Soft Concrete Floor
Medium Hard Concrete Floor
Hard Concrete Floor
Diamond segments are manufactured using a combination of metal powders in specific proportions. They are then molded by cold pressing and fired by hot pressing. During the grinding process, the exposed diamonds effectively grind the concrete floor, while the fallen diamonds and metal powders wear and consume each other, exposing more diamonds to grind more floor. The hardness of the base material and the proportion of the diamond powder or segments affect the hardness of the resulting product. The consumption rate of diamond segments with various matrix hardnesses also varies.
The consumption ratio varies depending on the strength of the concrete being ground. It is therefore crucial to select the appropriate hard-bond diamond tool for grinding different hard-bond concrete.
1. During the grinding process, the diamond tool and the concrete floor do not undergo any consumption.
2. During the grinding process, the diamond tools are consumed at a rate that is not sufficient to achieve the desired results. In this case, it is necessary to use a greater number of diamond tools.
- Hard bond
- Medium hard bond
- Soft bond
The mineral content in concrete, water, and the way it is processed differs from country to country and region to region. This also affects the hardness of the concrete, which is why it is essential to test the strength of the floor before grinding the concrete floor using a Mohs hardness pen. Typically, a set of Mohs hardness pens contains four instruments that can assess the hardness of diverse mineral materials.
How to Use a Mohs Hardness Pen. Select the correct metal bond diamond tool for the job based on the scratches produced by the Mohs hardness pen on the ground against a mineral sample.
Soft concrete = hard bond diamond
Medium concrete = medium bond diamond
Hard concrete = soft bond diamond
Very hard concrete = super soft diamond
According to the actual situation of the concrete floor, Khonti Diamond Tools company can produce 8 x Soft or 6 x Hard metal bond diamond floor grinding discs.
Once we know the hardness of concrete, we can easily use this guideline to design the best formula for metal diamond tools to increase the life while also improving grinding sharpness. This will save more money and help produce the best results efficiently.
