| 中文摘要: |
| 在保证各标号混凝土配比和原材料不变的基础上，依次改变河砂含泥量（0%、2.0%、4.0%、6.0%），进行河砂不同含泥量对混凝土工作性能、外加剂掺量、坍落度损失以及抗压强度影响的试验研究，并对相应机理做出简要分析。试验表明，混凝土的扩展度、抗压强度均随含泥量的增加而减小，混凝土的外加剂掺量、坍落度损失随着含泥量的增加而增加。 |
| 英文摘要: |
| Given a fixed concrete mixture ratio, with the same raw materials, changing the mud rate in river sand at 0%、2.0%、4.0% and 6.0%, studied the influence of sand mud rate on the performance, admixture ratio, slump loss and compressive strength of concrete, and analysed in brief the Mechanism. The experiment shows that with the increase of mud rate, the expansion rate and compressive strength of concrete decreased, however， the mixture rate and slump loss increased. |
