 The field of concrete science is multidisciplinary and utilizes nanotechnology to enhance understanding of concrete behavior, engineer its properties, and lower production and ecological costs of construction materials. Recent research at the National Research Council Canada has shown potential for improving concrete properties by modifying cement hydrates, adding nanoparticles and nanotubes, and controlling admixture delivery. This article reviews these innovative achievements in concrete materials research. This article was authored by Taijiro Sato, John Makar, Rahala Elisade, and others.
