Mineral alloy aggregate (corundum) ground hardener consists of a certain particle grade mineral alloy aggregate, special cement, other admixtures and admixtures. It is evenly spread on the concrete surface in the initial setting stage and processed by special means. This results in a high-performance wear-resistant floor that is integral with the concrete floor and has a high density and coloration.
The corundum floor is also a cement product. It is a product of high-grade cement mixed with different grades of quartz sand. It is of course characterized by cement products: the free Ca+ Mg+ ions are continuously precipitated from the pores to cause dust generation; The hydration cooperation is used in the loss of the last water, resulting in a lot of capillary pores, which in turn makes it not dense, so its strength and wear resistance are greatly reduced. Since the thickness of the corundum is generally 3 to 5 mm, it is very easy to fall off. If the time of cutting is not mastered. After the thickness of this layer is worn, the cement below starts to ash, so it is usually used after one year of use, even if it is waxed and maintained, it is inevitable to scratch and wear.
