摘要
介绍了混凝土防渗墙的研究现状,结合东平湖围坝塑性混凝土防渗加固,进行了混凝土原材料和配合比试验,结果表明:塑性混凝土的强度和弹性模量随水泥用量的增加而增大,随膨润土用量的增加而降低,弹性模量没有随砂率的提高而有效降低。认为对聚合物改性水泥基塑性混凝土的研究将会成为今后混凝土材料研究的主要方向。
The paper introduces the present status of study on concrete cutoff wall and conducts tests on concrete raw material and mixing ratio combining with the plastic concrete consolidation project of Dongping Lake diaphragm wall.The outcomes show that the intensity and elastic modulus of plastic concrete are increased along with the increase of cement consumption,decreased with the increase of bentonite consumption and the elastic modulus dose not effectively reduce along with the increase of sand ratio.It deems that the study on plastic concrete of polymers improved cement-based will be the main orientation of study on concrete materials in the future.
