| Title of the article | Prospects for the use of fly ash in cement-based coatings of airfield sites |
| Abstract. | Problem statement. As part of the development of small aircraft in the Russian Federation, it is necessary to solve such a problem as the construction of airfield sites that ensure safe take-off and landing, while taking into account the all-season nature of their operation. This problem is especially acute in regions far from the central part of Russia. One of the relevant areas of solving this problem is the use of modification in airfield construction, when strengthening local soils. The purpose of the study is to determine the possibility of using ash and slag waste (fly ash) from thermal power plants of the Siberian Federal District in the construction of cement-based coatings of airfield sites. To achieve this the following tasks are solved: determining the effect of the quantitative and qualitative composition of cement-based mixtures with fly ash additives sealed with aqueous solutions of polyvinyl alcohol on strength and frost resistance; justification of the use of fly ash from thermal power plants in the Siberian Federal District as part of cement-based mixtures sealed with polyvinyl alcohol solutions of various concentrations during the construction of airfield site coverings. Results. The rationale for the use of fly ash from thermal power plants in the Siberian Federal District as part of cement-based mixtures sealed with solutions of polyvinyl alcohol of various concentrations is presented. The study found that the introduction of fly ash into the cement-based mixture provides an increase in strength while reducing the level of water absorption, uniform distribution of a film-forming solution of polyvinyl alcohol over the volume of the mixture, and also increases the density and frost resistance of cement-based soils. Strengthening of clay soils of cements modified with solutions of polyvinyl alcohol together with fly ash can be used in the construction of airfield sites. Conclusions. The significance of the results obtained for the construction of transport facilities lies in the fact that strengthening clay soils with cement and modifying them with solutions of polyvinyl alcohol together with fly ash from the Siberian Federal District can be used in the construction of airfield sites. The use of fly ash in the composition of cement-based mixtures provides the possibility of obtaining an economic effect, which consists in reducing the cost of building airfield sites compared with technology based on the use of stone materials. |
