Choosing the appropriate bond for concrete grinding is essential to ensure efficiency, prolong tool lifespan, and achieve a high-quality finish. The bond affects how diamond segments perform on various surfaces, making it a key consideration for every project.

What Is Bond Hardness?

Bond hardness refers to how firmly the diamonds are held within the metal segment. A soft bond releases diamonds faster, which is ideal for hard concrete surfaces as it prevents glazing and ensures steady grinding performance. In contrast, a hard bond holds onto diamonds longer, making it suitable for softer concrete to prevent the tool from wearing down prematurely. The right balance ensures consistent performance and effective material removal.

Assessing Concrete Conditions

Before starting, contractors should evaluate the slab’s hardness using methods like the Mohs hardness test or scratch test. This ensures the selected bond suits the surface, avoiding unnecessary tool wear or inefficient grinding.

Additional elements such as coatings, moisture, and exposed aggregates can impact bond choice. Overlooking these factors may lead to uneven finishes or early tool damage, so thorough assessment is crucial.
