The book presents original work on how nanomaterials are applied to concrete through electromutagenic processes, which modify the microstructure of concrete materials in situ without changing their dimensions or appearance. In essence, it shows how high-performance concrete can be mixed without expensive additives. The book offers a method for dispersing nanoparticles in concrete and explains how their presence reduces porosity, increases strength and prevents cracking - information that can be used for more efficient repair and rehabilitation. Nanomaterials are shown to improve barrier-formation, anti-corrosiveness, and other functions of concrete. Extensive practical guidelines are given on formulation, set-up, mixing, and testing. This book: explains how to modify concrete after hardening, and repair with minimal destruction. It provides engineering details on how nanoparticles relate to porosity, cracking, and corrosion. It includes scientific background and information on set-up, mixing, and testing.
