强度和耐久性是混凝土结构的两个重要指标。随着我国建筑结构物老化和环境污染的加重,科学、合理、优质地设计、提高混凝土耐久性及防腐性,延长建筑物结构的使用寿命,已成为房建单位各主管部门和广大设计、施工部门关注的焦点。本文提出了控制好原材料的性能,合理调整使用,加强养护,开展耐久性试验等措施。结果证明,工程应用良好,混凝土抗氯离子、抗碳化、抗硫酸盐等性能均满足设计和国家标准要求。
Strength and durability are two important indicators of concrete structure. As China’s building structure aging and environmental pollution aggravate, scientifically, reasonably and finely designed to improve the durability and corrosion resistance of concrete to extend the service life of the structure of the building has become the competent departments of the construction unit and the majority of design and construction Department focus. This paper puts forward some measures such as controlling the performance of raw materials, adjusting the use rationally, strengthening the conservation and testing the durability. The results show that the engineering application is good, concrete resistance to chloride ions, anti-carbonation, anti-sulfate and other properties to meet the design and national standards.
