Mechanical Properties of Cement Mortars Incorporating Zero-Valent Iron Nanoparticles
In this study, the effects of zero-valent iron (ZVI) nanoparticles (NPs) on the mechanical performance of cementitious composites were investigated. For this purpose, the use of a novel nanomaterial containing ZVI NPs blended with carboxymethyl cellulose (CMC) and was introduced. NPs were prepared by a green and low-cost sonochemical method at room temperature and characterized using scanning electron microscopy/energy dispersive X-ray spectroscopy, thermal gravimetry analysis, Brunauer–Emmett–Teller, and X-ray diffraction techniques. The values of intrinsic viscosities of NPs were examined to determine the optimal miscible condition as affected by the different mass ratios of and sonication time. Then, eight different cement mortar specimens containing and NPs were prepared in ratios of 0.2%, 0.5%, 1%, and 2% by weight, and flexural and compressive strengths of the specimens were determined at the ages of 7 and 28 days. The microstructure of the specimens was also evaluated. Comprehensive results proving the improvement in the mechanical properties have been obtained in the specimens containing 1% and 2% NPs.
