porous concrete

基本解释

According to this, the paper puts forward a kind of new permeable base material, which is called porous concrete.
对此，本文研究一种新型的多孔混凝土排水基层材料。
Porous concrete will shrink, so it is necessary to deal with its shrinkage character firstly when studying the problems of joint location and reflection crack of porous concrete base.
由于多孔混凝土存在收缩现象，为研究多孔混凝土基层路面的接缝设置及反射裂缝问题，必须首先研究多孔混凝土的收缩特性。
As porous concrete has a good performance of permeability in the rainy day, which can put the water back to the underground through its connectivity, so it often be used to the sidewalks.
由于透水混凝土具有良好的透水性能，在雨天可以通过其连通的孔隙将雨水回流到地下，因此常作为人行道面的铺装材料。

Oxman estimates that making concrete columns this way—with low-density porous concrete in the center—could reduce the amount of concrete needed by more than 10 percent, a significant savings on the scale of a construction project.

Replacing concrete with porous pavement, employing green roofs and rain barrels, restoring creeks and wetlands, and increasing tree cover can help cities absorb rain water rather than funnel it to sewer systems.

多孔混凝土
The strength,stress-strain and dry shrinkage of porous concrete are investigated.
并与传统的半刚性和刚性基层作为对比,对多孔混凝土的强度和应力—应变、干燥收缩等性质进行了研究。
透水混凝土
Then holerate of porous concrete is measured in situation of different water-cement ratio toresearch penetrative ability affected by hole ratio. The three target hole rate is designed when strength is met.
在满足强度要求的配合比的基础上，设计三个目标孔隙率，研究透水混凝土孔隙率、水灰比、强度和透水性能之间的关系。

多孔混凝土
The results can provide a reference for the mix design of porous concrete.
研究结果可为无砂多孔混凝土的配合比设计提供参考。
透水混凝土
The porous concrete is a kind of environmentally-friendly concretewith continuous porosity mixed with special technology. It has certainintensity and permeability of air and water.
透水混凝土是一种生态环保混凝土，是经过特殊工艺制成的具有连续孔隙的混凝土，既有一定的强度，又有一定的透气透水性。
