长期以来,水磨石地面施工中的开磨时间,凭经验或试磨确定。由于无定量标准,故难以掌握。为了提高工效,加快施工速度,保证施工质量。我们做了水磨石的开磨强度试验,在唐山华新纺织厂35000平方米水磨石地面施工中,全部采用了软磨法,降低水磨石成本7％,取得了较好的效果。一、影响水磨石磨损速度的因素我们用磨损速度(即单位面积上,单位时间内磨去水磨石面层的厚度)来表示水磨石地面磨损难易的程度。影响水磨石磨损速度的因素较多,如地面本身的密实度,石子的强度及硬度,水泥在硬化
For a long time, the grinding time in terrazzo floor construction was determined by experience or test grinding. Because of the lack of quantitative standards, it is difficult to grasp. In order to improve work efficiency, speed up construction and ensure construction quality. We have done the terrazzo grinding strength test, in the 35,000 square meters terrazzo floor construction of Tangshan Huaxin Textile Factory, all adopted the soft grinding method to reduce the terrazzo cost 7%, and achieved good results. First, the impact of terrazzo wear rate of the factors We use the wear rate (that is, per unit area, unit time grinding terrazzo surface thickness) to represent the extent of terrazzo floor wear. There are many factors that affect the wear rate of terrazzo, such as the compactness of the ground itself, the strength and hardness of the stone, and the hardening of the cement.
