    Abstract: This disclosure teaches a system for placing structurally an inorganic alkaline sealant (such as portland cement) by dispersing the alkaline sealant in a polyurethane foam material. The foam material may be cast and fabricated into bands, gaskets, joint packings and other structural elements which are placed in locations such as joints, cracks or the like where they are needed for sealing or protective functions. The alkaline sealant forms a rocklike mass when exposed to water and also releases alkalinity so as to protect adjacent metal surfaces. Gradual release of the alkalinity sustains protection of the metal surfaces for an extremely long time.

    Abstract translation: 本公开教导了通过将碱性密封剂分散在聚氨酯泡沫材料中来结构地放置无机碱性密封剂(例如波特兰水泥)的系统。 泡沫材料可以铸造和制造成带,垫圈,接缝填料和其它结构元件,这些结构元件放置在诸如关节,裂缝等的位置,在那里它们需要密封或保护功能。 当暴露于水中时,碱性密封剂形成岩质,并释放碱度,以保护相邻的金属表面。 碱度的逐渐释放可以保持金属表面的长时间保护。
