帕斯卡PSI-200是一种新型的水泥基渗透结晶型防水材料,可填充混凝土面板和趾板的表面及浅层裂缝,并在混凝土表面形成一道阻水隔层。同时由于其结晶体独有的渗透性,在与水分接触后将产生新的晶体(即二次结晶),进一步渗入混凝土内部,使混凝土结构的防水功能更持久,从而提高钢筋混凝土面板的抗渗性,最大限度地满足面板的耐久性及柔性要求。该施工方法简便,工期短。双河口大坝的混凝土面板和趾板使用帕斯卡PSI-200防水涂料进行防渗处理,取得了良好效果。
Pascal PSI-200 is a new cementitious capillary crystalline waterproofing material that fills the surface and shallow cracks in concrete and plinth panels and creates a water barrier on the concrete surface. At the same time, due to the unique permeability of its crystal body, new crystals (ie, secondary crystals) will be produced upon contact with moisture and will further penetrate into the interior of the concrete to prolong the waterproof function of the concrete structure and thereby improve the impermeability of the reinforced concrete panel , To maximize the durability and flexibility of the panel requirements. The construction method is simple, short construction period. Shuanghekou dam concrete slabs and plinths using Pascal PSI-200 waterproof coating for anti-seepage treatment, and achieved good results.
