| Abstract: | Considering the seriousness of river sand resources shortage, this paper analyzes the necessity and feasibility of sea sand resourcialization. On the findings of study on utilization of sea sand in foreign countries, limitative chloride content of the sea sand, sea sand desalination techniques and the durability of sea sand concrete, methods on maintenance and improvement for durability of sea sand concrete are discussed. A measure of surface-applied migrating corrosion inhibitors on hardened concrete is proposed,and sea sand utilization and dura- bility improvement of sea sand concrete may be achievable. At last, a suggestion of how to solve the key issues in the process of resourcialization of sea sand in China is put forward. |
