期刊Influence of surface impregnation with silane on penetration of chloride into cracked concrete and on corrosion of steel reinforcement
《International Journal of Modelling, Identification and Control》Wittmann, Folker H.[1,2]; Zhao, Tie-Jun[2]; Ren, Zhao-Jun[2]; Guo, Ping-Gong[3]
Capillary suction is suppressed by surface impregnation with silane. As a result, ingress of liquid water and harmful ions such as chlorides or sulphates dissolved in water is prevented. In practice, concrete structur...显示全部
