本文用化学侵蚀法研究了CsB3O5晶体的潮解取向,并从晶体结构上给予了解释:由于CsB3O5晶体的B-O骨架在(010)方向存在较大的通道,水分子较易沿(010)方向进入晶体而导致晶体潮解。
5) chemical corrosion
化学侵蚀
1.
Therefore,the chemical corrosion and sensitivity of underground reinforced concrete storeroom in these regions is analyzed and discussed in this paper according to the physical and chemical characters of collapsible loess,and the corresponding precaution measures are brought forwa.
由于湿陷性黄土的特殊性,致使在这些地区建设的地下钢筋混凝土贮库出现了不同程度的损伤,影响了结构的正常使用和安全性,为此,根据湿黄土的物理和化学特性,对在这些地区兴建的地下钢筋混凝土贮库的湿陷敏感性和化学侵蚀问题进行了分析探讨,根据产生敏感性的原因和化学成份———碳酸盐和硫酸盐对混凝土的侵蚀机理,提出了相应的防范措施,从而提高了湿陷性黄土地区地下钢筋混凝土贮库的使用年限和安全性,对指导工程建设具有重要的意义。

化学侵蚀
1.
Effect of mineral admixtures on resistance to chemical attack of blended mortar;
矿物掺合料对高强砂浆抗化学侵蚀性能的影响
2.
Furthermore,compared to the deicer-frost scaling,the chemical attack of these salts on concrete is quite weak.
研究了8种包括无机和有机化学物质的盐和融雪剂对混凝土盐冻破坏和化学侵蚀的影响,结果表明:只要是能除冰雪的化学物质,不论其化学组成,均会引起混凝土严重的盐冻剥蚀破坏,不存在所谓的对混凝土无害的除冰盐或融雪剂,因此,只要撒除冰盐或融雪剂,就必须对混凝土采取防治盐冻破坏的技术措施。
3.
Effects of salt crystallization of Na_2SO_4 and NaCl on concrete exposed to drying-wetting cycles were investigated by using index including concrete scaling amount,concrete expansion rate and strength loss rate,and chemical attack of concrete soaked in Na_2SO_4 and NaCl solutions was also measured.
以混凝土剥落量、膨胀率和强度损失率为评价指标,研究了干湿循环条件下Na2SO4和NaCl盐结晶对混凝土的破坏,并与在Na2SO4和NaCl盐溶液中浸泡的混凝土的化学侵蚀破坏结果进行对比。
