Improvement Of The Durability Of Concrete Based On Surface Treatment Technology

The application of concrete has been a hundred years of history,is the world's most widely used building materials.The design life of the building and the durability of the building(building life)are two different concepts.In the ideological understanding of people there is a common misunderstanding,that is: all the concrete is durable.Concrete technical standards and specifications of the durability of concrete only mention and there are no clear implementation measures and regulations,which is leading to the general durability of concrete is one of the main reasons.The project——Using Surface Treatment Technology to Improve the Durability of Concrete has been done by Water Resources Research Institute of Jilin is taken in this paper.Based on the analysis of the causes of concrete structure failure,the mechanism of surface treatment to improve the durability of concrete,the study of surface treatment and cement concrete compatibility,the development of surface treatment materials and the effect of surface treatment materials on the freeze-thaw effect of concrete are more comprehensive Research.It can be seen that the use of surface treatment technology has practical significance for the expansion,transformation,maintenance and landscaping of existing concrete projects through the practical application of the concrete instance of the arch dam of the Qingshan Lake Reservoir.The subject of the existing concrete surface treatment with minimal investment produce the least amount of construction waste,to achieve a substantial increase in both the service life of concrete engineering.And,more importantly,through the concrete base material surface processing,the existing concrete activity itself better preserved,the existing concrete structure internal maintain "health",make the durability of existing concrete structure with real.
