WebHydrophobicity is a key index to evaluate impermeability, corrosion resistance and durability of cement-based materials [1–6]. Hydrophobicity improvement of cement-based materials is e ective to improve their corrosion resistance and durability via the decrease of their permeability, which deserves extensive attention [7–11]. Amongst the many benefits of using hydrophobic concrete, it reduces installation time and lowers costs. Use of hydrophobic concrete can reduce the labor time of industrial project because normal concrete involves a corrosion proofing period as well as a waterproofing period. With hydrophobic concrete, both corrosion proofing and waterproofing are done at the same time. Likewise, time reduction reduces installation costs. Regular, membrane-backed concrete can co…
