Coefficient of permeability and pore volume of coated mortar were obviously less than those of non-coated one. Effect of siliceous coating reached the inside 5 to 10mm of coated morta.
Reduction of pore volume was caused by the decrease of capillary pores within the size range 0.1 to 1/μm. Relationship of them can be described by the equation y=3.25×10?x??, where y is coefficient of permeability and x is pore volume.
