The chapter reports on a study of the effect of multi-walled carbon nanotubes (MWCNTs) when used as dispersed reinforcement on the fracture properties and microstructure of alkali-activated materials. The amount of MWCNTs added varied in the range of 0.05–0.2% of the mass of aluminosilicate precursor. Mechanical and fracture properties were determined using fracture tests carried out on 40 × 40 × 160 mm specimens with a central notch. The observed parameters were compressive strength, modulus of elasticity, effective fracture toughness and specific fracture energy. Specimen response during fracture tests was also monitored by means of acoustic emission, and this method was also used for the determination of cracking tendency due to autogenous and drying shrinkage occurring during the hardening process.
