MPA For Concrete Grinding

So What Does MPA For Concrete Grinding Mean?

What concrete hardness means for the concrete grinding industry is that the surface you are grinding will be either soft or hard. A 25 MPA concrete is very soft generally rain damaged and powdery and something that says 50 MPA which is very hard, generally curing compound applied or densified.

It’s really hard to tell until you start grinding the concrete.

– We recommend starting with a hard bond diamond and see if the grinding is quick enough.

– If too slow or not cutting at all, change to a soft bond but check the wear on the diamond after 10 mins or to make sure it’s not wearing too quickly.

A “Mohs Hardness Test Kit” can be used to also test the MPA of the concrete slab

The Mohs Hardness Test Kit is the perfect hardness tester for floors – to help choose the right diamond grinding tool for your job.

Mohs’ hardness is a measure of the relative hardness and resistance to scratching between minerals. Using the Mohs Hardness Tester Kit to determine the hardness or the scratchability of your concrete is useful for identifying the best diamonds to use on the job.

Once you have determined the hardness of the concrete you can make informed decisions about which diamonds to use without taking the risk they will wear out too fast or glaze over.

Taking the time to test your slab before grinding will allow you to get a longer grinding life out of your diamonds, saving you thousands of dollars in lost diamonds or unproductive work.
