Abstract EN
Water repellent treatment has been considered an effective preventive method against water and aggressive ions penetration into concrete and consequently can improve the durability of concrete structures.
In reality, many concrete structures are exposed to conditions with high risk of carbonation.
In this contribution, one type of ordinary concrete had been prepared and surface impregnated by 400 g/m2 silane cream and 100 g/m2 and 400 g/m2 silane gel.
In addition, integral water repellent concrete was produced by adding 2% silane emulsion.
Then, the specimens were exposed to accelerated carbonation for 7, 28, and 72 days.
The effect of water repellent treatment on carbonation of concrete has been investigated.
The results indicate that surface impregnation reduced carbonation depth of concrete under RH 70%, but integral water repellent concrete increased carbonation.
Carbonation reaction started behind the hydrophobic layer in the surface-impregnated concrete.
The coefficient of carbonation can be described better by a hyperbolic function of time.
Treatment by 400 g/m2 silane gel and silane cream showed better efficiency on reducing carbonation than usage of 100 g/m2.
Coefficient of water capillary suction was decreased significantly by both surface impregnation and integral water repellent treatment.
It is an effective method to protect concrete from water penetration into the material.
