摘　　要：含泥量是反映砂子生产技术水平的一个重要指标，对灌浆料的的工作性以及硬化后混凝土的力学性能和耐久性能都有影响。试验结果表明，随含泥量的增加，混凝土的工作性明显下降，尤其是当含泥量大于4．4％时下降更明显；含泥量增加灌浆料的力学性能下降、收缩增大。本文的研究为今后灌浆料的研究提供了可靠的技术参考。The clay content is an important indicator to reflect the level of production technology of sand. It has impact on the workability of grouting material and the mechanical properties and durability of haddening concrete. The test results show that increasing with the clay content, workability of concrete decreases obviously, especially when the clay content is more than 4.4% it decline more obvious. When the clay eontent increase the mechanical properties of grouting material decline, and the shrinkage increase. The studies of this paper provide reliable teehnieal reference for grouting material in the future.
