| Title of the article | Study of the influence of metallurgical waste on the physical and mechanical properties of soils |
| Abstract. | Problem statement. The road construction industry is in dire need of introducing cheaper and more efficient road construction materials that will improve the quality of road pavement, increase its service life, which in turn will reduce the cost of road maintenance. The use of manufacturing wastes for the production of road construction materials can help reduce the cost of road construction materials, simultaneously solving the problem of environmental pollution. The paper studies the effect of stabilizing additives on the physical and mechanical properties of loam. The objective of the work is to assess the effect of active mineral additives on the physical and mechanical properties of soil. To achieve this objective, the following tasks are solved: soil samples are selected and tested for compliance with regulatory requirements; the characteristics of "Minplast" mineral additive obtained on the basis of metallurgical waste and lime, which will be used as soil stabilizers, are determined; the physical and mechanical characteristics of the stabilized soil, as well as the bearing capacity index and the California bearing ratio, are assessed. Results. Modification of soil with a mineral additive increases its bearing capacity index by 1.5 times. The California bearing ratio increases by 20%. Introduction of "Minplast" mineral additive into the soil, in the amount of 2%, allows increasing the density and elastic modulus. In addition, a significant increase in the angle of internal friction is observed. Conclusions. The use of "Minplast" active mineral additive has significantly improved physical and mechanical characteristics of the soil. Low cost, compared to other mineral binders used as stabilizing additives, makes its use very promising. |
