For contractors, the right kind of tool is essential to any project. It is especially the case if you work with concrete. As the most common building material, concrete needs a lot of work to bring out its aesthetic value. For a construction worker, this starts with choosing the right grinding blade for the job. Your choice will, however, be dictated upon by the compressive strength of the concrete. Get this part wrong, and you will be setting your tools up for damage. This article guides on choosing the concrete grinding blade bond type. Read on. 

Hard Concrete -- When preparing to grind a hard concrete, it is essential that your tool be able to handle the high compressive strength. It means that the diamonds should be released by the bond as soon as the surface diamonds wear off. It is for this reason that a grinding blade with a soft bond is the best for grinding hard concrete. The soft bond will ensure that it releases surface diamonds at the point of maximum utilisation. If you choose a hard bond, then it will hold the diamond grit for too long and consequently cause the tool to overheat and cause a potential fire. Ultimately, choose soft bond for every project that involves hard or hardened concrete.

Medium-hard Concrete -- Unlike hard concrete, medium-hard concrete does not have high compressive strength. Concrete curbs and slabs are great examples of medium-hard concrete products. For such a material, a medium-hard bond is needed to ensure a balance between keeping the blade exposed during grinding and wearing it off at the right rate. A medium-hard bond, therefore, gives the grinding blade the important productive life without the contractor having to spend money on a blade with a more robust bond. Most universal grinder blades are made of a medium-hard bond.

Soft and Abrasive -- Concrete tiles are an excellent example of soft concrete. When used on roofs for aesthetic purposes, they must be ground and given a smooth surface. Since it is easy to work on soft concrete, it is essential that the bond holds the diamond grit long enough to get the most out of the tool. If a soft bond is used, then the diamonds will be released even before they entirely wear off thus lowering the productivity of the diamond blade. A solid bond, however, ensures the bond holds the diamonds until they wear off, thereby enhancing maximum utilisation. If used correctly, such a blade can last long thus saving the business money that is used in replacing prematurely lost diamond grit.
