风加速Ⅱ型混凝土梁碳化试验研究

已有工程检测、理论分析和试验研究表明，风对混凝土碳化的加速作用是客观存在的，进而导致混凝土构件截面耐久性不等。铁路公路桥梁等混凝土保护层直接外露的结构，其碳化受风影响的程度更为明显，研究不同形状桥梁梁体的不同部位混凝土受风影响的碳化情况具有较大的现实意义。本文进行了风加速Ⅱ型混凝土梁的碳化试验，对试验结果进行了分析总结，并采用试验数据对理论模型的计算结果进行了检验。考虑风对混凝土碳化的加速作用对混凝土结构的等耐久性设计具有重要意义。

Testing Study on II Type Beam Concrete Carbonisation Accelerated by Wind

Concrete carbonisation can be accelerated by wind, which makes the durability of the section of concrete structure different everywhere. It has been testified by the present theories and researches. The protection cover of the railway and road bridge concrete beam usually exposure in atmosphere environment, and the phenomenon of concrete carbonisation influenced by wind is more obvious, so it is significant to research the bridge beam carbonisation influenced by wind. The experiments of II type concrete bear carbonisation accelerated by wind pressure have been performed, and this paper used the experiment data to validate the calculate results. Thinking the influence of wind pressure is important for equal durability design of the section of concrete structure.
