Magnetite nanoparticles, consisting of iron oxide (Fe 3O 4), are increasingly recognized for their potential to enhance the mechanical properties and durability of cementitious materials. These nanoparticles are particularly valued for their magnetic properties, high density, and ability to interact with cement at the molecular level. When incorporated into cement and concrete, magnetite nanoparticles can lead to improved compressive strength, enhanced durability, and increased resistance to environmental stresses. This makes them an attractive additive in the construction of infrastructures exposed to harsh environmental conditions such as high humidity, saline atmospheres, and fluctuating temperatures.
