| Title of the article | Strength characteristics of soils stabilized with geopolymer binders for road construction |
| Abstract. | Problem statement. Modern standards place increased demands on the quality of the soils used in the foundation of the pavement, which stimulates the development and application of technologies for their reinforcement. However, currently, the use of man-made industrial waste in road construction is a particularly important problem. The development of technologies for soil stabilization and strengthening using steel production waste developed on the basis of alkaline modification as binders is relevant. The aim of this work is to conduct a comparative analysis of existing inorganic binders with the developed geopolymer binder for stabilizing the sub-grade of a highway. To achieve the goal, the following tasks were solved: study of the influence of Portland cement and unslaked ground lime on the strength characteristics of clay soil; study of the influence of steelmaking waste and geopolymer binder based on it on the strength characteristics of clay soil; determination of the effectiveness of the studied binders in stabilizing clay soils. Results. The strength characteristics of stabilized clay soil were obtained depending on various binders. It was found that the introduction of geopolymer binder in the amount of 2% and 4% into clay soil provides an increase in the adhesion area to 107.47 kPa and 134.13 kPa and a decrease in the angle of internal friction to 16.70 ° and 14.04 °, respectively. Conclusions. The conducted studies allowed to establish the nature of the influence of various binders on the strength characteristics of clay soil with a single-plane cut. It is shown that the geopolymer is not inferior in the obtained strength characteristics to clay soils stabilized by traditional binders. The obtained results are a prerequisite for further research of geopolymer binders in stabilizing and strengthening soils in road construction. |
