| Title of the article | Optimization of composition of soil-cement with complex additive based on organosilicon compounds |
| Abstract. | To enable the application of soil in road structures one of the most effective methods is the strengthening of its cement. Improving the quality of the material is an urgent problem that cannot be solved, in full, without modification of the chemical additive, affecting the structure and properties of soil-cement. Studies have shown that the solution of this problem is possible through the use of additives organosilicon compounds, allowing obtaining hydrophobic materials and electrolytes that give soil-cement high strength properties. Based on the analysis of scientific works to increase strength and frost resistance of building materials and conducted experiments obtained the complex, consisting of organosilicon octyltriethoxysilane and the electrolyte is sodium hydroxide. In the work the influence of the additive on the basis of octyltriethoxysilane and sodium hydroxide strength and frost resistance of soil-cement using mathematical modeling and the application of the method of experiment planning. The dependences of the influence of consumption of Portland cement, composition and dosages complex additives on the mechanical properties of the material. The composition of the modified soil-cement with regard to applications in the road pavement and the role of the components of comprehensive additives to increase the strength and hardiness optimized. |
