透水混凝土透過空隙以便於地表水的排出，降低路面積水。本研究分析不同混凝體配比之抗壓強度與透水率試驗。首先，設計不同水泥、碎石比例混凝土，其次加入增塑劑以增加混凝土膠結力，並經過標準養護程序之後，量測其透水率和良好的抗壓強度。結果發現水泥含量約高，透水率越低、抗壓強度越高。 Permeable concrete passes through the porosity to discharge the surface water and reduce the road area water. This study analyzed the compressive strength and water permeability of different concrete ratios. First, concrete with various cement and gravel proportion were designed, followed by plasticizer to increase concrete cementing strength. After standard maintenance procedures, water permeability and compressive strength were examined. Outcomes shows that a high cement content will reduce the water permeability and increase the compressive strength.
