Hydrophobic/Superhydrophobic Concrete SpringerLink

Jun 13, 2017  Hydrophobic/superhydrophobic concrete is a kind of concrete, in whose surface the water is repelled through the hydrophobic/superhydrophobic treatment. The hydrophobicity/superhydrophobicity can be characterized by contact angles between the tangent line of droplets and solid surface.

Nano-engineered Superhydrophobic and

Another method to improve the durability of concrete is based on the addition of superhydrophobic admixtures of polymethyl hydrosiloxane emulsions and nano particles. These admixtures can produce a 3-dimensional volume hydrophobization by releasing hydrogen in alkali environments enabling the formation of air voids throughout a cementitious matrix.
