英文摘要：

Carbon nanofibers （CNFs） have become hotspots in recent years in the nanomaterials＇ fields. The characteristics, performances and applications of CNFs and cement-based materials are introduced individually. Fur thermore,the possibility of cement base reinforced by CNFs is analyzed systematically. It is concluded that the key of the problem are the homo-dispersion of CNFs in the cement-based materials and the compatibility between CNFs and the matrix. The scheme for solving the problems is put forward. It lays the foundation for the following engineering application and research.
