Chapter 2. Materials and Methodology

Abstract
The materials and methodologies used to fabricate and characterise geopolymer composites and nanocomposites are described in this chapter. The characteristics of natural fibers, fabrics and nanofillers used for the fabrication of composites are described. The structure and properties of these materials were investigated using a wide range of techniques which include X-ray diffraction (XRD), Fourier transforms infrared spectroscopy (FTIR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and thermo-gravimetric analysis (TGA). Methodologies for evaluating flexural strength, flexural modulus, impact strength, fracture toughness, impact toughness, and water absorption are also described.

Chapter 4. Mechanical Properties

Abstract
This chapter describes the mechanical properties of geopolymer reinforced with natural fibres and/or nanofillers. Results show that the appropriate addition of natural fibres and/or nanofillers can improve the mechanical and fracture properties of geopolymer composites and nanocomposites. Results show that the mechanical properties of these materials are improved by increasing the content of natural fibres.

Chapter 5. Moisture Absorption and Durability

Abstract
This chapter describes the characteristics of moisture absorption and durabilty of geopolymer reinforced with natural fibres and/or nanofillers. Results show that the appropriate addition of natural fibres and/or nanofillers can have a profound influence on the moisture resistance of geopolymer composites and nanocomposites. The durability of these materials was ascertained by studying the effect of water absorption on their mechanical and physical properties.
