Abstract

The invention relates to an application of graphene oxide as a reinforcing agent of a cement early strength, and belongs to the field of building materials. The invention provides the application of graphene oxide as the reinforcing agent of the cement early strength. Graphene oxide is nanoscale high polymer material, and not only can fill small gaps among cement particles, so that a microstructure of the cement is dense and flat, and also graphene oxide has high surface activity, so that a hydration process of the cement can be promoted, and the mechanical property of the cement is effectively improved.

Description

technical field [0001] The invention relates to the application of graphene oxide as an early strength enhancer of cement, belonging to the field of building materials. Background technique [0002] Cement-based materials are widely used in infrastructure such as houses, bridges, and coastal dams. However, with the development of economic construction, higher requirements are placed on the performance of cement-based materials; The erosion of harmful substances will inevitably lead to the degradation of the performance of cement-based materials, resulting in initial damage to the structure, which directly affects the durability of the structure. How to improve the early performance (mechanical properties, durability) of cement-based materials is of great significance to improve the durability of concrete structures, and related research has gradually attracted the attention of civil engineering circles at home and abroad. [0003] Graphene oxide has very excellent propertie...
