NANOTECHNOLOGY IN CONCRETE MATERIALS - A POWERFUL MACRO-MATERIAL INFLUENCED BY ITS NANO-PROPERTIES
Abstract
A wide range of researches demonstrated that the application of nanotechnology can improve the performance of other traditional construction materials, such as concrete, steel, glass, paint, coatings, insulating materials, et. al. Noteworthy improvements in concrete strength, durability and sustainability are being achieved with considered use of metal/metal oxide nanoparticles and engineered nanoparticles (carbon nanotubes and carbon Nano-fiber), and environment-responsive anticorrosion coatings formed using Nano encapsulation techniques are showing promise in laboratory settings. The concrete is the most nanostructured multiphase worldwide fame composite material.It is composed of an amorphous phase, nanometer- to micrometer-size crystals, and bound water. Mostly the mechanical behavior of concrete materials depends on structural elements and phenomena which are effective on a micro- and nanoscale. The ability to target material modification at the nanostructural level promises to deliver the optimization of material behavior and performance needed to improve significantly the mechanical performance, volume change properties, durability and sustainability of this remarkable and wavering material. The purpose of this paper is to show the influence of different types of nanoparticles (such as Silica fume, Titanium Dioxide Nano-powder, Carbon Nanotube etc.) on the physical and mechanical properties of concrete, as well as their subsequent influence on its behavior.
