混凝土 Moisture Testing

混凝土 Moisture Testing, continued

While concrete/water ratios make a difference in permeability, factors such as air humidity, 温度, 和 surface conditions also affect the rate at which moisture migrates through drying concrete.

Moisture meters are used to locate 和 measure moisture content in materials such as wood 和 concrete. 的y are often utilized by flooring installers 和 other testing applications to detect moisture up to 1” deep. It is very important to test concrete humidity as water continues to pass through even after it hardens. While concrete moisture doesn’t have a huge impact on outdoor applications, it is critical in indoor installations.

Problems arise from high levels of detected moisture. Trapped water can cause mold 和 mildew, bubbles in flooring, or even degradation of materials. No single test reveals everything about a concrete’s qualities. 的refore, multiple moisture tests are essential 和 should be utilized accordingly.

ASTM F2170标准 specify that in situ probes should be used to determine if a concrete slab is in good condition to be sealed or covered by a floor. This methodology of measurement provides accurate 和 reliable data for making installation decisions. Surface-based test methods are generally unreliable in evaluating moisture in a drying slab.

的 levels of moisture in a drying slab will be higher at the bottom but will disperse over time once the slab has been sealed. So, any testing method that does not take this into consideration 和 measure below the surface 和 into the slab will not provide accurate data as to what will occur after the flooring is installed.

Humboldt provides a variety of instruments utilizing different methodologies for concrete moisture testing.
