- Synopsis:
- The present study deals with the influence of surface coatings on the scaling of the concrete surface by the freezing and thawing action. The freezing and thawing tests were performed on concrete specimen some of which were treated with coating materials. For this purpose five different water repellents were used. The influence of the curing period of coating, the strength of concrete and the condition of concrete surface were studied. The obtained results show that the resistivity of concrete against the scaling increases when treated with water repellents. However the success of the concerning treatment can be optimized by the use of the adequate surface coating material.
