水泥地板的浇灌通常是用小型辗压机,把混凝土压实整平后,覆盖上苇席或草袋之类的东西,然后浇水保养,任其自然硬化。 瑞典求纳帕克公司的专家提供了一种新方法——真空浇灌法,可使制出的水泥地面质量提高很多。浇灌的前期操作,即压实、整平、覆盖苇席与一般作业并没有什么两样,但随后的新方法就不是浇水了,而是使用与苇席相联接的低真空泵,把混凝土中的多余水分抽 The concrete floor is usually watered by a small press machine. After the concrete is compacted and leveled, it is covered with a mat or a straw bag, then watered and maintained, allowing it to harden naturally. Sweden’s Nappa experts have provided a new method - vacuum irrigation, which can improve the quality of the cement floor. The initial operation of watering, ie, compaction, leveling, and covering the floor, is not the same as the normal operation. However, the subsequent new method is not watering. Instead, a low-vacuum pump connected to the mat is used to put the concrete in the concrete. Excess moisture extraction
