原子力显微镜PeakForce QNM模式下纳米碳材料改性水泥基材料微区力学性能研究

The research on the performance of cement-based materials at multi-scale is a hot issue in recent years. Based on the PeakForce QNM analysis and testing methods and computer technology, this subject chooses nano-carbon material reinforced cement-based materials as the basic research object, discusses the basic theory and basic method of PeakForce QNM test, analyzes the cement-based material pastes and its interface Micro-morphology and mechanical properties, the establishment of visual, continuous microstructure evaluation system. The macroscopic mechanical properties and the mechanical properties of the micro - nanostructure are combined to analyze the mechanism of the enhancement of the nano-carbon materials, which provides a solid theoretical basis for the further modification of the material and the development and design of the new material.
