A study on geopolymer composites based on waste from wind turbine blades

Abstract

Circular waste management is the answer to the daily waste of all types. Wind power plants installed in the 1990s are ending their service life of turbine blades, hence the need to properly manage this waste. The aim of the article is to investigate the mechanical properties of mining and industrial waste The article presents the results of research on geopolymers based on coal shale of the Staszic mine and waste from wind turbine blades in three types of compositions: 50/50, 72/25, 25/75. The results of the research show that these materials can be used as fillers for products that do not require high strength values.

Sustainable Geopolymer Structural Insulation Panels Obtained with the Addition of Power Plant Ash and Furnace Slag with Potential Uses in the Fabrication of Specialized Structures

“…Therefore, in order to reduce the consumption of raw materials and energy, in recent years, emphasis has been placed, on a global scale, on the reuse of materials produced as waste in other technologies, with their possible integration into construction materials [9][10][11][12][13]. A simple technique of increasing interest that can generate construction materials with similar properties to concrete or Portland cement-based mortar and, at the same time, integrate critical raw materials as a raw material source, is geopolymerization [14][15][16][17]. Geopolymerization is the chemical reaction of dissolving a material rich in silicon and aluminum oxides under the action of an alkaline solution and forming a Si-O-Al tetragonal structure by partially removing water.…”

Influence of elevated temperatures on the mechanical properties of foamed geopolymer materials

“…The most commonly used materials for geopolymerization are fly ash, metakaolin, slags [14–16]. Researchers are also investigating the possibility of using waste materials for geopolymerization, which also has environmental benefits [17–19]. The basic foaming agents used in the geopolymer matrix are aluminum powder or hydrogen peroxide, also silica fume or sodium peroxide [20–23].…”
