摘要
无砂多孔混凝土（简称无砂混凝土）在水工建筑中作反滤孔，排水暗管和减压井管的过滤器等，其配合比设计及施工工艺与普通混凝土不同。本文对无砂混凝土的配合比设计、施工工艺和性能进行了试验研究，提出了无砂混凝土反滤排水管的最佳配合比。
Abstract No-fines concrete was uesed in hydraulic structure as filter pipe, drainage pipe and filter of well pipe. the disign of mix proportion and construction technique of no-fines concrete is different from the concrete's, this essay has researched the disign mix proportion, construction technique and performance of no-fines concrete, the mix proportion as filter drainage pipe is raised.
