Assessment of Adhesion of Geopolymer and Varnished Coatings by the Pull-Off Method

This paper presents the results of testing adhesion geopolymer coatings and varnishes with ceramic additives to concrete steel substrates. The measurement method used described in this article was pull-off method. test provides an easy way evaluate degree metal surfaces. device values for peel stress, which not only allows a quick determination coating substrate, but also makes it easier compare several each other. However, requires appropriate preparation, so attempt made determine its suitability layers. layer substrate are presented. As result study, higher strength found comparison applied on conventional concrete. Adhesion tests were conducted substrates both acrylic lacquer applied.
