摘要 含泥量是衡量混凝土用粗、细骨料质量的一项重要指标,粗、细骨料含泥量超标会直接影响混凝土拌合物性能和混凝土强度.本文结合水工混凝土用粗、细骨料实际应用情况,对比常用标准在粗、细骨料含泥量指标规定的差异,针对施工现场中常出现的超标现象,采用试验对比提出将粗、细骨料含泥量叠加的观点,对今后工程实际遇到类似问题采取相应有效措施具有一定的帮助. Silt content is an important indicator for measuring the quality of concrete coarse and fine aggregates, if exceeding the standard limits, it will directly affect the performance of concrete mixture and concrete strength. This paper takes the actual application of coarse and fine aggregates into consideration and compares the differences of general standards in the regulation for silt content in both aggregates. In specification to that the silt content in coarse/fine aggregate in construction site can exceeds the limits, through test comparisons it' s proposed to add the values together. The paper can be of certain help to similar problems in future projects.
