摘要

There are currently many types of protective materials for reinforced concrete structures and theinfluence of these materials in the chloride diffusion coefficient and water penetration still needs moreresearch. The aim of this work is to analyze the contributions regarding the typical three surfaceconcrete protection systems (coatings, linings and pore blockers) and discusses the results of three poreblockers (sodium silicate) tested in this work. To this end, certain tests were used: one involvingpermeability mechanism (low pressure-immersion absorption), one involving capillary waterabsorption, and the last, a migration test used to estimate the effective chloride diffusion coefficient insaturated condition. Results indicated reduction in chloride diffusion coefficients and capillary waterabsorption, therefore, restrictions to water penetration from external environmental. As a consequence,a reduction of the corrosion kinetics and a control of the chloride ingress are expected.
