| 摘 要： | 按C50预制混凝土桥梁的现场配合比设计要求,通过实验室模拟酸雨条件下桥梁混凝土的耐酸雨侵蚀性能,根据模拟酸雨中5种混凝土的抗折、抗压强度的变化与模拟结束时对比样品的试验结果分析可知:掺加矿渣、SBR聚合物和粉煤灰对混凝土后期力学性能有一定改善作用,或降低酸雨对混凝土侵蚀程度和速率.

| Abstract: | According to the design requirements of the local C50 pre-cast bridge concrete,through the experiment investigation on corrosion of simulated acid rain to bridge concrete,the influence of simulated acid rain on the properties of concrete is studied by measuring the index of the flexural strength and compressive strength.Based on the research,the concrete resisting acid rain was applied in civil engineering,adding slag,SBR polymer concrete and fly ash on concrete improved the mechanical properties of the lat... |
