Beyond these extremes the measurement of slump can be unsuitable and othermethods of determining the consistency should be considered.If the slump continues to change over a period of 1 min after de-moulding, the slump test is not suitable as ameasure of consistence.The test is not suitable when the maximum size of aggregate in the concrete is greater than 40 mm.【中国标准分类号】: Q13【国际标准分类号】: 91_100_30【页数】: 12P.;A4【正文语种】: 英语
