| 摘 要： | 采用透水模板布浇筑大尺寸试验墩,从表面回弹、permit测试、吸水性、电通量等方面对比研究了透水模板布对混凝土力学性能及表层渗透性的影响。结果表明,采用透水模板布施工能使混凝土外观显著改善,表面力学性能大幅提高,同时混凝土表层渗透性大幅降低。透水模板布能有效提高混凝土表层性能,进而提高混凝土结构的耐久性。

| Abstract: | Controlled permeability formwork liner is used to pour large-scale test piers.The influence of controlled permeability formwork liner to the mechanical properties and surface permeability of concrete are studied by surface rebound,permit test,water absorption and electric flux.The results show that controlled permeability formwork liner can significantly improve the appearance of concrete and the surface mechanical properties,while the surface permeability of concrete decreased significantly.Controlled perm... |
