Incorporação de nanopartículas em compósitos cimentícios, uma pesquisa bibliográfica

Abstract

The civil construction industry is constantly looking for building elements and new technologies for the improvement of the sector. The modification of cementitious composites with nanoparticles can be one of these technologies, since nanoparticles have unique properties and, when used in cement pastes, it can result in a new material with superior qualities to conventional ones. This work aimed to analyze studies of authors who used magnetic nanoparticles, carbon nanotubes or nanosilica and evaluated their influence on the properties of cementitious compounds. Thus, bibliographic research was made about the respective nanoparticles mentioned, their synthesis, workability, hydration, and quantitative analysis of the composites' resistance to compression, traction and bending. Through representative images, tables of results and graphs, a conclusion was reached, such as the improvement of the mechanical properties of the composites and the need for further studies, regarding these nanomaterials as modifiers of cement pastes.
