Research

My Ph.D. program is entitled “Experimental study and numerical simulation of the transport properties and volume stability of lime mortars at micro-scale and meso-scale”. It is part of the Sublime (Sustainable building lime applications via circular economy and biomimetic approaches) initiative, and it proposes a framework for simulating physical/mechanical properties and a better understanding of the volume stability of lime mortars. My last study was about the improved autogenous mortar self-healing in the alkali-aggregate reaction.

Title: Experimental study and numerical simulation of the transport properties and volume stability of lime mortar at micro-scale and meso-scale (TU Delft)
Objective: Upscale the microstructural properties from paste level to meso-scale at mortar level; and study the physical and mechanical properties of lime-based mortar, i.e., water permeability, moisture and ion transport, creep and shrinkage.

Title: The self-healing effect of mortars on the alkali-aggregate reaction (Federal University of Paraná)
Objective: This study investigated the improved autogenous healing behavior of mortars submitted to the alkali-aggregate reaction. The mortar mixtures included a reactive aggregate (previously tested) and different contents of crystalline admixture and polypropylene microfibers. The crack-induction method included the immersion of the mortar bars in a sodium hydroxide solution.

Title: Crystalline admixture and polypropylene microfiber as internal sulfate attack mitigating agents (Federal University of Paraná)
Objective: This research evaluated the effect of crystalline admixture and polypropylene microfiber in the development of Internal Sulfate Attack (ISA) due to pyrite oxidation. An aggregate with a 10% content of pyrite was evaluated. The experimental program performed with eight mortar mixtures lasted for 168 days (24 weeks).

During my Master’s program, I had the chance to work actively on several research projects. Therefore, besides helping with the experimental activities, I also helped with writing, translating, editing, formatting, proofreading, and reviewing papers.
