Title of the articleThe study of the influence of organosilicon compounds on the performance of standard seals and physic-mechanical properties of soil-cement
Abstract.It is known that frost is one of the factors affecting the quality and durability of the materials. Theoretical studies have shown that the soil even with the strengthening of its Portland cement significantly loses its strength already at the first cycles of freezing and thawing. The most promising direction in solving this problem is the use of organ silicon compounds, which allows obtaining hydrophobic materials. The basis of the hydrophobization of soil-cement such additives is the phenomenon of chemical adsorption of mineral particles and formation on their surface monomolecular or polymolecular water repellent organosilicon polymer films. In this work the influence of the organosilicon compounds on the performance of standard seals and physico-mechanical properties of soil-cement. Mechanism of waterproofing soil chemical additives described. The effect of organosilicon compounds on the maximum density and optimum moisture content, tensile strength compressive and tensile bending and resistance soil-cement determined. Considered a number of organosilicon compounds that increase physical and mechanical properties of soil-cement that can be recommended for waterproofing and complex modifiers. The results obtained may be due to the manifestation and realization of the water-repellent effect of organosilicon compounds, which consists in the orientation of hydrophilic and hydrophobic chains in the material.
Keywords.soil-cement, organosilicon, optimum moisture content and maximum density, physical and mechanical properties.
