Title of the articleOptimization of composition and investigation of the effect of complex hydrophobic-plasticizing additive on physico-technical properties, reinforced with Portland cement, clay soils
Abstract.Problem statement. Optimize the composition of the complex hydrophobic-plasticizing additive based on polycarboxylate and octyltriethoxysilane ether and investigate its effect on the physicotechnical properties of polymineral, kaolinite and montmorillonite clay reinforced with portland cement. Results. The main physico-technical properties of clay soils reinforced with Portland cement, modified with a complex hydrophobic-plasticizing additive, are studied. A graphical interpretation of the results of a mathematical model showing the effect of the components of a complex hydrophobic-plasticizing additive on a polymineral reinforced with portland cement (with a content of relic minerals greater than 85 %), kaolinic (with a kaolinite mineral content up to 95 %) and montmorillonite (with a montmorillonite mineral content up to 70 %) clay. Conclusions. The significance for the construction industry is that the introduction of a complex hydrophobic-plasticizing additive led to an increase in compressive strength of cement-reinforced polymineral clay by 102 %, kaolinite clay by 86 %, montmorillonite clay by 56 %, tensile strength at bending – by 89 %, 71 % and 28 %, frost-resistance – by 114 %, 50 % and 52 % respectively.
Keywords.ultimate compressive strength, ultimate tensile strength, freeze-thaw resistance, soil-cement, polymineral clay, kaolinic clay, montmorillonite clay.
