Study on the application of graphene in cement matrix composites

Abstract

In the rapid development of information technology, communication electronic equipment as one of the indispensable tools for people's life and work, although the transformation of the traditional communication technology mode, but also produced a lot of electromagnetic wave pollution. From the perspective of the normal living and working environment of human beings, mass electromagnetic wave pollution will not only cause harm to human life and health, but also threaten the application quality of electronic equipment and data information. In this paper, on the basis of understanding the structural characteristics and application status of graphene, the cement based composites were experimentally analyzed by using graphene oxide (GO), nano-Fe3O4 and reduced graphene-Fe3O4 hybrid material (RGO-Fe3O4), and the effects of the types and output of nanomaterials on the electromagnetic shielding performance and hydration process composition were mainly discussed. The final experimental results show that when the doping amount of RGO-Fe3O4 reaches 0.05%, the electromagnetic shielding efficiency of cement pattern can reach the highest. Among them, GO acts as a template for cement hydration process, and the early hydration has the most significant effect.
