摘要
用周期浸泡加速腐蚀试验法研究ｐＨ＝３．５、５．６和ｐＨ为１．０时ＳＯ２－为０、０．０６、０．１、０．２ｍｏｌ／Ｌ等６种模拟酸雨条件下混凝土、砂浆和灰砂砖的化学行为。研究表明：酸雨对材料的影响，主要是Ｈ＋侵蚀引起的溶解腐蚀和ＳＯ４２－侵蚀引起的膨胀腐蚀。
The chemical behaviors of concrete,sand-lime slurry and sand-lime brick were studied by using the periodical immersion corrosion accelerating methods under the condition of simulated acid rain of different acidity and SO_4￣2 concentration. The results showed that the main cause of erosion of sand-lime slurry by acid rain was dissolving erosion by H￣+ and expanding erosion by SO_4￣2 .
