Concrete Floor Hardness

The rebound hammer method also commonly referred to the schmidt hammer is a test to check the impact strength of a concrete substrate.

Concrete floor hardness.

The map below gives us a rough idea of what concrete hardness looks like. It is called the mohs scale of mineral hardness. The scale on the hammer then produces a reading in psi. It is a scale of 1 10 in which 10 is the hardest and represents the hardness of a diamond.

Everdure caltite system or 3cc system or aquapel superplastet. Abrasion resistance increased 400 600. Concrete is the only material that beats it but it needs to be properly sealed and maintained. What is grade of concrete.

Mohs measure of hardness scale scratch test. Use a long level and tape measure to check that the floor is level. Ground damp general floors. Check your wood flooring manufacturer s recommendations and sand any high spots with a concrete grinder.

40 increased hardness low dust 20 30 less shrinkage. Typically the floor must be level and uniform within 3 16 inch every 10 feet. Friedrich mohs was a german geologist. Superplastet recommended to enhance all concrete floors.

Determine the overall hardness or softness of your concrete or stone surface. Epoxy floor coating makes renders concrete exceptionally durable. General traffic and wear. Concrete is made up of various elements of different hardness and densities that vary from region to region.

This hammer has a piston that is engaged easily by the user then when pushed on to the concrete fires. Grade of concrete is denoted by prefixing m to the desired strength in mpa. Improve hardness on concrete floors in areas of industrial activity it is essential that the concrete floor is maintained in good condition despite the traffic of heavy machinery. In 1812 he invented a test to tell the hardness of minerals.
