道路混凝土采用塑料薄膜养生,具有工艺先进、防水性强、施工文明等优点,是湿砂或水养生无可比拟的。混凝土用塑料薄膜养生,是在混凝土浇注成型后,其表面收浆不见浮水,用手指轻按不见指痕时,立即在混凝土表面喷(刷)一层塑料薄膜溶液,数分钟后形成一层塑料薄膜,将混凝土表面密封,使混凝土在养生过程中,依靠本身的水分进行水化作用,从而达到凝结硬化的目的。
The road concrete is made of plastic film and has the advantages of advanced technology, strong water resistance, construction civilization, etc. It is unmatched by wet sand or water health. The concrete plastic film is used to keep health. After the concrete is poured and molded, the surface of the concrete is not filled with floating water. When finger marks are pressed and no marks are seen, a layer of plastic film solution is sprayed (brushed) on the surface of the concrete, and a layer of plastic is formed after a few minutes. The film seals the surface of the concrete so that the concrete can be hydrated by its own moisture during the health process, thereby achieving the goal of setting and hardening.
