Original Abstract

Coating systems, not only in the building industry, have historically their irreplaceable role. Modern times, however, take on increasing responsibility for both the environment, the versatility of product use, and the reduction of production costs. The development of the new multifunctional geopolymer coating, therefore, clearly covers all of these global aspects. In this paper, the mechanical and rheological properties of various geopolymer pastes were investigated. The geopolymer mixtures were composed of metakaolin and various dosage of water glass solution with three different SiO2/Na2O ratios. The best mechanical properties were achieved for the mixture with content 90% of water glass and SiO2/Na2O ratio of 1.4. The rheological measurements showed high thixotropy of all mixtures and very low yield stress values.
