How to classify concrete hardness?
Before choosing the diamond tools, it is essential to know the hardness of concrete
The hardness of concrete is referenced by its compressive strength measured in Pounds per Square Inch (PSI). Cured concrete slabs vary widely in compressive strength; with moisture, temperature, design of mixture additives, cementitious materials and curing processes often determining their measured level of strength. The higher the compressive strength, the harder the material.
|Concrete Hardness||PSI||In Mpa||Typical Application|
|Very hard||8000 or more||60Mpa or More||Nuclear Plants|
|Soft||3000 or less||20Mpa or less||Sidewalks, Patios, Parking lots|
|Concrete Hardness||Mpa||Bond Types|
|Very hard||60Mpa or More||Very Soft|
|Soft||20Mpa or less||Hard|
