The study of nanomaterials is a recent branch of research, mainly in Brazil, considering that investments in this area only started in the 2000s. In the civil construction sector, the aim is to optimize the existing properties or add some necessary characteristic to the materials, as, for example, in cement mixtures, paintings, glass or steel. This can be achieved through the addition of nanoparticles of various elements, such as nano-silica, nano titanium and carbon nanotubes. These combinations of materials generate characteristic characteristics such as increased mechanical strengths, photocatalytic properties for environmental purification, increased elasticity modulus, in addition to decreased porosity in the case of cement mixes. In short, the addition of these particles to the materials traditionally used in civil engineering has several benefits in their characteristics, since it enables greater performance, as well as a reduction in cement consumption and evidences the existence of beneficial properties to the environment. However, the high cost of production of the materials is still a factor that limits its use in a more common way in day-to-day. In this work, we present a bibliographic review study on three nanoparticles that are being evaluated for their application in civil construction, namely carbon nanotubes, nano-silica and nano titanium, each containing its particularities and benefits.
