How To Select The Right Diamond Tools For A Concrete Grinder

When starting a diamond grinding project, this is the crucial decision to select the right diamond tools. You can also determine these by trial and error. With expertise, you may make an educated judgment on which disc will work best for any specific slab. Before going ahead, diamond tool manufacturers, there are a few simple statements:

  • Even using the best machine will not work well if you install the incorrect tooling.
  • There can be no such item as a faulty diamond disc. The disc must be right for that particular concrete.
  • Even on the same project, no two slabs are the same. On the same slab poured on the same day, a slab can differ from one section to the next.
  • There is no such thing as one diamond disc that fits all concrete floor types.
  • The ‘mpa’ of a slab may or may have nothing to do with how difficult it is to grind.
  • Premium discs will work well in a wider range of concrete hardness.

Considering the points, you must search for experienced diamond tool manufacturers for concrete grinders.

What Does Hard Concrete Means For Diamond Tool Manufacturers?

Many people get puzzled between hardness and strength when they are discussing hard concrete. You can measure strength in MPa and it is also a measure of compressive strength. Great compressive strength might indeed make things more difficult, but this isn’t always the case. This is because the aggregate and sand in high MPa and low MPa concrete are likely to be the same. The amount of cement and water used differs. This is also why 40 MPa concrete from the batching plant may not be 40 MPa when placed if the contractor adds water; it could be 15 MPa.

Note: 40MPa concrete cannot be poured because it is too stiff.

It is all about the type of dust produced during the grinding process when we talk about hardness. Hard concrete produces ultra-fine, talcum powder-like dust. This dust is extremely abrasive, and it does not sufficiently wear the diamond segment’s matrix. As a result, the diamond grit is exposed less and less, grinding finer, powdery dust; the segment stops grinding, and the segments may even grow hot and glaze over.

Therefore, excessively burnished slabs are difficult to grind quickly because the dust is too fine to be aggressive. As you grind a regular hardness slab, the top grinds fine, but when you get into aggregate, the dust formed by the aggregate may be too fine to wear the matrix sufficiently, causing it to grind slowly. The dust from the aggregate could be abrasive and grind too well, opening up the diamond segment too much and causing rapid wear.

In addition, the abrasiveness and aggregate will differ depending on the type of sand used. It all comes down to practice and examining your diamond tooling regularly.

Soft or water-damaged concrete generates very soft, gritty, sandy dust, which is too aggressive for most discs and causes them to wear out quickly. This is not the disc’s fault. It is simply a matter of utilizing the incorrect tooling and/or failing to inspect regularly.
