial, municipal and agricultural wastes can be used to create environmentally acceptable, sustainable, structurally sound geopolymer matrices. These new generation materials, fabricated by following the geopolymerisation reactions of alumino-silicate oxides with alkali activators, have the advantages of high mechanical strength, corrosion resistance, durability, fire resistance etc., and can serve as a substitute for construction materials like Ordinary Portland Cement since they carry enormous impact on the environment. This review presents the importance of geopolymeric materials and their role in sustainable development giving special emphasis to kaolin, metakaolin, zeolite, fly ash, dolomite, red mud and clay based geopolymer materials.

Review of Geopolymer Nanocomposites: Novel Materials for Sustainable Development

“…The main benefits from this fact can be achieved through the large-scale application in the building industry as infrastructure projects. It is also worth mentioning that the fabrication of geopolymer-based concretes and cements produces significantly lower carbon dioxide emissions compared to the fabrication of Portland cement, which is undoubtedly favorable in terms of environmental protection and phenomena affecting climate change (including the greenhouse effect) [184][185][186][187][188][189]. Geopolymers belong to a group of rapidly developing materials.…”

Tunable Thermal Conductivity of Sustainable Geopolymers by the Si/Al Ratio and Moisture Content: Insights from Atomistic Simulations

“…The traditional cement production process requires high-temperature calcination, which is a carbon-intensive process that releases a large amount of carbon dioxide and has a negative impact on climate change . In contrast, the preparation process of geopolymers involves chemical reactions at lower temperatures, thus reducing energy use and associated carbon emissions, and the carbon footprint can be further reduced by selecting alkaline activators. , At the same time, geopolymers also have many other advantages, such as excellent mechanical properties, fire resistance, chemical corrosion resistance, and so on. − In recent years, they have received increasing research attention and have been widely used in construction, chemical industry, aerospace, and many other fields.…”
