目前地下工程混凝土构筑物,在地下水位较高的情况下,竣工后,往往发现不同程度的局部渗水、漏水现象。为了解决这个问题,在所党支部的领导下,通过批林批孔运动,我们在学习兄弟单位经验的基础上,进行了一种防水涂料的试验研究,使混凝土的抗渗能力达到8公斤/厘米~2,不仅适应于混凝土潮湿表面,而且有一定耐酸、耐碱和抗老化的能力,同时还具有耐磨性能,在明开混凝土构筑物外涂时 At present, under the condition of high underground water level, the concrete structures of underground engineering often find partial seepage and water leakage after completion. In order to solve this problem, under the leadership of the party branch, through the pro-Lin bidding movement, we studied the experience of fraternal units, conducted a pilot study of waterproof coating, the impermeability of concrete reached 8 kg / Cm ~ 2, not only adapted to the wet surface of concrete, but also a certain acid, alkali and anti-aging ability, but also has wear resistance, open concrete structures in the open when
