An overview of mechanical and thermal properties of nano concrete

Abstract

In This article the nanomaterial effect on concrete was discussed. Nowadays, nanotechnology has received wide attention to enhance conventional concrete properties. In contrast, the topic of this research is to find thermal insulation and related material with good mechanical properties, so nanomaterial was added to concrete mixtures to take advantage of the nanoparticle’s enhanced properties on concrete and mortar in terms of thermal insulation. In latest research, researchers have been carried out to boost the portability of concrete on thermal insulation by manufacturing lightweight concrete. As it is known to have low compressive strength, considering that the density reduction of concrete is one of the thermal insulation methods. The researchers find that using nanomaterial is a good topic in improving concrete’s mechanical and thermal properties by reviewing previous research. Also, it affirms the necessity of continuing scientific efforts to study various factors affecting nanomaterial use in concrete. The present article aims to review research that has used nanomaterials to improve the mechanical and thermal properties of concrete, identify the positive and negative aspects of using nanomaterials in concrete, and define future directions for nanotechnology in building and construction technology globally. Also includes the most important design and operational variables influencing the use of nanotechnology in concrete to reach a reliable reliability of nonconcrete technology.
