Abstract:

In the paper, it is proposed to use synthesized amorphous aluminosilicates as a modifying supplement in cement adhesive dry mixes. The results of the analysis of the chemical composition and microstructure of the developed supplement based on amorphous aluminosilicates used as a modifying supplement in the recipe of adhesive dry mixes are given. A method for evaluating the shear strength of a solution layer using the device GT 2.2.3 is proposed. The methods of testing and instrumentation for evaluating the bond strength of the solution layer are described. In the paper, the bond strength of the developed composition of tile adhesive based on cement with substrates made of gypsum, polystyrene foam (with reinforcing mesh) and foam concrete was evaluated. The results of the evaluation of the shear strength of a solution adhesive layer based on the developed recipe and the prototype relative to the substrate obtained using the developed method and the device GT 2.2.3 are presented. The obtained results were compared with the values of DIN EN 12004. It is established that the adhesive joint based on the developed recipe of the adhesive dry mix is resistant to peeling.
