摘要(中):
近年來國內以打造永續台灣與綠建築為未來努力的方向,為解決雨水資源流失、環境生態破壞及熱島效應擴張,研發本土透水混凝土實有其重要性,透水混凝土鋪面可以使空氣與水自由地有效的滲入,地下土壤可保持濕潤,雨水也能夠快速滲入地面至地下水,地下水資源或水位能即時更新,它改善道路鋪面的環境,其它的優點尚包括具有良好排水、噪音吸附與車輛抗滑能力,適合舖設於台灣多雨多濕之環境,由於透水混凝土孔隙率較高,其強度低於一般混凝土,應用於重交通量公路面層因此受到侷限。本研究採用水泥、矽灰、強塑劑、鋼纖維、粗骨材等材料組成透水混凝土配比,期研發符合國內重交通量剛性路面的使用,試驗結果包括透水混凝土抗壓強度、抗彎強度、孔隙率、單位重與透水試驗說明如下:
模擬現地試驗塊其一之28天鑽心試體抗壓強度為275.7 kgf/cm2達一般結構物混凝土規定抗壓強度175 kgf/cm2 以上;其28天鑽心試體抗彎強度為48.11 kgf/cm2亦達高速公路剛性路面面層混凝土設計抗彎強度45 kg/cm2 以上之要求;四種不同透水混凝土試體之單位重介於1890至2034 kg/m3間與孔隙率範圍約為18.82%至31.87%之間高低相互呼應;有關模擬現地施作透水混凝土透水性良好,其現場透水量平均約為1100ml/15sec;希望藉由透水混凝土之研究成果,能提供工程界規劃設計與施工之參考。
摘要(英):
In recent years, the forever-lasting Taiwan and green architecture have become a major topic in our country. 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.
