在制造预制钢筋混凝土楼板时,利用一种新型临时性塑性填充料在固化的模板中形成工艺所需要的孔洞。可以提高预制钢筋混凝土楼板的质量。塑性填充料由珍珠岩、膨润土和防锈剂组成,它可以使预制钢筋混凝土楼板中的钢筋不受化学腐蚀的作用。塑性填充料具有但好的和易性,能够很方便地填塞到楼板的工艺孔洞中,并且,在混凝土楼板完全硬化后又很
In the manufacture of prefabricated reinforced concrete floors, a new type of temporary plastic filler is used to form the holes required for the process in the cured formwork. It can improve the quality of prefabricated reinforced concrete floors. The plastic filler is composed of perlite, bentonite and rust inhibitors, which can make the reinforcement in the prefabricated reinforced concrete floor free from chemical corrosion. The plastic filler has good workability, can be easily filled into the holes of the floor, and is very hard after the concrete floor is completely hardened.
