مقاله لاتین “علم و فناوری نانو در سیمان و بتن”
Abstract: Concrete science is a multidisciplinary area of research where nanotechnology
potentially offers the opportunity to enhance the understanding of concrete behavior, to
engineer its properties and to lower production and ecological cost of construction
materials. Recent work at the National Research Council Canada in the area of concrete
materials research has shown the potential of improving concrete properties by modifying
the structure of cement hydrates, addition of nanoparticles and nanotubes and controlling
۱٫ Introduction
Typical concretes consist of ordinary Portland cement (OPC), fillers such as sand, coarse
aggregates, admixtures and water. This combination of materials allows concrete to be produced in a
fluid form that can be pumped and moulded. The complex chemistry and physical structure of cement
hydrates in concrete however mean that issues of fundamental science still need to be resolved.
Research at the nanoscale has the potential to contribute to these debates and questions. Analysis at the
nanoscale may provide further insight into the nature of hydrated cement phases and their interaction

with admixtures, nanofillers and nanofibers. These interactions offer the possibility of modifying
cement reactions, creating new surface chemistries (referred to as nanoscience), developing new
products for the concrete industry (referred to as nanotechnology), and allowing a more controlled and
…ecologically friendly manufacturing route to cement and concretethe delivery of admixtures. This article will focus on a review of these innovative achievements
