Improvement in the physical and mechanical properties of the cement-based composite with the addition of nanostructured BN–Fe3O4 reinforcement

Abstract In this work, the performance of modified cement by nanostructures consisting of boron nitride (BN) and iron oxide inorganic nanoparticles (Fe3O4) was analyzed. The mechanical strength, electrical resistivity, and the degree of cement hydration as well as the microstructure were investigate...
