| 摘 要： | 对无砂透水混凝土的配合比与性能进行了试验研究，并将强度高、孔隙率大、透水性好的混凝土应用于北京市南北长街道路工程中，并对施工要点进行了论述。试验结果表明：对同一粒径的骨料拌制无砂混凝土，存在着最佳水泥用量和水灰比；对于不同粒径的骨料。在水泥用量相同时，并非骨料粒径小的混凝土强度大；无砂混凝土的渗透系数与连通孔隙率有较好的对应关系。

| Abstract: | It introduced the mix proportion and performance of no-fines pervious concrete,and the concrete which is of high strength,large porosity ratio and good water permeability was used in the Beijing North-South Long Street road engineering.Moreover,the main points of construction was discussed.The result shows that:The no-fines pervious concrete using aggregate of single grain grade exits the optimum quantity of cement and water-cement ratio;To aggregate of different grain grade,it is not exactly that the concrete of smaller size aggregate has higher strength when the quantity of cement is the same.The water permeability of no-fines pervious concrete has the better corresponding relations with its connect porosity ratio. |
