摘　　要：混凝土的保湿养护对干燥地区混凝土结构具有重要意义。透水模板(CPF)通过降低混凝土表层水灰比而提高混凝土耐久性,其中的保湿材料具有保持水分的作用。通过采用MOIST-200B型微波测湿仪检测混凝土贴衬与未贴衬的湿度状况,研究了保湿型非织造布模板衬对混凝土表层的养护作用。同时,采用空气渗透性试验与表层水吸附试验(ISAT)研究了透水衬里模板对混凝土的效果,试验表明透水衬里模板对高性能混凝土表层的空气渗透性与水吸附性的降低作用不明显。It is of great significance for concrete to be cured using controlled permeability formwork especially in dry area.Controlled permeability formwork（CPF ） could improve durability of concrete through decreasing the ratio of water and cement in concrete surface. CPF could also retain the water within it.The role of concrete curing using CPF or not was test.In addition, the permeability of concrete surface between the concrete which use CPF or not was analyzed through the air permeability test,the initial surface absorption of concrete test（ISAT ）.The testing results indicated that there was little effect on curing of concrete using controlled permeability formwork liner.
