The astm standard calls for a specific process.

Acceptable moisture content percentage in concrete.

Clean out the holes using a wire brush and vacuum. A concrete moisture meter is a type of moisture meter used by installers of flooring to measure the moisture levels of concrete these meters have been used for decades to measure the moisture content in different materials and substances. Keep in mind that the relative humidity in the ground below the slab will be close to 100 regardless of the depth of the water table and that the humidity at the top of a concrete slab cannot. In other words at lower humidities concrete with a 5 5 moisture content is still very wet and approximately 25 litres per m3 more moisture has still to be dried out of it.

Concrete meters have evolved from the successful wood moisture meter as flooring contractors tried to use their wood meters to measure the moisture in concrete. Acceptable moisture levels in concrete according to astm standard when testing via astm f2170 the rh level of a concrete slab needs to be at or below 75 unless the flooring system manufacturer provides alternate guidelines. 26 build april may 2008 content of concrete is also lower at 3 9. Of concrete and another hole for each additional 1 000 sq.
