|Title:||The Influence of Near Surface Moisture and Specimen Thickness on Concrete Protection Treatment|
|Abstract:||Moisture content at the time of applying the protective material to concrete has the major influence on the success 3 or failure of the treatment process. The code of practice, BD 43/03 and BS EN 1504-2, suggests a maximum 4 moisture content of approximately 5.0% at the time of applying the treatment. However, this moisture content is 5 the bulk moisture content which is not representative for the ‘near surface’ moisture content. A new idiom is 6 presented in this study that represents the theoretical moisture content at the time of application. “Apparent 7 moisture content” is the water present near the surface of concrete and has the major effect on the application of 8 protective materials. In the second part of this research, the efficacy of two hydrophobic materials were tested in 9 terms of water absorption protection. Also, results from the Scanning Electron Microscope (SEM) for the 10 formation and distribution of the applied protective materials has been presented in this research.|
