摘　　要：结合工程实际,运用空气渗透性、表面水吸附、回弹法等方法检验了混凝土的表面性能,对比评价了透水模板的使用效果,试验表明:使用透水模板的混凝土表层强度、抗空气、水吸附渗透能力均有改善,分析得出采用透水模板后混凝土表层变得更加密实,内部水化反应可以正常进行,从而提高了混凝土的耐久性。Combining with the performances in projects including air permeability,surface water absorption,and rebound method,the paper compares and evaluates the effect of the permeability effect,proves by the test that the concrete surface strength,anti-air,and water absorption permeability performance of the formwork,and analyzes the concrete surface after the permeability formwork are much tighter and the internal hy-dration reaction is normal,so it can improve the concrete durability.
