Hydrophobicity of the native surface after different preservative treatments is to evaluate the important indicator of surface antiseptic property.Concrete surface it is hydrophobic
Property is one of critical nature of concrete durability, and it is together decided on by the chemical composition and micro-geometry on surface.
When drop is dropped in concrete water flat surface, drop has a certain degree with concrete surface shape and reaches balance, and this is put down
Weighing apparatus angle is normally referred to as contact angle, and contact angle is represented with " θ ".θ size can weigh the infiltration degree of the surface of solids, θ
More big then concrete hydrophobicity is better, and its automatically cleaning or easy cleaned effect are better, while suppressing the energy of corrosion factor intrusion
Power is stronger.
