Effect of Inorganic Surface Treatment on Air Permeability of Cement-Based Materials

Permeability 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...
