It is generally accepted that the color and performance characteristics of liquid thermal insulation coatings are affected by the combined effect of various climatic factors such as solar radiation, temperature fluctuations, moisture, precipitation and others. This work presents the results of a scientific study of the full-scale exposure of coatings with regard to climatic ageing. Methods have been carried out, such as: spectrophotometry and direct scanning; determining adhesion, determining the adhesion strength of facing and protective coatings; and thermal conductivity and thermal resistance. As the results of the research work have shown, only in situ climatic tests, accompanied by the obligatory recording of the aggressive factors affecting the coating, make it possible to assess changes in the properties of epoxy coatings in full-scale conditions and, consequently, their climatic resistance by the methods of spectrophotometry and direct scanning. The ageing of polymer composites is known to be accompanied by a change not only in elasticity but also in color. Of the epoxy coatings tested, Etal-45M showed the greatest color variation during the in situ climate test. The most decorative resistant coatings are obtained using epoxy resin ED-20 + modified epoxy resin Etal-1440N.

“…These composites are “green” because of the incorporation waste admixtures and as a partial replacement for cement. Such admixtures mainly include fly ash, ground granulated blast furnace slag (GGBFS), and granite powder 3 – 5 . An additional reason for their use is the fact that these materials are waste from various industrial processes 6 .…”

In this study, a machine learning model for the precise manufacturing of green cementitious composites modified with granite powder sourced from quarry waste was designed. For this purpose, decision tree, random forest and AdaBoost ensemble models were used and compared. A database was created containing 216 sets of data based on an experimental study. The database consists of parameters such as the percentage of cement substituted with granite powder, time of testing and curing conditions. It was shown that this method for designing green cementitious composite mixes, in terms of predicting compressive strength using ensemble models and only three input parameters, can be more accurate and much more precise than the conventional approach. Moreover, to the best of the authors' knowledge, artificial intelligence has been one of the most effective and precise methods used in the design and manufacturing industry in recent decades. The simplicity of this method makes it more suitable for construction practice due to the ease of evaluating the input variables. As the push towards decreasing carbon emissions increases, a method for designing green cementitious composites without producing waste that is more precise than traditional tests performed in a laboratory is essential.

“…Waste rubber aggregates reduce the compressive and flexural strength of epoxy resin. 13 Waste glass powder 23 and recycling aggregate 24 improve the pull-off strength of the epoxy coating. It is shown in Hodna´et al 25 that waste glass powder used as a filler improves the hardness and tensile properties of the epoxy coating, while not deteriorating the pull-off strength and chemical resistance of the coating.…”

Epoxy coatings of floors are a very good solution for car repair workshops. Epoxy coatings provide the floor with resistance to oil, fuel, and grease staining. The floor surface is very easy to clean. To support sustainable development, a filler in the form of waste granite powder was added to the epoxy coating. In a car repair workshop, an epoxy coating of the floor was made according to the recipe previously developed in laboratory tests. The pull-off strength of the concrete substrate was tested before and after the mechanical treatment of concrete surface. The pull-off strength of the epoxy coating was also tested. The obtained results were compared with the laboratory results. It has been proved that the waste granite filler does not deteriorate the pull-off strength of the epoxy coating and thus its durability. The waste granite powder can be successfully applied as a filler in real epoxy coatings of floors.
