Title: Graphene-silver nanoparticles loaded cement based material improves the mechanical, antimicrobial properties

Abstract

Modern architecture was based upon new and innovative technologies of construction, particularly the use of glass, steel and reinforced concrete. Modern infrastructure requires structural components with higher mechanical strength and greater durability. Now a day’s researcher in concrete technology working on innovative composite material incorporation with nanomaterials to improve cement-based materials mechanical properties. Some such nanomaterials include nano-silica (nano-SiO2), nano-alumina (nano-Al2O3), nano-ferric oxide (nano-Fe2O3), nano-titanium oxide (nano-TiO2), carbon nanotubes (CNTs), graphene and graphene oxide despite the many available studies on the evaluation of the influence of nanomaterials on the properties of cement-based composites, the effects of some nanoparticles have not yet been fully recognized. Among the unrecognized nanomaterials is graphene-silver nanocomposite. The literature devoted to this subject is limited. This paper reviews state-of-the-art research carried out on the effect of graphene-silver nanocomposite on the properties of cement-based composites. Detailed descriptions of the processing, microstructures (hydration products), properties (hydration, workability, mechanical and functional properties, and durability).Foremost new property we found in this material, which enable the antimicrobial activity in cement based composite material.
