Effects of FeNi3/SiO2 /GO nanoparticles on the mechanical and durability properties of concrete

Abstract

Recent research in the construction industry supports the idea that nanomaterials can partially replace cement. A recently suggested material as a suitable substitute for cement in concrete is graphene oxide nanocomposite. As a result, in this laboratory study, FeNi3/SiO2/GO nanoparticles [NFSG] and SiO2 nanoparticles [NS] partially replace cement by 1, 2, and 3% by mass after their synthesis and confirmation by FT-IR, SEM and TEM analyses and their impact on the mechanical and durability characteristics of the specimens at ages 7, 28, and 90 days were examined. The findings imply that the designs with the highest mechanical properties tests produced the best results. These designs used 2% of NFSG and 2% of NS substituting cement. After 28 days, NFSG-containing concrete increased compressive strength by 15% and splitting tensile strength by 13%. FTIR spectra demonstrated that specimen containing 2% of NFSG produced more C-S-H [calcium silicate hydrate] gel, improving the microstructure of concrete and subsequently its properties.
