摘要：以沙漠中风积砂为主要骨料，通过免烧结压制成型，研制了一种微孔生态透水材料预制件，并对其性能进行测试。结果表明：当孔隙率为15%左右，胶凝剂掺量为4.5%时，所制备透水材料的透水系数达2.3×10-2 cm/s，抗压强度为32.7 MPa；透水砖对城市路面径流污水中40～70 μm的悬浮物（SS）去除率达75%以上。与其它透水材料相比较，该透水产品透水时效长、吸声降噪性能强、铺装性价比高。

Abstract：Using desert aeolian sand as main aggregate and sintering-free compaction molding，a kind of preform product of microporous ecological pervious material was developed and its properties were studied. The results show that when the porosity is around 15% and the dosage of gelling agent is listed as 4.5%，the permeability coefficient is 2.3×10-2 cm/s，and the compressive strength can reach 32.7 MPa. The removal rate of 40～70 μm SS in urban pavement runoff sewage by permeable brick is more than 75%. Compared with other pervious materials，the pervious product has the advantages of long pervious time，strong sound absorption and noise reduction，and the highest cost-effective pavement.
