Influence of nanoparticles on mechanical and nondestructive properties of high-performance concrete

This article aims to investigate the influence of nanoparticles on mechanical and nondestructive properties of high-performance concrete (HPC). For this purpose, nano-SiO2 (NS), which chemically prepared as well nanofly ash (NFA), nanosilica fume (NSF) and nanocoal (NC), prepared by mechanical grinding, have been added to concrete mixtures. NS was added in four percentages (1, 2, 3 and 4%) of weight of cementitious materials whereas NFA, NS and...
