Nanomaterials in construction industry: An overview of their properties and contributions in building house

Abstract

The construction sector is responsible for 25 % of global greenhouse gas emissions and consumes 50 % of the world's energy. This paper addresses the use of nanomaterials in housing construction, comparing their influence at the technical-structural level. Materials such as titanium dioxide, carbon nanotubes, nanosilica, nanocellulose, nanoalumina, and nanoclays were analyzed. It was obtained that these nanomaterials can improve the structural, thermal, and functional properties of construction materials. In addition, they are related to increased durability, increased mechanical strength (>20 %), reduced thermal conductivity, and self-cleaning capability. Therefore, the use of nanomaterials promises to improve the sustainability and efficiency of housing construction.
