Properties of NdFeB magnetic cement - ScienceDirect

Enhanced functional properties of cement pastes were achieved by introducing hard magnetic powders (NdFeB) into cement mixtures. The magnetic cement (cementitious magnet) employed a simple and inexpensive cementitious process to form complex NdFeB magnet shapes. NdFeB particles were distributed uniformly in the cement matrix.
