porous concrete

基本解釋

According to this, the paper puts forward a kind of new permeable base material, which is called porous concrete.
對此，本文研究一種新型的多孔混凝土排水基層材料。
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縮現(xiàn)象，為研究多孔混凝土基層路面的接縫設置及反射裂縫問題，必須首先研究多孔混凝土的收縮特性。
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，在雨天可以通過其連通的孔隙將雨水回流到地下，因此常作為人行道面的鋪裝材料。

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.
并與傳統(tǒng)的半剛性和剛性基層作為對比,對多孔混凝土的強度和應力—應變、干燥收縮等性質進行了研究。
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.
在滿足強度要求的配合比的基礎上，設計三個目標孔隙率，研究透水混凝土孔隙率、水灰比、強度和透水性能之間的關系。
