Advantages of applying the mixture when guniting on vertical surfaces of building envelope

Abstract

Having studied the technological modes of applying the mixture by the guniting method on hard unyielding surfaces, we can conclude that the technology for applying building mixtures is formed depending on changes in a number of factors (including the strength characteristics and the rebound of the mixture from the vertical surface). Experimental study of the influence of the technological parameters of application on the efficiency of guniting with the classical method and application using a nozzle for vortex application allows us to visually detect the zones of rational application of this technology. Based on the experimental data, we carried out an analysis of the influence of the technological parameters of applying the mixture on the criterion indicators. For this, we investigated various methods [8, 9], processed the results and revealed dependencies, discovered unknown aspects of gunning with the use of a nozzle for vortex application of a construction mixture. The assessment showed a sufficient degree of coincidence of theoretical and experimental studies and the possibility of their practical application, on the basis of which we can conclude about the efficiency of the nozzle for the vortex application of the building mixture.
