本欧洲标准规定了确定新拌混凝土一致性的方法 坍落度测试。 坍落度测试对混凝土的一致性变化敏感，这对应于坍落度 在10mm和210mm之间。除了这些极端之外，坍落度的测量可能是不合适的 应考虑确定一致性的其他方法。 如果在取出锥体后1分钟内坍落度继续变化，则坍落度试验为 不适合作为一致性的度量。 当实际使用聚集的最粗略部分的D的声明值时，该测试是不合适的 在混凝土中（Dmax）大于40mm

This document specifies a method for determining the consistence of fresh concrete by the slump test. The slump test is sensitive to changes in the consistence of concrete, which correspond to slumps between 10 mm and 210 mm. Beyond these extremes the measurement of slump can be unsuitable and other methods of determining the consistency should be considered. If the slump continues to change over a period of 1 min after withdrawing of the cone, the slump test is not suitable as a measure of consistence. The test is not suitable when the declared value of D of the coarsest fraction of aggregates actually used in the concrete (Dmax) is greater than 40 mm.
