引用本文摘 要：利用自制透水系數測試裝置測試透水混凝土的透水性能，主要研究了成型工藝、設計孔隙率、石子粒徑、砂率對透水混凝土透水性能的影響。結果表明，自制透水系數測試裝置可以較準確地測試透水混凝土的透水性能，各種成型工藝下制備的透水混凝土具有不同的透水系數。砂率越大，透水系數越??；石子粒徑越大，透水系數越大；透水混凝土的孔隙率越大，透水系數越大；有效孔隙率與透水系數之間存在一定的線性關系。 Abstract: Permeability performance of the pervious concrete is tested by self-made testing device, and the effects of the molding process, design of porosity, particle size of gravel and sand ratio on the permeability performance of pervious concrete are studied. The results show that permeability performance of pervious concrete can be more accurate tested by self-made testing device, and the pervious concrete has different permeability coefficient which is prepared with different molding processes. The permeability coefficient is smaller with the greater sand ratio. The permeability coefficient is greater with the greater gravel particle size. The greater of the porosity of the pervious concrete, the greater of the permeability coefficient. And there is a linear relationship between the effective porosity ratio and permeability coefficient.
