摘要
进行了弯曲荷载作用下的水工钢筋混凝土梁的碳化加速腐蚀试验,在分析纯弯段混凝土碳化深度规律的基础上,研究了弯曲荷载对混凝土梁碳化耐久性寿命的影响。研究的结论表明,荷载作用将加速受拉区混凝土的碳化,并缩短梁的耐久性寿命。
A series of rapid erosion tests of carbonation for hydraulic RC beams with flexural loads are carried out.Based on an analysis of carbonation depths of concrete in pure bending block,the influence of flexural loads on carbonation durability life of hydraulic beams is studied.The analytical results show that loads will accelerate carbonation of concrete in tensile region and shorten durability of RC beams.
