    摘要: Cast iron pipe and other elongated hollow articles are lined with a cementitious mortar for certain applications, such as the transmission of potable water or sewage. To improve the resistance to attack from acids and to provide a crack and void spot free cement lining, a calcium alumina cement is used to line the article. A plasticizer such as fireclay is added to the calcium alumina cement prior to its application. The cement lined article is then coated with an asphaltic based coating and then cured in a high humidity environment.
