Development of the optimal composition of gypsum self-leveling floors and comparative analysis with commercial mixtures

The article is devoted to the development of optimal composition of gypsum self-leveling floors by adding basalt fiber. Thestudyexaminestheeffect of there in forcing component on the main quality parameters including compressive strength, flexuralstrength, wear resistance and porosity. Laboratory tests were conducted for three experimental mixtures with different proportions of gypsum binder, water and basalt fiber. Scanning electron microscope microscopic analysis showed that the addition of basalt fiber increased the adhesion between fiber and gypsum, reduced porosity and improved mechanical properties. For comparison, the developed composition was analyzed along with three commercial mixtures presented on the Ukrainian market: “Budmeister D-319”, “Polymin TP-5” and “BaumitNivelloQuattro”. Commercial samples were evaluated for compressive and flexural strength, microstructural integrity and wear resistance. The study confirmed that the addition of basalt fiber to gypsum self-leveling floors significantly improves their mechanical performance, microstructural density and durability. Further studies are recommended to evaluate the long-term performance of the coatings, their thermal conductivity, cost effectiveness and environmental impact.
