Innovative cement-based composites are recently strongly emerging
technology. Nanotechnology is one of the potential alternatives to
improve cement characteristics and to decrease the amount of cement used
in various applications, which consequently reduces the energy required
for cement production and carbon dioxide emission caused by cement
industry. In this book, some approaches for improvement of cement were
conducted. Incorporation of waste materials or small amounts of prepared
inexpensive nanomaterials was considered in this study as a viable
strategy for cement reinforcement. Iron slag as waste material and
titanate nanofibers were introduced to cement paste separately or as a
mixture to evaluate the mechanical, morphological and chemical
properties of the solidified cement blend. The produced composite
prepared from Portland cement, iron slag and small amounts of titanate
nanofibers has subjected towards several mechanical, physical and
chemical testing after drastic events; based on the elaborated results,
the new composite formulation can be suggested as matrix both for safe
immobilization of hazardous wastes and as a valuable material to be used
in building industry.
