Evaluation of Colloidal Nanosilica Diffusion for the Recovery of Aged Cementitious Matrices in Hydraulic Structures: Insights from Thermogravimetric Analysis

This study demonstrates that a colloidal nanosilica-based repair product (Elera) effectively restores the calcium silicate hydrate matrix in highly porous aged concrete from hydraulic structures through pozzolanic reactions, though its efficacy is limited in lower-porosity samples, highlighting the need for alternative application methods like injection.

Corrosion Initiation and Propagation of High-Strength Steel for Marine Engineering in 3.5 wt.% NaCl Solution

This study demonstrates that Ni8CrMoV high-strength steel exhibits superior corrosion resistance compared to Ni2CrMo steel in marine environments due to its higher Ni and Mo contents, which promote the formation of a protective rust layer and isolated pitting, whereas the lower alloying content of Ni2CrMo leads to rapid pit coalescence and accelerated transition to uniform corrosion.
