超疏水混凝土的制备及应用于防腐防冰领域的研究进展.

Concrete is the most widely used building material in civil infrastructure in the world, but because its hydrophilic and porous surface structure promotes the penetration of water and the erosion of corrosive ions, the concrete is damaged by freezing and melt, expansion and denudation, which leads the safety and durability of concrete structure to seriously reducing. Superhydrophobic surfaces have good water resistance and can be applied to concrete, coating or overall superhydrophobic concrete has received considerable attention in the last decade, and also has a good application value in the field of anticorrosion and ice prevention. In this context, this paper first briefly summarizes the basic wettability model for concrete concrete cases. Secondly, we review the existing advanced strategies for constructing superhydrophobic concrete, mainly divided into surface hydrophobic modification and overall hydrophobic modification, and summarize the advantages and disadvantages of two different strategies. When the concrete is in the extreme environment such as cold and marine environment, it is particularly important to improve the anti-corrosion and ice prevention performance of the concrete, so the influence of the water modification is discussed in this paper. In addition, the theoretical basis of superhydrophobic modification technology for concrete corrosion and ice is briefly described. Finally, the challenges in the current fabrication and application of superhydrophobic concrete and the potential solutions to these problems are indicated. [ABSTRACT FROM AUTHOR]
