Application of Nano-Additives Reinforcement towards Concrete with Excellent Mechanical Properties: A Review

Until the last decade, extensive scientific research has been conducted on the different applications of nanoparticles in civil infrastructures.Nanoparticles are defined as ultrafine particles ranging in dimension below 100 nanometers.The addition of nanoparticles is a promising approach for increasing the concrete's strength and durability, hence enhancing the concrete's quality and promoting sustainability.In this literature study, the review focuses on commonly used nanoparticles in different categories, such as carbon nanotube (CNT), graphene (GNP), nano silica (NS), nano Al 2 O 3 , nano TiO 2 , and nano clay.The review highlights the mixing method and the influence of nanoparticles on fresh and hardened concrete properties.
