Influence of Nanomaterials on the workability of Cement-based Concrete _ A Critical Review

Abstract

The development of nanotechnology has led to the emergence of nanomaterials as potential admixtures suitable for the enhanced workability of cement-based concrete. This review paper being presented is an overview of the latest research development on the use of nanomaterials and their influence on the workability of cement-based concrete, factors affecting workability, mechanism, potential applications and economic aspects. A detailed discussion on the three main types of nanoenhancers such as nanosilicates, carbon nanotubes and fullerenes and their properties in capable of modifying concrete workability has been carried out. In addition, the effect of particle size and concentration on the properties of the concrete has also been examined. Furthermore, this review exposes some of the key aspects of nano-admixtures applications in enhancing the workability of cement-based concrete.
