This book investigates geopolymers and geopolymer-based composites, with a focus on their preparation, geopolymerization mechanisms, microstructures, mechanical properties, and fracture behaviors. Geopolymers are inorganic materials consisting of tetrahedral units (such as [SiO4] and [AlO4]) linked by shared oxygens and forming long-range, covalently bonded and amorphous frameworks. Geopolymers have the advantages of low-temperature preparation, low cost, high heat and corrosion resistance, and being environmentally friendly. Using the preparation methods for epoxy-based composite, they can easily be formed into complex shapes or structures. 

Intended for researchers investigating geopolymers and their matrix composite materials, this book is also a valuable resource for engineers from various fields, such as materials, mechanical, civil and structural engineering, as well as students interested in other kinds of inorganic materials or even cementitious materials in general.

This book mainly provides a comprehensive treatment of the SiBCN ceramics and their matrix CMCs, aspect of theme content including material design and preparation, microstructural feature and evolutionary process, mechanical and thermophysical properties, resistance to oxidation, thermal shock and ablation, and the mechanisms of oxidation, ablation and crystallization of SiBCN-based materials. Furthermore, this book offers the necessary fundamentals to ensure a basic understanding of the structure and properties of metastable Si-based ceramics and their composites for undergraduate and postgraduate students in materials-related disciplines in higher education, as well as for scientific research, production development and technical management in the fields of metastable materials, mechanical alloying processing nonequilibrium structure, organic-inorganic composites, etc.
