In order to resolve the runoff of rainwater resource, to prevent the spoliation of ecology and to reduce the effect of heat island, to search for the suitable mix design of the pervious concrete for Taiwan is not a small issue. Pervious concrete pavement is air permeable and water permeable, the soil underneath can be kept wet and rainwater can quickly filter into ground, so the groundwater resources can renew in time. It improves the environment of road pavement and also possesses many other advantages that improve city environment at drainage, sound absorption and skid resistance, and is suitable for the rainy and humid environment in Taiwan area. However, its high air voids results in low strength, the surface layer of highway pavement was seldom used pervious concrete due to heavy traffic loading. This study is to search the suitable mix of pervious concrete by using cement, silica fume, superplasticizer, steel fiber, course aggregate and so on for highway rigid pavement. The test results including compressive strength, flexural strength, unit weight, void content, and permeability test were described as follows: The compression strength of one pervious concrete core specimen from the simulated field site can be up to 275.7kgf/cm2 and exceeds the ordinary concrete structure specification (175 kgf/cm2). The flexural strength of one pervious concrete core specimen from the simulated field site can be up to 48.11kgf/cm2 and exceeds the highway rigid pavement specification (45 kgf/cm2). The void content can range from 18.82 to 31.87% with unit weights of 1890 to 2034 kg/cm3 during four mix of pervious concrete. The water penetration of the above pervious concrete is very good and the field permeability test for the simulated field site is about 1100ml/15sec. This study of pervious concrete will be valuable for design and construction of practice. Ming-Gin Lee 李明君 2008 學位論文 ; thesis 76 zh-TW |
