刚铺设的水泥砂浆地面的养护办法

水泥混凝土地坪摊铺完毕后,应及时进行养护。在养护初期,为了防止水泥混凝土被日晒雨淋,地坪养护宜采用喷洒养护剂或用塑料薄膜养护方式。也可采用覆盖能蓄水的旧麻袋、草袋等洒水养护方式。          

 After the paving of cement concrete floor, the maintenance should be timely. In the early stage of curing, in order to prevent the cement concrete from being exposed to the sun and rain, the maintenance of ground floor should be used to spray curing agent or plastic film curing. It can also be used to cover old sacks, straw bags, etc.

  喷洒了养护剂或做了抗滑构造的地坪必须有专人保护,严禁人、畜、车辆等破坏地坪。在达到设计强度的40%以后,撤除养护覆盖物后方可允许行人、车辆通行。     

  采用喷洒养护剂的养护方式,喷洒剂的喷洒厚度必须保证养护成膜。喷洒剂应满足保水率≧85%。保水率不合格或对水泥混凝提强度有影响的养护剂不得使用。

        The ground flat that sprayed curing agent or make anti-slip construction must have special person protect, forbid person, livestock, vehicle and so on destroy ground floor. After reaching 40% of the design intensity, the removal of the maintenance covering will allow pedestrians and vehicles to pass.

Using the curing method of spray curing agent, the spraying thickness of sprinkler shall ensure the curing of the film. Sprinkler should satisfy the water retention rate of 85%. The maintenance agents that are not qualified for the water retention or the strength of the cement mixing strength shall not be used.

 

   采用塑料薄膜养护时,其厚度要合适,在两块薄膜对接处,对接长度不得小于1米。塑料薄膜在野外地坪上必须盖严实,防止挂烂和被风吹破、掀起。

     When curing with plastic film, the thickness should be suitable, and the docking length should not be less than one meter in two thin film interconnections. The plastic film must be covered in the field to prevent the hanging and blowing.
