虽然水泥砂浆衬砌已被广泛采用，并已成功地防止电化学腐蚀效应，但最近的研究表明，衬砌本身可能无法抵抗腐蚀。从这个意义上说，“腐蚀”是指石灰从砂浆中渗出，导致钙流失，并可能导致衬砌结构劣化。此外，浸出的石灰可能会增加pH值、碱度和钙浓度，从而影响水质。本项目旨在研究水泥砂浆衬砌腐蚀的原因和影响。主要目标是:调查美国腐蚀问题的严重程度；识别导致腐蚀的因素；检查各种水质参数和水泥成分对水泥的影响- 砂浆腐蚀；并建议公用事业公司可以采取的措施，以尽量减少腐蚀问题。该报告主要关注现场（就地）管道衬里，因为标准密封涂层和工厂衬里管道只注意到了一些问题。然而，也讨论了工厂内衬和密封涂层管道。本文介绍了该项目。它介绍了水泥砂浆衬里腐蚀的背景，然后描述了美国公用事业公司的调查，以了解衬里腐蚀的行业经验。本文讨论了现场试验，以调查衬里腐蚀的原因和控制，随后从水质影响和衬里影响方面检查了结果。最后是结论和建议。

While cement-mortar lining is widely practiced and has been successful in protecting against electrochemical corrosive effects, recent research indicates that the lining itself may not be immune to corrosion. "Corrosion," in this sense, means the leaching of lime from the mortar, causing calcium loss and possibly leading to structural deterioration of the lining. In addition, leached lime may impair water quality by increasing the pH, alkalinity, and calcium concentrations. The purpose of this project was to study the causes and effects of cement-mortar lining corrosion. Principal objectives were to: investigate the extent of the corrosion problem in the United States; identify factors leading to corrosion; examine the effects of various water quality parameters and cement compositions on cement-mortar corrosion; and recommend measures a utility can implement to minimize corrosion problems. The report focuses on in situ (in place) pipe lining, because only a few problems have been noticed with standard seal-coated and factory-lined pipe. However, factory-lined and seal-coated pipe are also discussed. This paper describes the project. It presents background on cement-mortar lining corrosion, then describes a survey of US utilities to learn about industry experience with lining corrosion. The paper discusses field tests to investigate the causes and control of lining corrosion, and follows with an examination of results in terms of water quality effects and lining effects. It closes with conclusions and recommendations.
