浅谈粘土掺入量对混凝土防渗墙性能的影响

Discussion on Influence of Mixing Amount of Clay on Performance of Concrete Seepage Prevention Wall

防渗墙混凝土要求混凝土具有弹性模量低、变形性能好，能有效适应土坝坝体的变形。经过粘土混凝土配合比综合试验及粘土混凝土性能测试，水胶比、土掺量是影响混凝土性能的主要因素。经水库施工应用，所建大坝防渗墙混凝土满足设计指标，质量合格。

The seepage prevention wall concrete requires that the concrete has the low elastic modulus, good deformation, and can effectively adapt to the deformation of earth dam body. Through the clay concrete mixing proportion integrated test and clay concrete performance test, water-to-binder ratio, earth mixing amount are the main factors that affect the concrete performance. Through the construction application of reservoir, the built dam seepage prevention wall concrete meets the design index and qualifies the quality.
