Mitigating External Corrosion of Pipelines Through Nano-Modified Cement-Based Coatings

This project consists of three main tasks. The first task will be to develop an effective processing technique to produce the cement-based coating, namely effective dispersion of the nanomaterials. This will be approached through physical and chemical methods: sonication and surfactant treatment, respectively. The second task will be to characterize key rheological properties of the coating material: thixotropic structural rebuilding and fresh-state adhesive properties. This will be done through a shear rheological "breakdown-recovery" protocol and the tack test, respectively. The last task will be to characterize key hardened properties: porosity and crack resistance under fatigue and restrained shrinkage. This will be done through monitoring weight loss, flexural testing under cyclic loading, and the ring test, respectively.
