    金刚砂耐磨环氧地坪施工在混凝土初凝前的原因

    熟悉金刚砂耐磨地坪施工工艺的朋友可能都知道,金刚砂耐磨地坪的最佳施工时间是在混凝土初凝前。对于经验丰富的金刚砂耐磨地坪施工师傅,会通过手指按压,混凝土的含水量和天气来判断。简单来说就是:当地面刚刚可以承受人的重量不下陷的时候,就是施工的时候。金刚砂耐磨环氧地坪在混凝土初凝之前进行施工,一方面可以起到压实地面的作用,另一方面也可以让金刚砂耐磨骨料在震动下渗透到下方。而且因为混凝土还具有可塑性,不会损害混凝土的结果。如果在初凝后施工,会对刚刚成型的混凝土结果造成一定损害。

    Friends familiar with the construction technology of diamond wear-resistant floor may know that the best construction time of diamond wear-resistant floor is before the initial setting of concrete。 For experienced builders of diamond sand wear-resistant floor, they will judge by finger pressing, concrete moisture content and weather。 Simply put: when the ground just can bear the weight of people does not sink, it is the time of construction。 The construction of diamond abrasion-resistant floor before the initial setting of concrete can not only play a compact role, but also let the diamond abrasion-resistant aggregate penetrate into the floor under vibration。 And because concrete also has plasticity, it will not damage the results of concrete。 If the concrete is constructed after initial setting, it will cause some damage to the results of the newly formed concrete。 金刚砂耐磨地坪施工的平整度主要靠水泥混凝土基层的平整度来控制,耐磨材料仅是表面很薄的一道致密层,所以控制混凝土初凝前表面的平整度是关键工序。建议严格控制水泥混凝土浇注时的平整度,可采用一前一后两次刮杠找平。另外,在两条混凝土相邻的施工缝处,由于靠近施工缝模板处,在耐磨地坪收光成型时抹光机不易打磨到,所以在施工缝处 容易引起高差。因此,在模板拆除后应进行施工缝清理工作。

    The construction smoothness of the diamond wear-resistant floor is mainly controlled by the smoothness of the cement concrete base. The wear-resistant material is only a thin dense layer on the surface, so the control of the smoothness of the surface before the initial setting of concrete is the key process. It is suggested that the smoothness of cement concrete should be strictly controlled, and one scraper and two scrapers should be used to leveling. In addition, in the two adjacent construction joints of concrete, because near the construction joints template, the polishing machine is not easy to polish when forming the wear-resistant floor, so it is easy to cause height difference at the construction joints. Therefore, the cleaning of construction joints should be carried out after the template is removed.
