天津荣欢园地下车库超长超宽,采用补偿收缩混凝土结构自防水+聚合物水泥防水涂料双防水技术。HCSA膨胀剂优化设计混凝土配合比,混凝土限制膨胀率控制在0.015%~0.025%,膨胀加强带优化后浇带。外墙满涂Ⅱ型聚合物水泥防水涂料,厚度控制在0.4mm左右。除个别渗漏点外,整体防水效果较好。
Tianjin Rong Huan Park underground garage long extra wide, the use of compensated shrinkage of concrete structure of self-waterproof polymer waterproof polymer waterproof double waterproofing technology. HCSA expansion agent to optimize the design of concrete mix, concrete control the rate of expansion of 0.015% ~ 0.025%, expansion of the reinforced belt after pouring. Exterior wall covered with type Ⅱ polymer cement waterproof coating, thickness control in about 0.4mm. In addition to individual leakage point, the overall waterproof better.
