有机硅烷与透水衬里模板(CPF)都是通过降低混凝土表层渗透性而提高混凝土耐久性的技术,通过空气渗透性试验与表层水吸附试验(ISAT)分别研究了有机硅烷、透水衬里模板单独使用时,以及有机硅烷与透水衬里模板共同使用时对混凝土表面渗透性的影响,试验表明有机硅烷能有效降低普通混凝土表层水吸附作用但对空气渗透性没有明显影响,透水衬里模板对普通混凝土表层的空气渗透性与水吸附作用都有明显降低作用,有机硅烷和透水衬里模板同时使用能进一步提高混凝土表层上的抗渗透性。
Both organic silane and water-permeable lining templates (CPF) are techniques for improving the durability of concrete by reducing the permeability of the surface layer of the concrete. The organosilane and the water-permeable lining template were studied separately by the air permeability test and the surface water adsorption test (ISAT). , And the impact of organosilane and water-permeable lining template on the permeability of the concrete surface, the test shows that the organic silane can effectively reduce the ordinary concrete surface water adsorption but no significant effect on air permeability, permeable lining template on the surface of ordinary concrete air Permeation and water adsorption are significantly reduced. The use of organosilane and water-permeable lining templates at the same time can further increase the permeability of the concrete surface.
