A Review on Properties of Concrete with Magnetizing Cement

Abstract

The incorporation of strong magnetic powders (NdFeB) into cement mixtures has produced improved mechanical properties of cement pastes. The magnetic cement (cementitious magnet) used a simple and inexpensive cement process to form complex forms of the NdFeB magnet. Particulate NdFeB has been distributed uniformly in the cement matrix. The magnetic cement composites increased in density and compressive strength with the NdFeB concentration. Magnetization (stable up to one year) also increased with NdFeB powder but there was no improvement in coercivity. The introduction of magnetic particles into cement matrices has also been another important method in recent years to enhance the mechanical and other properties of cement-based materials. Nanoparticles (IONs) made from iron oxide (Fe 2 O 3 , Fe 2 O 4 ) are among the most popular cement fillers. Cement composites mixed with IONs showed enhanced compressive strength, as well as other enhanced functions. This paper presents literature analysis of a study of magnetizing cement on concrete properties.
