德意志民主共和国使用美国最近研究的从褐煤中提炼的褐色蜡,可以完全解决混凝土结构中钢筋的锈蚀问题。钢筋锈蚀是一个极其复杂的课题,同时也影响着混凝土结构的成本。钢筋锈蚀是由于氯盐与水渗入混凝土内部所致,氯盐与水渗入钢筋表面时,钢筋即产生氯化锈蚀,导致了混凝土本身的裂纹和剥落,这种作用的长期影响可以危及到
The use of the brown wax from lignite recently studied by the United States in the Democratic Republic of Germany can completely solve the problem of steel corrosion in concrete structures. Steel corrosion is an extremely complex issue, but also affects the cost of concrete structures. Corrosion of steel is caused by the infiltration of chloride salts and water into the interior of the concrete. When chloride salts and water infiltrate the surface of the steel bar, corrosion of the steel occurs, resulting in cracks and spalling of the concrete itself. This long-term effect of the action can be jeopardized
