Nowadays, the application of nanotechnology has gained increased attention in the concrete technology field. Several applications of concrete require light weight; one such concrete used is foamed concrete (FC), which has more voids in the microstructure. In this study, silicone-dioxide nanoparticles (SDN) is used, which exhibits a pozzolanic nature, and it reacts with other pozzolanic compositions to form hydrated compounds in the concrete.
