About the book
The strong technology development and the increase of population number during the past few decades has led not only to a high increase in the demand of raw materials and energy, but also in a special need of recycling and process intensification. Since recycling is seen as the most promising and cost-effective option to reduce the use of fossil energy and non-regenerable raw materials, in the industrial concept and present trends in the oxidic materials applications, geopolymers seem to meet all the criteria to replace conventional materials and contribute to a sustainable future. By applying innovative technologies, the coefficient of use of waste for developing new materials can be increased simultaneously with the decrease of the carbon footprint and the ecological impact. Accordingly, these eco-friendly materials will participate in cutting-edge research and applications due to their tailored properties, including superabsorbent capacity, heavy metals encapsulation, flame retardancy, mechanical performance, electrokinetic behaviour, corrosion resistance and thermal properties.
This book aims to join activities and knowledge of researchers from multiple fields, in order to obtain a key overview in the advances in geopolymers synthesis and characterization, including base chemistry concepts, nanoscale characterization and applications in top-level industry.
The topics are described as follow, but are not limited to:
1. Geopolymers chemistry topic describes the chemical reaction models and chemical kinetic of the geopolymerization which occurs after mixing the aluminosilicate raw materials with an alkaline solution.
2. Advanced characterization of geopolymers topic includes innovative technologies applied on geopolymers characterization at the nanoscale level, meant to explain the bond between the reacted and nonreacted particles from the composition.
3. Sustainability with geopolymers topic should provide clear information about the characteristics and applications of the geopolymers which use as raw materials industrial waste. Moreover, environmental impact studies which offer a clear view of the effects produced by geopolymers manufacturing, compared to conventional materials, is included.
4. Geopolymers as functional materials topic will present key aspects in developing geopolymers with tailored properties that increase further the heavy metals adsorption capacity, offering outstanding opportunities for energy-efficient separations and process intensification, in terms of saving energy, reducing capital costs, minimizing environmental impact and maximizing the raw materials exploitation.
5. Reinforced structures topic describe the effects produced by the introduction, in the geopolymers matrix, of different types of reinforcing elements.
