Including 30% of representatives of the adhesives industry and flooring industry; 23% experts; 16% floor layers; 9% screed layers; 7% architects \/ site managers; 5% manufactures of measuring instruments and 10% others.<\/p>\n<p>Concerning the question \u201ehow to measure\u201c the attendees answered:<\/p>\n<p>Electrical moisture measurement (only): <strong>14%<\/strong><br \/>\nCM-method (only): <strong>21%<\/strong><br \/>\nElectrical moisture measurement and CM-method: <strong>65%<\/strong><br \/>\nDarr analysis: <strong>19%<\/strong><br \/>\nMicrowave analysis: <strong>2%<\/strong><\/p>\n<p>Note: Additionally to the electrical method and the CM-method namings of alternative methods (Darr analysis etc.) have been allowed. Especially experts measure moisture in building material on-site and in laboratories so that more than 100% of namings result.<\/p>\n<p>The survey pointed out clearly that \u00be of those polled using both  measure methods, the electrical moisture measurement and the CM-method (65% of the attendees), use the electrical moisture measurement as intermediate examination to determine a checkpoint for the Cm-method.<\/p>\n<p>About 2\/3 of those polled made good experiences with the CM-method, but about a half of them is satisfied with the electrical method.<\/p>\n<p>In fact the combination of both methods is best to define moisture in screeds. With the <a title=\"Material humidity measurements\" href=\"https:\/\/www.trotec24.com\/en-gb\/measuring-instruments\/humidity\/material-moisture\" target=\"_self\" class=\"broken_link\">electrical measuring instruments<\/a> you can control how screed desiccates und the user needn\u2019t conduct the complex CM-method at his visits at the construction sites. Finally if the metered values on the screen of the electronic moisture measuring instrument don\u2019t change he although has to conduct the <a title=\"CM-humidity measurement\" href=\"https:\/\/www.trotec24.com\/en-gb\/measuring-instruments\/humidity\/cm-measuring-instruments\" target=\"_self\" class=\"broken_link\">CM-method<\/a> \u2013 there\u2019s still no other way to handle it.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The topic humidity measuring in screeds remains an evergreen.
