description abstractPermeability is an important indicator of durability of cement-based materials. Surface treatment is a simple method to reduce the permeability of cement-based materials. This paper evaluates the air permeability of cement-based materials treated with fluosilicate and sodium silicate. An air permeability test was utilized to measure permeability. The results revealed that both fluosilicate and sodium silicate could effectively reduce the air permeability of concrete. The benefits of magnesium fluosilicate treatment occurred mainly during the first 28 days. Sodium fluosilicate pretreatment made the waterglass treatment more effective in reducing the air permeability of concrete. The thermal analysis of free Ca(OH)2 in hardened cement paste found that the penetration depths of these inorganic surface-treatment agents were approximately 5 mm.
